摘要
通过分析大店沟金矿多层矿体目前开采存在问题与现状,提出了4种技术上可行、经济上合理的采矿技改方案,对各方案在安全、效率、效益等方面进行了对比分析,最后确定推荐电耙出矿上向水平分层充填采矿法取代现有的浅孔留矿法,技改完成后,矿山净利将提升1倍,抗风险能力也明显增强。
Through the analysis on the existed difficulties and current situation of mining multi-layered deposit in Dadiangou gold mine,four mining schemes were proposed with technical reasonability and economic feasibility. By comparison on safety,efficiency,benefit and other aspects, the existing short-hole shrinkage method was replaced by the upward horizontal slice stoping and filling with drawing by scraper. After the technical optimization,the net profit had doubled up and the risk resistance capacity had been enhanced obviously.
