摘要
采用FLAC^3D软件模拟了孤岛工作面侧向支承压力的分布规律,并利用雷达探测研究了塑性破坏区沿倾斜方向的变化规律。通过综合分析与对比,找出了支承压力高峰位置及应力降低区范围,使设计的工作面上、下巷位置成功地避开了压力高峰区的不利影响。现场实践表明,巷道维护状况明显改善,经济与技术效益显著。
By the comprehensive results of abutment pressure distribution simulated with FLAC^3D and fracture zone of surrounding rock detected by the ground radar, the peak and the decline area of abutment pressure in isolated coal pillar are determined. By successfully avoiding the high abutment pressure zone, the road position of the working face is chosen, and the support result is significantly improved.
