【摘要】 随着金川龙首矿开采的不断进行以及采区的不断下降,深部矿体开采的安全性是一个十分重要的问题。根据龙首矿的地质条件、开采技术条件及生产现状,依照矿山采用的下向六角形进路式采矿方法建立了三维模型,并利用数值模拟方法分析研究开采过程中上部充填体及围岩的稳定性,可为矿山的深部安全生产提供依据。更多还原

【Abstract】 For the mining area lowering continuously with unceasing development of mining,the safety of deep mining is becoming a very important problem in Longshou Mine of Jinchuan Company.In the view of the geological condition,the technical conditions and the present state of mining in this mine,the 3D model for the adopted down hexagon drift mining method is build,and the stability of upper filling and surrounding rock is analysed using numeric using numerical simulation method,so as to set bases for the safety product in the deep in this mine.更多还原
