The Hazards of 19th Century Coal Mining eHISTORY

There were two big engineering problems in mining coal underground: A system to drain water from the mine. A system to ventilate the mine and to provide fresh air to the miners. A special problem in coal mines was the methane (a gas) that sometimes accompanied coal, and which could--and too often did--catch fire and explode. Andrew Roy was one ... Learn More

Opportunities and Challenges in Deep Mining A Brief

Aug 01, 2017 (3) With the rapid development of modern technologies, many critical problems restricting the progress of deep mining will be conquered, either independently or by the combination of intelligent mining, enhanced continuous mining for metal mines, and fluidized mining of deep coal resources, all of which represent the dominant approaches to deep ...

The Coal Mining Industry Is Collapsing and Communities

Nov 23, 2020 The collapse of the coal mining industry has already begun and has only accelerated during the coal-friendly Trump administration. Although the industry weathered a string of major bankruptcies from 2015 to 2018 without seeing a significant increase in mine abandonments, those bankruptcies merely set the stage for the current crisis.

Environmental Issues With Mining Mining Environmental

Small and large mining operations across the globe, both surface mining and underground mining, have contributed heavily to environmental issues. What Is Mining. Mining refers to the extraction of metals and minerals from the Earth. The most common types of mining include: coal mining, gold mining, uranium mining, and silver mining. Learn More

Coal and the environment U.S. Energy Information

Dec 01, 2020 Surface mines (sometimes called strip mines) were the source of about 62% of the coal mined in the United States in 2019. These mining operations remove the soil and rock above coal deposits, or seams. The largest surface mines in the United States are in Wyoming's Powder River Basin, where coal deposits are close to the surface and are up to ... Learn More

DNR Reclamation Abandoned Mine Problems

Acid mine drainage is the most severe and well-recognized environmental problem related to coal mining and can impact surface waters, including lakes, ponds, creeks, and even entire watersheds. AMD is water typically with a pH less than 4 that drains from mine workings and from mine spoils, and coal refuse (called acid rock drainage). Learn More

Assessing Emissions from Active and Abandoned Coal Mines

Coal mine and abandoned mine methane resource assessments and overcoming these difficulties require knowledge of geology, panel layout, production wells, ventilation fans, and availability of different data types and data sources.
