浅埋工作面矿山压力显现规律模拟研究

NUMERICAL SIMULATION ON MOVEMENT RULE OF SHALLOW COAL SEAM

摘要: 本文利用SFPA^2D岩石破断过程分析系统软件,对神府东胜矿区活鸡兔煤矿浅埋煤层首产工作面上覆岩层在采动后的活动规律进行了动态仿真模拟,并根据模拟结果,分析了随着工作面采动和推进,上覆岩层的破断过程、特征与来压特点。

Abstract: In this paper,the SFPA^2D(Stratum Failure Process Analysis) software is used to simulate the movement rule of overlying strata when the shallow coal seam was extracted in the Huojitu Mine of Shenfu-Dongsheng mine area.According to simulation results,along with working face being advanced,the failure processes and features,and weighting of overlying strata,were analyzed.
