| 摘 要： | 急倾斜薄矿体露头附近开采时，常形成三角形不规则采场，采用普通浅孔留矿法回采存在一系列技术问题。针对杨广寨铅锌矿的具体情况，对采矿方案进行了优化，提出了矿房联络道通达地表的采准布置方案，并在矿山进行了采矿实验。结果表明，该采矿方法可减少大量采准工程，提高回收率及回采效率，降低采矿成本，具有较高的应用价值与经济效益。

| Abstract: | When extracting steeply-inclined thin orebody near outcrop,there normally exists triangle stopes.Many technological problems occur when extracting such stopes with common method of shrinkage stoping.The Paper optimized the mining method of Yangguangzhai Pb-Zn Mine and designed a scheme of room connection heading to the surface.The scheme was experimented in the mine and the result shows that it can reduce much job in mining preparation,increase recovery and extracting efficiency and cut down mining cost.It ... |
