摘要
Abstract
In the caving mining process of 3 lower seam using full-seam mining, often encountered the roof maintenance dififcult because of the thinner gangue layer between the lower and the upper of NO.3 coal seam in the process of mining. This paper introduces pre-grouting reinforcement material to reinforce 3 upper coal collapse zone, which can be used for reference for similar mine.关键词
