The night is waning into dawn, and the air is thick with smoke and desperate moves. The mine mill is still churning off in the distance. The odds are against you – what to do?

Mining Subsidence and Loss of Water to Mines

The old adage “a picture is worth a thousand words” comes to mind when you look at the above photos. I was talking to a colleague about his trip to Timmins, Ontario for an Undergraduate Geological Engineering field trip to visit the old gold and base metal mines. I too had to share a few [...]
Design A Mine Waste Facility: Guidance From Wisconsin
Posted in acid mine drainage, environmental, Law (Mining), mining, Tailings, Underground, Waste Rock, tagged law, Reclamation, Tailings, Waste Rock, Wisconsin on February 14, 2012 | Leave a Comment »
The Wisconsin legislature has just posted a proposed new law on mining in the state. The full document is available at this link. At 191 pages it is not a short read; but it is a must-read. And it is a fascinating read. It is serious and sometimes frivolous. Consider these sections that caught my eye on [...]
The Dark Side of Mining: Pasta Carbonera
Posted in Mining history, Underground, tagged Iowa, laborer, mine, pasta on October 19, 2011 | 7 Comments »
In a now-demolished farm house in Iowa I taught the older grandsons to make pasta carbonera. It is easy: while pasta (any type) boils in hot water, in a pan fry bacon and onion; throw the boiled pasta into the pan; break in a few eggs; mix the whole until the eggs are cooked; eat [...]
Massey Energy denies report of responsibility for Upper Big Branch mine deaths
Posted in About the news, Coal, safety, Underground, tagged big branch mine, Coal, death, massey energy, politicians on May 20, 2011 | Leave a Comment »
This report should be mandatory reading for all in the mining industry. If you are a Democrat you will believe it, and believe something should be done—particularly a change in the law and more enforcement of lax and dishonest mine operators. If you are a Republican, you will ignore it, attack it, and say [...]
Acid Mine Drainage threatens Kwa Thema, South Africa. Is this really worse than Global Warming?
Posted in acid mine drainage, Africa, environmental, Global Warming, Gold, Reclamation, Tailings, Underground, Uranium, tagged AMD, East Geduld, Kwa thema, pollution, slimes dam, Tailings, Witwatersrand on April 28, 2011 | 1 Comment »
Growing up on the East Geduld Mine, a gold mine at the far east end of the South African Witwatersrand, we often went to play around the slimes dams and the pools of orange, green, and blue waters that dotted the landscape. Our parent forbade us to go there, for there were stories [...]

Mine-Mill Integration Jobs

The big idea is that you put your mill deep underground. Less noise, less dust, no surface run-off to manage. You send only the concentrate or refined product to the surface, thereby saving on haulage costs. Maybe you can use the waste rock to backfill the stopes. I am not sure what you would do [...]
Gold Mining: Das Rheingold and the Price of Gold
Posted in Gold, opera, Underground, tagged das rheingold, fricka, gold price, loge, MET, mining, opera, Palin, wagner, wotan on October 11, 2010 | 1 Comment »
The price of gold rises daily. Some news feeds have degenerated into infinite streams of platitudes about why the price of gold will climb every higher. Or burst as the next bubble to be charged to the taxpayer. Seems to me that while a few may benefit from the infinite rise in the price of [...]
2010 Mining Salaries from E&MJ
Posted in Jobs and Salaries, Open Pit, Underground, tagged E&MJ, journal, salaries on September 11, 2010 | Leave a Comment »
Engineering and Mining Journal (E&MJ) is published by Mining-Media. It arrives by no action on my part on my desk. There it joins the pile of magazines on mining that fall like leaves in autumn. Being a magazine junkie, I flip through them all. I avoid the articles on new trucks–those articles are surely planted [...]
