摘要
在不考虑原岩应力条件下,运用FLAC3D软件分析预紧力锚杆在不同间、排距情况下对岩体施加应力场的影响范围。采用模拟手段对不同宽度的煤柱应力场进行仿真研究。通过研究选择合理的支护密度、煤柱尺寸,使围岩达到稳定状态。
Using the FLAC3 Dsoftware,without taking into account the original rock stress conditions,analysis of pre stress bolt applied range of influence of stress field of rock mass in different rooms,row spacing condition.Using simulation method is developed for the calculation of the stress field of different width coal pillars. Support density,the size of coal pillar support through the research of the reasonable selection of the rock reaches a steady state.
