摘要
本文根据矾山磷矿的矿体条件,提出了采矿方法选择中的主要问题。针对倾角缓、矿体水平厚度40～50m、矿体松软破碎、顶盘岩石中等稳固的特点,推荐用有底部结构分段崩落法电耙出矿的方案。
The paper addresses major considerations in selecting mining methods in the light of the conditions of orebudy. In view of the fact that the orebody,dipping gently with its horizontal thickness of 40～50m,features instablc and fractured ores and moderately stable hanging wall,the sublevel caving method with scraper drawing drift at the bottom of the block is recommended in the paper.
