明佳克金矿6号井筒保安矿柱的矿量约60％是用松散充填料进行密实充填回采的,因此上部岩层以及被保护区的变形和错动逐渐增大,已接近极限许可值。残留的矿量或者使用具有所需强度特性和压缩特性的胶结充填法回采,或者是在拆除被保护物之后使用其它方法回采,如分层崩落法。为了论证地压管理的合理方法和选择经济合理的采矿
Approximately 60% of the mines of the No. 6 wellbore safety pillar in the Mingjijia Gold Mine are filled with loose fillings for tight filling. As a result, the deformation and misalignment of the upper strata and the protected areas gradually increase and are close to the allowable limit. The remaining amount of ore is either recovered by cementing with the desired strength and compression characteristics or by other methods such as cascade caving after removal of the protected object. In order to demonstrate the reasonable methods of geo-pressure management and choose economical and reasonable mining
