矿柱回采方案的优化与实践

Optimization of orepillar stoping scheme and its application

针对陕西太白黄金矿业有限责任公司12 0 0m中段矿柱回采方案进行技术上研究,应用模糊数学的方法对落矿方案进行了优化选择,运用现代爆破理论对爆破参数进行了优化,采用分区多段同排的微差爆破新技术,成功地解决了厚大矿体矿柱难回采的问题。实践证明,该方案安全上可靠、技术上可行、经济上合理,取得了显著的社会效益、经济效益。

The orepillar stoping scheme is studied to the orepillar at depth 1 200m,the caving scheme is optimized with fuzzing mathematics,the blasting parameters are optimized with modern blasting theory,and block short-delay blasting technique is accepted.Therefore,the problem of stoping heavy orebody and orepillar was solved.The practice indicates that this scheme is safe,feasible and economical,and has made notable social benefits and economical benefits.
