摘 要:平巷掘进作为当前矿山开采常常采用的一种技术,对矿山开采效率和开采质量有着重要影响。但是就当前矿山平巷掘进技术运用现状来看,依旧存在着技术运用不合理、缺乏必要的运用参数等问题,这就影响了整个矿山平巷掘进的效率。为此本文主要就矿山平巷掘进现状及改进进行分析,希望能够为矿山开采提供帮助。As a technology often used in mining,drift driving has an important influence on mining efficiency and mining quality.However,in terms of the current situation of mine drift driving technology,there are still problems such as unreasonable technology application and lack of necessary application parameters,which affect the efficiency of the whole mine drift driving.For this reason,this paper mainly analyzes the current situation and improvement of mine drift driving,hoping to provide help for mine mining.
