Mostly working in with the engineers to get blast designs marked up for drilling or lasers put in to guide development headings. Laser scanning stopes would be another big part, whenever they are empty or cave in we need to calculate volumes and see how much the ore is diluted.

Managing survey control would be another big one, extending it along new areas and doing checks. In technical services the ratio is probably 1 in 5 and I would say it's less for operators. Maybe 1 in 15, they have had a big hiring round and took on all female operators trying to diversify the group.

Nothing underground as such, a few large seismic events nearby had me running. Some really big ones lift 70 tonne loaders off the ground. At my old workplace a contractor died in a rockfall incident, and even though I didn't know him it really hit home how quickly things can change. I came close to a few rockfalls in open pit, had a spotter with me to scream if there was something coming down.

Since that incident they stopped doing that, looking back that was by far the most dangerous job I've had. So technically you live under the rock and still have better internet technology than most of Australia. Thanks to MTM that we have! Or you would still prefer doing what you doing to earn a bit more? So it breaks up the day and I get access to heaps of expensive surveying gear that I wouldn't otherwise get exposed to such as drones, scanners, radar etc. I can't see myself here forever, a lot of mine surveyors are quite young and the physical side of it would be catch up with you as you get older.

My girlfriend is a professional as well, so the time away from home is hard as she is usually working when i get back home during the week. A nice six figure job in the city and going home every night is where I dream to be in less than 6 years time.

We drove through there 3 years ago, and whilst Strahan is amazing, it was depressing how delapidated and 'cold' Queenstown was. There are a few nearby you have Mt Lyell in Queenstown which still has huge reserves but in care and maintenance at the current time due to company issues in India. Henty, Rosebery and avebery are active and fairly large operations.

And you have a few small privately run mineral mines hidden away in Dundas and surrounding areas. Most satisfying part would be how much impact I can have on the wider operation. I'm only 25 and I never thought I would have that much significant input into problem solving a job or people coming to me for advice about things. But considering I'm one of the only people on my shift in this role and that I've proved myself in the time that I've been working has been great.

Most people look down on younger people as too ambitious or stubborn in a lot of ways, but it's great that I get the support structure here. I heard few years back few mine workers posted a video dancing in the mine…they were sacked for flouting safety rules. Is that really that big an issue. There are lots of legal issues which go with this.

Even not following the correct pathway ie. More like a repetition thing so people know that they shouldn't flout them. Of course, if they do then they have to face the consequences. Yeah that video was at Henty, most got let go for that.

Mobile phones underground are a big no no if you get caught you will be under a pretty heavy investigation, if not let go. Some sites are far more serious than others, if you work for bhp or rio something as simple as not parking properly underground or stepping up onto a stockpile will have you dismissed. It's a very serious industry when it comes to saftey and most sites have a zero tolerance policy for cutting corners.

Hey everyone, I have been working in mining for the past 4 years, 2 years spent as a vac student during uni and the other 2 in a full time surveying role. Any questions on the industry or my role feel free to ask! Introduce Yourself. Was your vac role in surveying as well or were you being cycled through other engineering roles? Who is responsible for injuries at work? Do they cover or did you sign your life away? Is it same temp in winter?

Wonder if it can be used for heating normal houses. Thank you. What's a typical day in your role? What are the ratio of females to male employees? Has there been any accidents that affected you physically or mentally? Glad I can make an interesting thread! I am asking to see if I should leave my office job and work at mines instead :D.

Question, is this mine by any chance near Strahan?

Every few years we get a contracting mob to come in and do some check surveys, we have one coming soon since we have to join up two distant areas.

Not usually on the main declines due to holding up traffic, during mine maintenance shuts we go down and do check surveys. Minimum station resection with good residuals to traverse forward. What size drives do you have? MS60 is a awesome bit of gear. Are you using Surpac? Yeah it gets pretty miserable, not helped by the fact Tassie has the highest thermal gradient in Aus. Mostly 5. It is a good bit of kit, infinity has a lot left to be desired though.

