英文摘要：

With the increase of the gob area, more and more water accumulated in the gob area. In order to remove the gob water in Lijiata Coal Mine, analysis was made on the formation of the main water inrush sources by using the strata analysis method and the estimated method of the water flowing fractured zone, and the gob water sources were found out. The series-buried pipes in the working face were used to remove the gob water, this thus solved the problem of the main water disasters and guaranteed the safe production in the mine.
