柿竹园钨锡钼铋矿采用分段空场法和连续阶段大爆破崩落法回采矿床中心富矿带,给周边资源及下部开采带了一系列的生产问题。针对该矿开采技术条件、塌落区处理、采空区探查、露采优越性、露天境界优化、地采转露采的必要性和紧迫性、项目投资及等相关问题进行了分析研究,得出地采转大露采能很好地处理塌落矿岩,规避地采安全隐患,实现周边资源安全、高效、经济回采及优化配矿的结论,建议企业尽早实施大露采采矿工作。
Shizhuyuan tungsten-tin-molybdenum bismuth ore using sub-step empty field method and large-scale blasting continuous large-scale caving mining center ore belt, to the surrounding resources and the lower part of mining with a series of production problems. In view of the technical conditions of mine exploitation, the treatment of slump area, the exploration of goaf, the superiority of open-cut mining, the optimization of open-air realm, the necessity and urgency of underground mining, the project investment and other related issues, Mining out of place to a large decontamination can well handle the slump ore, to avoid hidden dangers of mining safety, to achieve the surrounding resources safe, efficient, economic recovery and optimization of ore mining conclusion, it is recommended that enterprises implement the dew mining work as soon as possible.
