摘要
应用UDEC2D计算程序,模拟了某矿水平与倾斜联合布置的折线型综采面,揭示了综放开采过程中的采场覆岩与顶煤的运移规律及相应的应力场、破坏场的变化特征,并采用FLAC3D对沿折线型综采面布置的支架的受力及其运移特征进行了分析,研究结果对现场工程实践有一定的指导意义。
The rules of coal and rock movement,the characteristics of deformation and failure of coal,and the major principal stress in the process of top-coal caving in steep thick seam are analyzed by using UDEC2D.The characteristics of stress and movement of support structure at top-coal caving face are investigated by using FLAC3D.The simulation results agree with the field conditions.
