摘要
为消除采空区积水威胁,确保泊江海子矿113106工作面回采工作安全进行,科学分析113106工作面采空区积水情况及其威胁程度,通过测量两巷的标高,利用巷道存在高差,在辅助运输巷非采煤侧埋管、埋泵以及在辅助运输巷低洼点埋设排水管路等措施,结果表明:埋泵的排水量为12m^3/h,埋管的排水流量为93.15m^3/h。大大减少了工作面采空区积水,提高了113106工作面煤质,降低了煤炭含水量,实现了矿井综合效益的提升。
In order to eliminate the threat of accumulated water in goaf and ensure the safety of mining in 113106 working face of Bojiang haizi mine.Based on the scientific analysis of water accumulation in goaf of 113106 working face and its threat degree,through measuring the elevation of two roadways,it is found that the height difference exists in the roadway,measures such as burying pipe and pump in non mining side of auxiliary transportation roadway and laying drainage pipeline in low-lying point of auxiliary transportation roadway are taken,the results show that:the displacement of buried pump is 12 m^3/h,and the discharge of buried pipe is 93.15 m^3/h.It greatly reduces the water accumulation in goaf,improves the coal quality of 113106 working face,reduces the water content of coal,and realizes the promotion of comprehensive benefits of the mine.
