摘要
针对太原煤气化龙泉矿井4201综放工作面巷道的实际问题,提出了注浆加固的具体方案,即从工作面巷道布置及巷道围岩破碎情况的分析入手,对注浆参数进行了合理的选择。该注浆方案经实际实施,提高了破碎围岩的整体性和承载能力,从而保证了良好的加固效果。
To solve the practical problems of the 4201 fully mechanized caving area in Longquan coal mine of Taiyuan coal gasification company, put forward the concrete program of grouting reinforcement. Starting from the analysis of the roadway layout of the working area and the breaking of the surrounding rock of roadway, made reasonable choice of grouting parameters. The actual implementation of the grouting program improves the integrity and bearing capacity of the broken rock, so as to ensure the good effect of reinforcement.
