自然崩落采矿法在M739铁矿的应用分析

Application Analysis of Natural Caving Mining Method in M739 Iron Ore

根据M739铁矿矿体赋存条件,结合自然崩落采矿法的采矿特点,主要解决M739铁矿矿体破碎、巷道施工难度大的问题,同时放矿管理和地压控制是采矿过程中的一项重要内容,控制好各出矿川的出矿量,达到防止地压显现和降低贫化的目的,从而取得较好的经济效益。

According to the occurrence conditions of the M739 iron ore body,combined with the mining characteristics of the natural caving mining method,it mainly solves the problems of the M739 iron ore body fragmentation and the difficulty of laneway construction,while the ore drawing management and ground pressure control are important contents of the mining process,controlling the ore output of each ore stream,to prevent the emergence of ground pressure and reduce the dilution,so as to achieve better economic benefits.
