兖州矿业(集团)公司济宁二号煤矿通过对带压管路疏通施工工艺的研究,创造性地采用管路带压开孔疏通新工艺处理副井井筒排水管堵塞并获得了成功,随后又成功地运用在风井井筒泥浆管堵塞疏通处理上。该矿对中央泵房水仓和吸水井进行清淤时,发现由于煤泥和木屑等杂物含量较大,在中央泵房排水管路积淀了一定数量
Yanzhou Mining (Group) Company Jining No. 2 coal mine through the pressure on the pipeline to clear the construction process of creative use of pipeline pressure to open a new technology to deal with open pore pressure well plugging the drain plug blocked and successful, and then successfully The use of the shaft in the shaft mud pipe clogging to clear the deal. The mine dredging of the central pump house water and suction wells, found that due to the larger content of debris such as slime and sawdust, in the central pump house drainage a certain amount of sediment
