摘要
采矿人员根据扩充直接顶板的厚度与稳固性以及缓倾斜锰矿矿体的实际变化特点,研发出不同类型的采矿方法。本文将对传统锰矿矿体的开采方法进行概述,分析传统采矿方法存在的主要问题,探究不稳围岩缓倾斜薄矿体的采矿方法。
According to the thickness and stability of expanded direct roof and the actual change characteristics of gently inclined manganese ore body,mining personnel have developed different types of mining methods.This paper will summarize the mining methods of traditional manganese ore body,analyze the main problems of traditional mining method,and explore the mining method of gently inclined thin ore body with unstable surrounding rock.
