摘要
采用FLAC3D建立相应的分析模型,研究比较了不同倾角煤层煤壁前方和采空区倾向的最大应力集中系数、支承压力塑性区范围的特征;结合具体生产矿井的现场实测,获得了大倾角煤层开采矿压显现规律。
According to using FLAC^30 to build the corresponding analytical model, to study a different angle compared the wall in front of the coal seam and mined-out area of the maximum stress concentration factor, the characteristics of supporting the pressure in the plastic zone; com- bine the field measurement of the specific production of mine, and obtain Laws of pressure behavior in the steeply dipping seam mining.
