fractures and gas emissions are closely related to the geology of coal measure rocks and their distances from mining activity. In addition to the overall reservoir and strength properties, the types and thicknesses of coal measure rocks at the roof of a mined coal seam cause borehole stability problems during et al. (2007)
Most of the mines were simple bell pits, in which a central shaft was dug down to the coal measures, and widened at the bottom as coal was removed. As much coal as possible was removed until the roof showed signs of collapse, at which time the pit would be abandoned, and a new replacement dug nearby.
