摘要
根据金山金矿缓倾斜中厚矿体赋存状况,进行了底盘漏斗中深孔落矿采矿法试验研究。详述了采矿方法回采工艺过程,通过采场结构参数优化、扩漏技术及多排同段爆破技术的应用,现场工业试验取得了较好的技术经济指标并达到了预期的试验效果。
On account of the conditions of Jinshan gold deposit with moderately inclined and moderately thick ore- bodies, a mining method with bottom ore chute and medium-long hole blasting was tested. This paper discusses the stoping process of the mining method in detail. Through optimization of the stope structure parameters and application of ore chute reaming and multi-row simultaneous blasting, the commercial tests got fairly good techno-economical indexes and achieved expected experiment effects.
