摘　　要：磷矿灾害动力学问题、安全问题一直是备受关注的重要难题之一。通过对宜昌矿区现场的工程勘查和取样测试、相关矿岩物理力学参数的收集、矿区地质情况及开采结构参数的调研、空区采场地压活动特征及规律的研究,查明了地压活动的主要控制因素,提出了基于模糊物元法的地压综合稳定性评价方法,并结合工程实际评价了采场各分区的稳定性。评价结果与实际吻合,为磷矿地压的安全性研究提供了有益的参考。The disasters dynamics and security of phosphate was one of the important problems in Phosphorus ore-deposit mining.Based on the site survey and engineering test in Yichang Phosphorus,the collection of physical and mechanical parameters for ore,the research of mine geological conditions and mining structural parameters,the characteristics and the activities laws of ground pressure,the main controlling factors of ground pressure were identified.The fuzzy matter-element model of stability evaluation on ground pressure in empty areas was built and the stability of underground mining partition was analyzed combining practical projects.The evaluation results are consistent with the actual values,which provide some useful reference for the pressure safety study in phosphate rock mass.
