Method for arranging concentrated draining lanes of working face floor

Abstract

The invention discloses a method for arranging concentrated draining lanes of a working face floor. The method comprises the following steps that firstly, according to the coal seam structural situation, the concentrated draining lanes of a working face are arranged in floor rock along the lowest part of coal seam, double lane arrangement is adopted, one lane is connected with a return airway of amining area, and the other lane is connected with an entrance of a water sump; and water draining drill holes are formed in the intersections of roadways on both sides of the working face and the concentrated draining lanes of the working face floor, gushing water in the working face or a goaf is gathered to the lowest part of the working face by gravity, the gushing water is drained along the water draining drill holes to the draining lanes, and finally the gushing water automatically flows to the water sump along the concentrated draining lanes of the working face floor. The method fully utilizes structural features and simplifies the layout of the draining lanes, a set of draining lanes is centrally arranged in the coal seam floor to serve the entire mining area, the system is simple and reliable, the production environment of the coal mining working face is greatly improved, the disaster resistance of a mine is improved, the amount of dredging in a ditch and the water sump is greatly reduced, favorable conditions for high-yield and stable production of the mine are created, and a good application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of mining engineering, and in particular relates to a method for arranging a concentrated drainage lane on the floor of a working face. Background technique [0002] The key to mine water disaster control is not only to ensure that the mine has a perfect drainage system, but also to ensure the unobstructed, stable and reliable drainage channels from the working face and the goaf to the water tank. [0003] Arranging special drainage lanes in the mining (panel) area is often the main method to solve the drainage of water gushing in the working face of mines with complex hydrogeology or extremely complex mines and goafs. At present, in order to solve the problem of large water inflow at the working face, when laying out the monoclinic coal seam, the mining (panel) area is often arranged as an overhead mining, and a special drainage lane is set for each working face to let the water gushing along the working fa...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provides a method for arranging centralized drainage lanes on the floor of the working face, which is aimed at mines with a large amount of water, and a centralized drainage lane (connected to the bottom of the working face) is set along the lowest part of the coal seam water tank and working face), serving the entire mining (panel) area, to solve the problem of water gushing and drainage in the working face and goaf, and realize safe mining

In this way, the problems of large engineering quantity, high investment, poor stope environment and safety in the layout of the traditional drainage roadway are avoided.
