摘要
小康矿井田应力场是全球大区域应力场的一部分,由于断裂的影响,使得局部应力场与区域大应力场存在一定差异,通过有限单元法进行数学计算,分析探索原岩应力分布规律,确立主应力方向,为科学选择巷道位置,合理选择支护形式创造条件。
The well - off mine field stress field is the world＇s largest part of the regional stress field, due to the impact of fracture, the local stress field and stress field in the region there are some big differences, through the finite element method to carry out mathematical calculations, analysis to explore distribution of rock stress establish the principal stress direction, the location of roadway for scientific choice, reasonable choice to create conditions for the form of support.
