摘要
高阶段大直径深孔采矿法因其采场结构参数大、生产能力和效率高、成本低、作业条件安全、切割工程量小等优点被越来越多的矿山所采用。文章就该方法的现状及趋势做了一个简要的论述,并提出了一些存在的问题和措施。
High sublevel, large diameter and long hole stoping method is adopted by more and more mines because it has the ad- vantages of big stope structure parameters, large capacity and high efficiency, low cost, safe working conditions and small amount of cutting projects, etc. The status and developing trend of the method is outlined, some problems and their solving measures are put forward.
