摘要
金川二矿区深部采场面积将达到10×10^4m2，埋深将接近1000m，因此，深部采场围岩及充填体的稳定性成为当前的核心问题。本文以金川矿区为例，针对由充填法开采引起的地表移动、变形和破坏等问题，分析了大量充填体形成的“人工岩体”、“空壳体”与天然地质体之间的性质差异及其相互作用机理，借鉴两体力学试验分析结果，提出了金川矿山深部开采面临的两体岩石力学问题。
Because in deposit 2 of Jinchuan Company,the deep stope area will reach 10×10^4 m2 and the buried depth will reach 1000 m, the key point is the stubility of deep wall rock and filling. This article for example, the current status of the ground movement, deformation and fracture induced by underground backfill mining in Jinchuan Mine No. 2 was given. , analysis of substantial fdling body formation of ＂artificial rock,＂ ＂empty shells＂ and natural geological differences between properties and their interaction, draw the bi - material model and the bi - body model test analysis, presented Jinchuan mines deep mining faces Bi - body Rock Mechanics.
