However, due to the large amount of peat and other impurities in industrial wastewater, the peat deposited in the water tank of the mining area must be regularly dredged, otherwise the water tank in the mining area will be filled with peat and lose its water storage function
Regular dredging and maintenance of water tanks in the mining area are time-consuming and costly, which have a great impact on the production and profit of the coal mine

The invention discloses a goaf water seal precipitation discharge closed system for working face industrial wastewater. The goaf water seal precipitation discharge closed system is characterized in that a # closed structure is arranged in a second working face haulage gate and located outside one side of a mining stopping line and at the joint with a third working face air return connection roadway; a 2# closed structure is arranged at one end of a second working face connection roadway and is close to the joint with a second working face air return roadway; a 3# closed structure is arranged at the other end of the second working face connection roadway and is close to the joint with a second working face air return way; and a 4# closed structure is arranged at the end, away from the 3# closed structure, of the second working face air return way and located at the joint with a first working face haulage gate. The closed structures define a discharge water channel between a third working face return water sump and a mining area water sump, so that sewage can be precipitated and purified through a goaf, and the dredging frequency of the mining area water sump is reduced.
Description
technical field [0001] The invention relates to the field of fully mechanized mining in coal mines, in particular to a closed system for goaf water sealing and sedimentation discharge of industrial wastewater in working faces. Background technique [0002] The industrial waste water produced by the existing underground coal mines is generally led to the specially set water tank in the mining area by special drainage pipelines for storage, and the upper clear water can be reused after settling in the water tank in the mining area. However, due to the large amount of peat and other impurities in the industrial wastewater, the peat deposited in the water tank of the mining area must be dredged regularly, otherwise the water tank in the mining area will be filled with peat and lose its water storage function. Regular dredging and maintenance of water tanks in the mining area are time-consuming and costly, which have a great impact on the production and profit of the coal mine. ...
