摘要
从介绍中国目前2座黄金矿山开采现状出发，分析研究了国内外金属矿山深井开采采矿方法可行性技术现状；单从采矿工艺与岩爆发生的关系方面来看：空场采矿法不可取，崩落采矿法也只能在一定深度范围内使用，唯一可以在深度2000～3000m以下的急倾斜或缓倾斜矿体开采应用的采矿方法，只有充填采矿法，而且是胶结充填采矿法；其充填率或充填密度越大和充填质量越高，对降低可以引起岩爆的能量耗散率有非常明显之影响。
The paper introduces the mining situation in two domestic gold mines, and analyzes the feasible methods for deep shaft metal resources mining at home and abroad. Considering the relationship between mining technique and rock burst only, the open stope mining method is inadvisable and the stoping-and-caving system can only be used in a limit depth. The only suitable mining method for steeply or gently inclined ore body at 2 000-3 000 m underground is cemented filling method. The higher the filling density or quality is, the higher the energy dissipation rate of rock burst is.
