| 摘 要： | 沿空留巷技术是煤炭开采技术的一项重要改革,是"绿色开采"的重要研究方向之一,针对试验矿井的5312倾斜工作面的具体条件,提出采用冒落矸石注浆固化沿空留巷方法,对巷旁支护阻力、冒落矸石冲击力和充填体可缩量预计进行了研究,通过现场观测和留巷效果分析,达到了预期的目标,能够为类似条件下的沿空留巷技术提供借鉴。

| Abstract: | Gob-side entry filling retaining technology is a major reform in coal mining technology and important research direction of coalmine "green mining".According to the specific site conditions of5312 inclined working face of experimental coalmine,the falling rock grouting gob-side entry filling retaining technology was proposed,the roadside support resistance,falling rock impact force and filling body shrink quantity was researched,the goal was attained by the analysis of field observation and effect analysis,it can provide reference for coal mines which in similar conditions. |
