Coal mechanics
WebCoal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. … WebFeb 21, 2024 · Coal pores and fractures vary in geometric structure, size distribution, and compressibility in different directions, referred to as the anisotropy of coal pores and fractures (APF). For high-dip coal seams, this anisotropy impacts coal reservoirs more severely owing to stress variations.