Surpac for now, we are transitioning to Deswik very soon. Around wet bulb. For reference we aren't allowed to work in areas above 34 wet bulb. They give us electrolytes to help manage the fluid loss but you can't stay in headings that hot and do physical work for very long.

Cools down a little bit, if trucks and stuff and working nearby it gets steamy very quickly. They have geothermal heating in a few industrial buildings in Hobart. Very very expensive to set up. DiscoJango: The ventilation runs on a circuit, you have surface intake and exhaust fans which assist the natural convection flow along.

Vent doors in various parts separate return airways from fresh ones, you are only allowed in these return airways with gas monitors. The fresh air circuits go down the main declines, any drives off this circuit have huge electric fans to force air through the levels where it's needed.

You don't usually work in close proximity to the machinery, if you do it just gets too hot. The fumes aren't too bad, can sting your eyes a bit but I leave a few minutes for the air to clear before going in. They have fume exclusion zones when we fire development headings or large production stopes, the fumes from a firing will knock you out so no risks are taken there. Barefoot Miner: How physically fit do you need to be to become a miner? And it is common to see miners with an ethnic background?

Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet. Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal. As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine.

In a hexadecimal system, each digit has 16 possibilities. But our numeric system only offers 10 ways of representing numbers zero through nine. That's why you have to stick letters in, specifically letters a, b, c, d, e, and f. If you are mining bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash.

Remember that ELI5 analogy, where I wrote the number 19 on a piece of paper and put it in a sealed envelope? In bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash.

A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about. In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on earth would you want to do that?

The screenshot below, taken from the site Blockchain. You are looking at a summary of everything that happened when block was mined. The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by Antpool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below.

As you see here, their contribution to the Bitcoin community is that they confirmed transactions for this block. If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with zeros—at least eight zeros and up to 63 zeros. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol.

No target can be greater than this number:. Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. You'd have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined bitcoin. Mining pools are comparable to those Powerball clubs whose members buy lottery tickets en masse and agree to share any winnings.

A disproportionately large number of blocks are mined by pools rather than by individual miners. In other words, it's literally just a numbers game. You cannot guess the pattern or make a prediction based on previous target hashes. Not great odds if you're working on your own, even with a tremendously powerful mining rig.

Not only do miners have to factor in the costs associated with expensive equipment necessary to stand a chance of solving a hash problem. They must also consider the significant amount of electrical power mining rigs utilize in generating vast quantities of nonces in search of the solution. All told, bitcoin mining is largely unprofitable for most individual miners as of this writing.

Source: Cryptocompare. Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion of the total mining power on the network. Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own.

For instance, a mining card that one could purchase for a couple of thousand dollars would represent less than 0. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse. The miner may never recoup their investment. The answer to this problem is mining pools. By working together in a pool and sharing the payouts among all participants, miners can get a steady flow of bitcoin starting the day they activate their miner.

As mentioned above, the easiest way to acquire bitcoin is to simply buy it on one of the many exchanges. Alternately, you can always leverage the "pickaxe strategy. Or, to put it in modern terms, invest in the companies that manufacture those pickaxes. In a cryptocurrency context, the pickaxe equivalent would be a company that manufactures equipment used for Bitcoin mining.

The legality of Bitcoin mining depends entirely on your geographic location. The concept of Bitcoin can threaten the dominance of fiat currencies and government control over the financial markets. For this reason, Bitcoin is completely illegal in certain places. Bitcoin ownership and mining are legal in more countries than not. The risks of mining are that of financial risk and a regulatory one.

As mentioned, Bitcoin mining, and mining in general, is a financial risk. One could go through all the effort of purchasing hundreds or thousands of dollars worth of mining equipment only to have no return on their investment. That said, this risk can be mitigated by joining mining pools. If you are considering mining and live in an area that it is prohibited you should reconsider.

