中文摘要：
以某矿倾斜＂三软＂煤层地质采矿条件为基础,以FLAC2D数值模拟分析为主要研究方法,模拟工作面开采过程,研究工作面周围岩体应力分布规律和倾斜方向工作面下边缘煤体30 m范围内岩体应力分布规律,为下一区段工作面回采巷道合理位置选择提供依据。
英文摘要：
Tilt a mine based on the ＂three soft＂ coal seam geological and mining conditions, on the basis of FLAC2 Dnumerical simulation analysis as the main research method, the simulation of working face in mining process, the surrounding rock stress distribution rule and the lower edge of the tilt direction of working face coal 30 m within the scope of stress distribution of rock mass. The next section in the design of return air along the trough, this roadway driving along goaf in 3 -5 m small roadway protection coal pillar is feasible and effective, for the next section provides the basis for reasonable mining face roadway location choice.
