富堡煤业一1煤层巷道在掘进过程中底板有突水危险,在掘进过程中遇断层和裂隙必然出水,遇水需注浆封堵,本文分析了该矿底板突水的可能性,介绍了奥灰水注浆封堵工程的必然趋势,针对注浆封堵工程采取了相应的措施,总结了施工结果,工程达到了封堵底板裂隙等导水通道的目的。
In the excavation process, the coal bed of a coal seam of Fubao Coal Mine 1 is in danger of water inrush during the excavation process. In the process of excavation, faults and cracks inevitably come out of the water and the water is required to be grouted and sealed. This paper analyzes the possibility of water inrush from the mine floor The inevitable trend of Ordovician gray water grouting project, taking the corresponding measures for grouting engineering, summarized the construction results, the project reached the purpose of blocking the aqueduct such as floor cracks.
