针对金厂峪金矿难采矿体的情况 ,采用了分两层逆向和顺向推进房柱采矿法 ,应用FLAC软件 ,模拟沿矿体走向和倾向分层开挖过程中的围岩应力分布规律 ,为回采过程中采场围岩稳定性监测和围岩稳定性评价提供了理论依据。
Aiming at the difficult mining of Jinchangyu gold mine, the method of advancing forward and backward the pillar and pillar mining was adopted in two layers. The FLAC software was used to simulate the stress distribution of surrounding rock in the process of stratified excavation along the direction and tendency of the ore body. This study provides a theoretical basis for monitoring the stability of surrounding rock and the stability of surrounding rock in the mining process.
