摘要
为合理并充分利用化石能源,使经济效益最大化,提高煤炭回采率尤为重要。文章以岩石力学及岩石破坏准则为依据,运用BAQUS有限元模拟软件,对彬长矿区水帘洞煤矿三采区4煤上行开采方法的可行性进行研究,为彬长矿区同地质条件矿井的遗留煤层开采提供了理论依据。
In order to make full use of fossil fuels,maximize economic benefits,it is particularly important to improve coal recovery rate. Based on the theory of rock mechanics and rock failure criterion,the feasibility of the ascending mining method for 4#coal seam in third panel of Shuiliandong Coal Mine in Binchang mining area was studied by using BAQUS finite element simulation software,which can provide theoretical basis for mining the remained coal seams with similar geological conditions in Binchang mining area.
