绳锯切割矿石在湖南衡阳七里井芒硝矿地下开采的实践与运用

Practice and Application of Wire Saw Cutting Ore in Underground Mining of Mirabilite Mine in Qili Well,Hengyang City,Hunan Province

全国芒硝矿地下开采仅有四川和湖南衡阳七里井芒硝矿,衡阳七里井芒硝矿开采成本比四川芒硝矿开采成本高,并且受地理环境影响,衡阳七里井芒硝矿采用绳锯切割在矿山井下开采中有效地降低了生产成本。

There are only Hengyang Qili Well Mirabilite Mine in Sichuan and Hu’nan in the country.The mining cost of Qil Well Mirabilite Mine in Hengyang is higher than that of Sichuan Mirabilite Mine,and is affected by geographical environment.The production cost of Mirabilite Mine in Qili Well in Hengyang was effectively reduced by rope saw cutting in underground mining.
