Effects of Different Factors on the Mining of Extra-Thick Coal Seam
Based on the mining case of Dafosi Coal Mine in Shaanxi Province, which is a typical coal mine with extra-thick coal seam, the effects of mining width, buried depth and rock grade on the ground surface deformation and sur-rounding rock stress have been studied by numerical experiments. It is found that both of the ground surface settlement (SS) and Horizontal Displacement (HD) increased with the increase of the mining width, the weaken of the rock grade and the decrease of the buried depth.
