摘要
采用FLAC 3D建立分析模型,研究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.结合现场实测,获得大倾角煤层开采矿压显现规律,进而提供支护措施的指导.
Using FLAC 3D to build the corresponding analytical model, the maximum stress concentration factor, the characteristics of supporting the pressure in the plastic zone were studied in a different angle of the wall in front of the coal seam and mined - out area; combined with the field measurement of the specific production of mine, and laws of pressure behavior in the steeply dipping seam mining were obtained, which could provide guidance to the support measures.
