脉状矿床开采维护矿山整体稳定性的一般原则和方法

General principle and method to uphold overall stability of mine in the mining of vein deposit

含金石英脉群类型的矿床，当采深达到一定程度而采空区又未进行适当处理时，矿山的整体稳定性应予以充分注意。可采取的措施和方法有：在采矿设计中，尽量改善采场围岩的应力环境；为防止岩移“突破口”的形成，处于某些关键部位的采场，应适当进行支护、充填或加固。

When the mining of gold-bearing deposit of quartz vein type reaches to a certain depth with mined-out area untreated, full attention should be paid to mine's overall stability. The improvement of stress environment of country rocks as possible as it can in the mining design, the proper support, the filling or reinforcement to the stope which is located in a key position so as to prevent it from formation of gap, of rock movement etc are suitable measures adoptable.
