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。
Gob-side entry retaining technology is an important reform of coal mining technology and is one of the important research directions of “green mining ”. According to the specific conditions of 5312 inclined working face in pilot mine, Empty retaining lane method, research on roadside support resistance, impact force of falling gangue and shrinkage prediction of filling body were researched. Through on-site observation and effect analysis of retaining lane, the expected target was achieved, Retaining lane technology to provide reference.
