三昌采石场采空区具有规模大、数量多、空间关系复杂等特点,急需开展复杂采空区群稳定性课题的研究.在对采空区群及其开采环境现场调研的基础上,进行了现场点荷载试验与室内单轴抗拉、抗压强度实验,获得岩体力学参数.采用三维有限元方法对三昌采石场进行数值模拟,模拟结果表明：三昌采石场采空区稳定性偏低,部分空区顶板出现拉应力集中,有可能出现顶板冒落.根据分析结果,提出了相应安全对策,为矿山的安全生产起到指导作用.

The goaf of San chang quarry has some characteristics of large scale and quantity,complex spatial relationships etc,so we to need to carry out a research about stability of complex goaf group.On the basis of investigating the goaf group and the mining environment,we performed the field point load test and indoor uniaxial tensile and compressive strength experiment,and obtained rock mechanics parameters.We simulated the complicated goaf group stability in San chang quarry by three-dimensional finite element method.The results are as follows：the stability of goaf in San chang quarry is low,part of roof on mined-out area appear concentrated tensile stress,and roof falling may happen.According to the results,we propose appropriate safety measures,which can play a guiding role in mine safety production.
