贵州汞矿梅子溪坑口的岩山坝矿段由三层矿体组成,按自上而下的顺序,CI 层矿体为自然汞与辰砂混合矿石,CⅡ、CⅢ层矿体为单一辰砂矿石。矿体的连续性以 CI 矿体较好,几乎沿走向都见矿;CⅡ、CⅢ矿体呈不连续的透镜体存在。矿段用平峒开拓,浅眼留矿的全面采矿法,按后退式顺序自上而下分层回采。本文根据我矿的实际情况,对含自然汞矿体开采的防毒问题谈几点意见,不当之处请同行指正。
The rocky dam section of Guizhou Hg mine plum stream pit mouth is composed of three layers of ore body. According to the order from top to bottom, the ore body of CI layer is a mixture of natural mercury and cinnabar ore, while the CⅡ and CⅢ layer ore bodies are single cinnabar ore. The continuity of ore body is better with CI ore body, almost all along the direction of the mine; C Ⅱ, C Ⅲ orebody is discontinuous lens body exists. Mining section with flat 峒 open-pit, shallow-eyed mineral mining comprehensive mining method, according to the order of retreat top-down stratified mining. Based on the actual situation of mine, this article talks about the anti-virus problem of mining natural mercury ore body.
