摘要：
以高家梁煤矿20306工作面地质条件为依托，采用多点位移计、锚杆（索）测力计和钻孔应力计相结合对联络巷及煤柱变形及应力分布规律进行检测，并采用UDEC软件模拟不同区段煤柱宽度时辅运顺槽变形及应力分布情况。结果表明：20306工作面超前支承压力峰值位置位于前方20~30m，侧向支承压力峰值位置距煤壁约22m，合理的区段煤柱宽度为12m左右。
关键词: 近浅埋煤层, 侧向支承压力, 煤柱尺寸, UDEC
Abstract:
As the background of geological conditions of 20306 coal face in Gao Jialiang Colliery, multi-bases displacement monitoring device, anchor dynamometer and borehole stressmeter were used to detect deformation and stress of contact Lane and coal pillar, and UDEC was used to simulate distribution of deformation and stress in surrounding rocks of service gate with different coal pillar size. The results show that the peak of advanced abutment pressure is 20~30m ahead, the peak of side abutment pressure is about 22m away from coal wall, and the width of coal pillar should be 12m.
Key words: Near shallow seam, Side abutment pressure, Coal pillar size, UDEC
