Global methane emissions from coal mining, 2010 to 2100, bcm. This study estimates how much the increasing depth contributes to an increase in methane emissions from underground mines. To isolate the effect of increasing mining depth on methane emissions, the authors also calculated CMM and AMM emissions using a constant CMM gas content of 13.2
Coal is mined by two methods surface or 39opencast39 mining or underground or 39deep39 mining. The choice of mining method largely depends on the geology of the coal deposit.
A detailed mine design was created for four pits, R02N, R02S, R01N and R01S. These designs were completed to a short term planning level of detail which incorporated ramps to the coal floor for ten progressive strips. A total of seven coal seams of varying seam and interburden thickness were created in Excel dipping NorthEast between 6 to 8.
