Abstract
The invention relates to a sandstone aquifer water desorption method. The sandstone aquifer water desorption method comprises the steps of 10, working face geology and hydrogeology are analyzed; 20, water-pumping drilling positions are distributed according to tunneling roadway construction conditions and mining area geological and hydrogeological conditions; 30, holes are drilled in the distributed water-pumping drilling positions, and casing pipes are inserted in the holes; 40, the casing pipes are connected with a vacuum pump, and water adhering to fractures and holes of a sandstone aquifer is sucked out by the adoption of negative pressure formed by the vacuum pump; 50, the drilled holes are sealed. According to the sandstone aquifer water desorption method, the mining area geology and the hydrogeology are analyzed, and the hydrogeological conditions, the water filling factors and the threatening degree of mining area coal seam exploitation are investigated to provide bases for discharge of the water in the sandstone aquifer; since the water adhering to the fractures and the holes of the sandstone aquifer is sucked out by the adoption of the negative pressure formed by the vacuum pump, it is guaranteed that a coal seam is exploited safely on the basis of not changing the design of an existing mine drainage system, the working environment is improved, and the tunneling speed is increased.
