根据采空区群分布情况,首先用高精度BLSS-PE矿用三维激光扫描测量系统进行精密探测,获得了105万m3大型采空区群,然后采用数值模拟软件FLAC3D计算分析该采空区群稳定性状况,模拟结果显示,间柱多发生塑性破坏,采空区群上下盘易发生拉破坏,存在大规模冒落危害,安全隐患突出.%According to the distribution of goaf group in a certain mine ,first of all ,the large goaf group of 10 500 000 m3 were detected using high-precision BLSS-PE ,and then the stability of goaf group was analyzed with numerical simulation software-FLAC3D.The results show that ,the plastic damage areas of the many pillars existed ,and the hanging and lower walls on the goaf group tensile damage occurred .These damage areas were a potential safety hazard ,and easy to occur mass caving .
