ABSTRACT The pH of coal-mine drainage in Pennsylvania has a bimodal frequency distribution, with modes at pH 2.5 to 4 (acidic) and pH 6 to 7 (near neutral). Although iron-disulfide and calcareous minerals comprise only a few percent, or less, of the coal-bearing rock, these minerals are highly reactive and are mainly responsible for the . ...

COAL MINING AND THE RESOURCE CURSE IN THE EASTERN UNITED STATES ... ABSTRACT.

Abstract. As a major greenhouse gas, methane, which is directly vented from the coal‐mine to the atmosphere, has not yet drawn sufficient attention. To address this problem, we report a methane nano‐trap that features oppositely adjacent open metal sites and dense alkyl groups in a metal–organic framework (MOF).

Abstract. Coal mining is one of the core industries that contribute to the economic development of a country but deteriorate theenvironment. Being the primary source of energy coal has becomeessential to meet the energy demand of a country.

Abstract "Coal mine methane (CMM) and abandoned mine methane (AMM), are by-products of underground coal mining. The quantity and the emission rate of CMM and AMM may vary depending on the type of mine, gas content of the mined coal seam, and gas sourced from strata and coal beds in overlying and underlying formations affected by mining. ...

The history of coal mining goes back thousands of years. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity. Coal mining continues as an important economic activity today.
