高水材料巷旁充填矿压观测与研究

Field measurement and analysis of ground behavior of roadway retained by packing high water content material along goaf side

本文通过对翟镇矿高水材料沿空留巷巷旁充填矿压观测与分析可知，高水灰比（Ｗ／Ｃ＝２．５∶１）下，ＺＫＤ高水材料所构筑的巷旁充填带，能满足采面顶板活动规律要求，也能有效控制巷道围岩变形，可塑性好，韧性好，是一种理想的巷旁充填材料。

Abstract At Zhaizhen Colliery, a industrial test and field measurement of retaining roadway for next level by packing ZKD type high water content material along the goaf side is carried out. The water-cement ratio used in situ, W/C, is 2.5:1. The ZKD type material packed strip is effective to control the deformation of rock surrounding the roadway and satisfy the requirement of roof activity of working face. It fully prove that ZKD type material of good plasticity and ductility is perfect packing material beside roadway.
