基于AHP权重的岩巷钻爆法掘进进尺影响因子分析研究

Analysis Study on Factors Affected to Heading Rate of Drilling and Blasting Method Applied to Mine Rock Roadway Based on AHP Weight

岩巷掘进进尺水平不高对煤矿建设和生产有很大影响。针对岩巷钻爆法掘进进尺影响因子的判断以定性为主的问题,把岩巷钻爆法掘进施工分为水文地质、凿岩、爆破、支护等八大部分,运用层次分析法,对掘进进尺影响因子对进尺的影响程度进行定量判断。结果表明,岩巷钻爆法掘进进尺八大影响因子中,主要影响因素是爆破技术及效率,其次是组织管理和排矸。

A low heading rate level of a mine rock roadway would have great influences to the construc- tion and production of the coal mine. According to the judgement of the factors affected to the heading rate of the drilling and blasting method applied to the mine rock roadway was based on the qualitative as the main problem,the heading construction with the drilling and blasting method could be divided into eight sections of hydrogeology, rock drilling, blasting, support and others. The analytical hierarchy process （AHP） was applied to the quantitative judgement on the influence factors of the heading rate affected to the influence degree of the heading rate. The result showed that in the eight major factors of the heading rate with the drilling and blasting method applied to the mine rock roadway, the main influence factors would be the blasting technology and efficiency and the second would be the organiza- tion management and waste rock discharging.
