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。 The FLAC ~ 3D software was used to simulate the distribution of lateral bearing pressure on the island face, and the variation of plastic failure zone along the tilt direction was studied by radar detection. Through comprehensive analysis and comparison, the peak position of supporting pressure and the range of stress reduction zone were found out, which made the upper and lower lane sides of the working face successfully avoid the adverse impact of pressure peak area. The on-site practice shows that the condition of roadway maintenance is obviously improved, and the economic and technical benefits are remarkable.
