缓倾斜含夹层中厚矿体的开采,无论是贫损控制还是地压控制.难度都比较大作者以贵州万山汞矿岩山坝矿段为实例,对此类型矿体作了研究由于该矿现使用一般的房柱法,存在严重矿石损失的问题对此,作者通过深入研究。提出矿房留矿矿柱崩落联合法、矿房空场矿柱崩落联合法及矿房崩落矿柱崩落联合法三种新方法。它们的贫损指标有了明显的改善,为这类矿床的开采探讨了一条有益的途径 The mining of moderately thick ore body with moderately inclined intercalation, whether controlled by loss or pressure control, is quite difficult. Taking the rocky dam section of Wanshan mercury mine in Guizhou as an example, this kind of orebody was studied. Now use the general method of housing, there is a serious problem of ore loss to this, the author through in-depth study. Three new methods are proposed, such as the coalmine ore caving method combined with coal mining, the joint mining caving method and the coal mining caving method. Their indicators of depletion have been significantly improved, exploring a beneficial approach to the exploitation of such deposits
