摘要
在四川某铜矿采用常规浅孔留矿法回采厚大急倾斜矿体过程中,对采矿技术方面存在的问题进行了深入研究与分析,得知造成矿山高贫损及生产秩序混乱的根本原因是缺乏一套合理的适用于厚大急倾斜矿体的浅孔留矿法回采技术,针对不同的问题提出了相应的改进措施,继而在矿山进行了现场试验并取得较为理想的效果,最大限度提高了矿石回采率,降低了贫化、损失,同时为相似条件的矿山提供了有价值的参考依据。
Analysis of the deficiencies and problems for mining technology in the process of mining the thick steeply inclined ore- body in a copper mine in Sichuan by the conventional short-hole shrinkage method showed that cause of the higher ore dilution and the production disorder is lack of a set of appropriate mining technology of short-hole shrinkage method for the large and thick steeply inclined orebody. The corresponding improvement meas- ures were put forward to address these problems and the subse- quent tests on the mine site were conducted with satisfactory re- sults obtained, maximizing the ore recovery rate and reducing the dilution loss, which could be provided as a valuable reference for the mines with similar conditions.
