Abstract

In the mining process in Wu11 Coal Seam of the 10th Coal Mine,the gob water brought to the safety threat of flooding.The problems of gushing(suoden) water generally existed at the mining face.By analyzing the hydrogeological conditions of the mine,the measures taken in the mine water exploration gob are introduced.The technical guidance is provided for safety in production at the mining face.
