新城金矿深部采场现有支护方式合理性验证

在采矿工艺和地质构造的影响下,以新城金矿的开采技术条件,采场顶板局部稳固性差,且较破碎,从而局部或大面积顶板冒落事故发生的可能性变大,一旦发生类似事故,将会造成很大的矿石损失与贫化,同时会严重的威胁到采场工作人员的生命安全。基于上述分析,在矿山开采过程中,为了要实现安全生产,必须要对采场顶板实施支护控顶,以防顶板冒落事故的发生。

Reasonableness Verification of the Existing Support Ways in Deep Mining Site of Xincheng Gold Mine

Under the influence of the mining process and geological structure and the technical conditions of Xincheng Gold Mine, the local stability of mining site roof is poor and is easy to crush, so the possibility of partial or large area roof caving accident becomes larger.Once the occurrence of similar accidents, it will cause great losses and dilution of ore, and also will seriously threaten the lives and safety of the staff. In order to achieve safe production and prevent the occurrence of roof fall accident in the mining process, the supporting of the mining site roof is necessary.
