In a particularly spectacular case in the German Saar region (another historical coal-mining area), a suspected mine collapse in 2008 created an earthquake measuring 4.0 on the Richter magnitude scale, causing some damage to houses. Previously, smaller earthquakes had become increasingly common and coal mining was temporarily suspended in the area.
In a 2004 effort to foster positive public opinion of coal, many large coal mining companies, electric utilities, and railroads in the U.S. launched a high-profile marketing campaign to convince the American public that coal-fired power can be environmentally sustainable, despite the fact that coal is the largest contributor of CO 2 emissions ...

Machinery trying to mine the coal may not be able to reach the displaced seam, if the displacement is too large. Coal mines use a combination of boreholes and high-resolution seismic reflection data to identify the larger faults and avoid the most faulted areas at the mine planning stage. [1]
This disease is common in coal workers due to the inhalation of coal and silica dust in mining sites. Appalachia emerges as the hotspot of this disease, even in lower-class neighborhoods. Minimal screening of the disease has been registered even after passing the Coal Mine Health and Safety Act as early as 1969.

In 1810, 176,000 short tons of bituminous coal, and 2,000 tons of anthracite coal, were mined in the United States. American coal mining grew rapidly in the early 1820s, doubling or tripling every decade. Anthracite mining overtook bituminous coal mining in the 1840s; from 1843 through 1868, more anthracite was mined than bituminous coal.
