摘　　要：充填采矿法是一种回收率高、贫化率低、采矿成本比较高的采矿方法,本方法适用于矿岩稳定性差的贵金属地下矿床以及有特殊要求的矿床开采。采用充填采矿法的矿山,其采场地应力的分布与围岩的稳定状态,不仅与矿区的地质构造、原岩应力、矿岩质量等因素有关,而且还与充填体的强度、充填体的整体性和充填工艺等密切相关。充填体与围岩的应力分布,以及其最终稳定的状态取决于充填体与围岩的相互作用的结果。The backfill mining method is one kind method that is high returns--ratio, low impoverishment rate, high mining cost, this method is suitable to the precious metal subterranean deposit of bad ore--bearing rocks stability as well as ore deposit mining which has special request. The mine using the backfill mining method, its distribution of the stope crustal stress and adjacent formation steady state is related with mining area geologic structure, country rock stress and ore--bearing rocks quality, also is related with the intensity, integrity and backfill craft of filled body. The stress distribution of the filled body and adjacent formation and its final steady state is decided in the result of the mutual function of filled body and the adjacent formation.
