摘要
浅孔留矿法具有生产工艺简单、生产工艺容易掌握等优点,比较适用于地处四川省矿山开采,将无底柱浅孔留矿采矿法与底柱留矿采矿法进行对比可以发现,无底柱浅孔留矿采矿法减去了矿块底部结构中的斗颈掘进工程和劈漏工程,有利于矿块底部掘进开采。
Shallow hole shrinkage mining method has the advantages of simple production process and easy mastery of production process,which is more suitable for mining in Sichuan Province.By comparing the shallow hole shrinkage mining method without pillar with the pillar shrinkage mining method,it can be found that the pillar-free shrinkage mining method can subtract the bucket-neck excavation project in the bottom structure of the block.And the split leakage project is beneficial to the excavation of the bottom of the ore block.
