摘要
针对试验矿井5203工作面的具体条件,提出采用矸石-石粉混凝土砌块沿空留巷方法,对充填体的强度、倾覆稳定性和纵向变形适应性进行了研究,通过现场观测和留巷效果分析,达到了预期的留巷目标。
According to the site conditions of 5302 working face of the experimental coal mine,the rock-mountain flour concrete block gob-side entry filling retaining technology was proposed. The strength,overturning stability and longitudinal deformation adaptability of filling body were studied. The goal was attained by field observation and effect analysis.
