Drainage device for mine ventilation roadway

Abstract

The invention provides a drainage device for a mine ventilation roadway. The drainage device comprises a water collection well arranged in the roadway, a ditch is formed in the ground surface of the roadway to communicate with the top of the water collection well, a floating ball switch is arranged on the side wall of the water collection well, the water collection well communicates with a water pump through a pipeline, and the floating ball switch is connected with the water pump through a control system; and the floating ball switch comprises a floating ball, a floating rod, a mounting frameand a double-control switch and is fixed to the upper end of the side wall of the water collection well through the mounting frame. The drainage device adopts the structure that the ditch is formed in the ground surface of the roadway, thus the defect of local water accumulation caused by uneven ground of a roadway in the prior art is overcome, meanwhile, the floating ball switch adopts the structure that the double-control switch is arranged on the upper part of the floating ball, no complex circuit is arranged, thus the structure is simpler, operation is stable and reliable, the operation safety of mineral exploration can be guaranteed, the exploration efficiency is improved advantageously, and overall mounting and using are convenient; and the drainage device is widely suitable for being matched with drainage equipment for use.

Description

technical field [0001] The invention relates to drainage equipment, in particular to a mine ventilation roadway drainage device. Background technique [0002] Mineral resources are generally buried deep, and are mainly mined underground. During the mining process, a large amount of groundwater will inevitably gushes out. If the groundwater cannot be discharged in time, it will accumulate in the roadway, affecting the mining of underground mines. The safety of the mine cannot be guaranteed, and serious cases will cause well flooding accidents, which will bring huge personal and property losses; especially in the ventilation tunnels in mines, if there is too much water, when the fan is performing ventilation operations, it is easy to drain the tunnels. The accumulated water in the tunnel will cause the air humidity in the roadway to increase suddenly, and the operation of the fan in such an extremely humid environment will reduce the service life of the fan unit on the one han...
