摘要
在应用分段崩落法开采中厚矿体中,沿脉进路的崩矿步距是影响矿石损失贫化的重要参数之一。本文基于崩落体、残留体与放出体的相符关系,提出了沿脉进路崩矿步距的优化方法,并用于弓长岭井下铁矿,取得了良好的实用效果。
Application of sublevel caving to mine medium thick ore body, the caving space of followingvein drift is one of the important parameters for ore Loss and dilution. Based on the relationship of Blasted ore body, Remnant ore body and draw body, the paper proposed the optimization method of the caving space in the following-vein drift . This method was applied to Gongchangling underground iron mine, and the good practical effect was achieved.
