破碎顶板煤巷掘进的支护研究

Support Research of Driving in Broken Roof Coal Roadway

当前我国煤矿开采深度以及宽度日益扩大,同时开采条件日益复杂,不断向地质构造复杂区域延伸。随着我国煤炭需求量的不断增长,煤矿开采压力持续增加,受到煤层压力以及应力等诸多因素的干扰导致采煤巷道支护的选取以及实施更加的困难,尤其是破碎顶板煤巷掘进支护更是如此。基于此,本文主要对破碎顶板煤巷掘进的支护进行了有效的分析,以供参考。

At present,mining depth and width of coal mine in our country has been expanding increasing,and mining conditions have become more and more complicated,extending to area with complicated geological structure.With continuous growth of coal demand in China,coal mining pressure has been increasing.Under interference of coal seam pressure,stress and other fa ctors,it is more difficult to choose and carry on coal roadway support,especially driving support of broken roof coal roadway.On the basis,the paper analyzes support of broken roof coal roadway driving effectively for reference.
