| 摘 要： | 金属矿山急倾斜薄矿体的开采因其赋存条件一直受到制约,贵州华金丫他金矿原采用留矿采矿法开采此类矿体时面临着资源回收困难,采矿效率差,采场经济技术指标不理想的问题.本文针对丫他金矿急倾斜薄矿体的开采技术条件和开采遇到的难题,提出上向水平分层充填采矿法并在矿区进行采场试验.试验采场应用效果良好,经济技术指标得到显著提升,为同类矿山开采提供借鉴思路.

| Abstract: | The mining of steeply inclined thin ore body in metal mines has been restricted by its occurrence conditions.When the stope mining method was used to mine such ore body in Huajin Yata gold mine,Guizhou Province,it was faced with the problems of difficult resource recovery,poor mining efficiency and unsatisfactory stope economic and technical indexes.In view of the mining technical conditions and difficulties encountered in the mining of the steep thin orebody in Yata gold mine,this paper puts forward the upward horizontal cut and fill mining method and carries out the stope test in the mining area.The application effect of the test stope is good,and the economic and technical indexes are significantly improved,which provides a reference for the mining of similar mines. |
