巷旁充填沿空留巷技术及矿压显现规律

Technology of roadside packing in gob-side entry retaining and law of rock pressure

本文从充填材料、充填体支护参数、系统布置及充填工艺等几个方面对巷旁充填沿空留巷技术进行了研究与实践,通过控制充填材料承载特性和变形性能,改进了充填工艺,并对巷旁充填沿空留巷段进行了矿压观测,分析了巷旁充填沿空留巷及充填体的变形及受力情况。结果表明:巷旁充填沿空留巷技术能够有效地保证顶板的稳定性及完整性,充填体能够达到控制顶板下沉、适应顶板活动规律的要求。

Aimed at the technology of roadside packing in gob-side entry retaining,the filling materials,the choice of supporting parameter in roadside packing,and the optimizing of filling technics and arraying system were studied and practiced.Through controlling the characteristics of transmutation and load of the filling materials,filling technics were improved,and the rock pressure of gob-side entry retaining was monitored,transmutation and load of the fillings were analysed.The results reveals that the technolog...