It may also be a good idea to research your countries regulation and overall sentiment towards cryptocurrency before investing in mining equipment. Your Money. Personal Finance. Your Practice.

Is Bitcoin Mining Legal? Risks of Mining. Key Takeaways By mining, you can earn cryptocurrency without having to put down money for it. Bitcoin miners receive Bitcoin as a reward for completing "blocks" of verified transactions which are added to the blockchain. Mining rewards are paid to the miner who discovers a solution to a complex hashing puzzle first, and the probability that a participant will be the one to discover the solution is related to the portion of the total mining power on the network.

Article Sources. Investopedia requires writers to use primary sources to support their work. These include white papers, government data, original reporting, and interviews with industry experts. We also reference original research from other reputable publishers where appropriate. Unfortunately most older machines are now no longer profitable even in China.

The Bitmain S9 has been operational since and interestingly enough they are still being used in Venezuela and Iran where electricity is so cheap that it outweighs the risk of confiscation. There may, eventually, be more reputable sources of sub 2 cents electricity as the access to solar and wind improves in North America. For the individual miner, the only hope of competing with operations that have access to such cheap electricity is to send your machines to those farms themselves.

Not many farms offer this as a service though. These days, every miner needs to mine through a mining pool. Whether you are mining with one machine, or several thousand, the network of Bitcoin mining machines is so large that your chances of regularly finding a block and therefore earning the block reward and transaction fees is very low.

With one block per 10 mins they may have to wait 16 years to mine that one block. The oldest two pools are Slush Pool and F2Pool. Here comes the science part…. Pool fees are normally 2. Choosing the right mining pool is very important, as you will receive your mined bitcoin sent from the pool payouts every day.

An often overlooked facet of mining profitability is the fees one pays to sell the Bitcoin one mines. If you are a small time miner, you may have to sell your coins on a retail exchange like kraken or Binance. Sometimes your fees are low but sometimes your fees are high - it really just depends on the fee structure of the exchange and the state of the orderbook at the moment. However, if you are a professional miner like F2 or Bitmain, you likely have really advantageous deals with OTC desks to sell your coins at little to no fees - depending on the state of the market.

Some miners are even paid above spot price for their coins. If you think you have what it takes be mine profitably, we suggest you make sure first by using our mining profitability calculator. Bitcoin farms that operate at scale use these advantages to maximize their returns. As the difficulty of mining bitcoin increases, and the price lags behind, it is becoming harder and harder for small miners to make a profit.

It all comes down to scale and access to cheaper prices. When people enter the space, without prior relationships, they struggle to compete with established mining operations. Bitcoin mining is starting to resemble similar industries as more money flows in and people start to suit up. With increased leverage, margins are lower across the whole sector.

Soon, large scale miners will be able to hedge their operations with financial tooling to lock in profits, whilst bringing in USD denominated investments like loans or for equity. As mining becomes more professional , it will make things even harder for DIY miners. If you have put in the effort to learn about mining, and you have found a location with low cost electricity for your machines, then you still need to consider where to store the bitcoin that you mine.

It is possible to mine direct from the pool to an exchange , but we recommend you keep your bitcoin in a wallet where you have access to the private keys. No, and in the case of Bitcoin, it almost never was. There was a time where one could profitably mine Bitcoin with GPUs, but again…today, you really must have an ASIC and a deal witha power company to make any money mining Bitcoin in The average home miner is unlikely to recoup the cost of mining hardware and electricity.

Profiting on your own is highly unlikely. The situation may improve in the future once ASIC mining hardware innovation reaches the point of diminishing returns. That, coupled with cheap, hopefully sustainable power solutions that retail customers can access in some shape or form, may once again make Bitcoin mining profitable to small individual miners around the world.

If small miners can re-enter the network it greatly increases decentralization and supports the original intentions of Satoshi Nakamoto even further.
