摘要
河台金矿床为急倾斜脉厚2.5～2.55m蚀变糜棱岩型金矿床,采用留矿采矿法和小分段中深孔崩落法开采。高村矿区由于采空区未得到有效处理,部分地段采空区已连片塌落,有的地方已塌穿地表,给生产带来很大负面影响。结合云西矿区的生产实际情况,介绍在云西矿区开展采空区处理的试验研究工作。
The mylonite -altered gold deposits have been exploiting in Hetai Gold Mine. Thrinkage stoping and sublevel caving are used for mining of steep veins with thickness of 2.5 - 2.55 m. Since Gaocun mining area is put into production in Jan. ,1989 ,the partial mined- out spaces have caving naturally and some of these spaces have opened up to surface because of irrational goal management. Therefore, this brings a great negative impact to production. In this paper, a research and test plan for the goal management is introduced according to the realities of Yunxi mining area.
