摘　　要：介绍了我国南方某黄金矿山采用无底柱分段崩落采矿法,对在开采生产中所遇到的各方面围岩稳固性问题,即矿床开采技术条件、地应力、覆盖岩层与井巷稳固性的关系进行了分析研究,以便于在今后矿山生产中,掌握并应用其规律,达到安全、高效、经济地开发矿产资源之目的。The problems of surrounding rock firmness occurred in mining when pillar-free sublevel caving mining method was used in a gold mine in the South of China. The relations between mining tech- nical conditions, ground stress and rock cap of deposit and mine workings firmness were analyzed so that related laws could be grasped and applied to develop mineral resources in a safe, high efficient and economic way in production in future.
