Water draining device of water sump in mining air way, and mounting method and working method of water draining device

Abstract

The invention discloses a water draining device of a water sump in a mining air way. The water draining device of the water sump in the mining air way comprises an electric pump, wherein the electric pump is provided with a water draining suspension device which is connected with the electric pump; the water draining suspension device comprises a suspension frame; the suspension frame is a rectangular grate; a suspension barrel is arranged at a gap of the grate; the part, which is close to the bottom, of the electric pump is connected with the suspension frame; the suspension frame is further provided with a guide rod assembly; and a switch of the electric pump is serially connected with a travel switch arranged on the guide rod assembly. The invention further discloses a mounting method and a working method of the water draining device of the water sump in the mining air way. According to the technical scheme, the electric pump is provided with the water draining suspension device which is connected with the electric pump, pump burning caused by the reason that the electric pump is blocked by sludge is avoided, meanwhile, operation of the electric pump is realized by the guide rod assembly, field monitoring of workers is avoided, and by unmanned water draining of the electric pump in a controlled manner, investment on underground labor and materials is relieved, and normal mining of a working face is ensured.

Description

technical field [0001] The invention belongs to the field of coal mining, and more specifically, the invention relates to a drainage device for a water tank in a mining wind tunnel, an installation method and a working method of the drainage device. Background technique [0002] The underground mining working face of the coal mine is affected by coal roof sandstone fissure water, borehole water, fault water, and coal floor limestone water, and the water inflow is relatively large. There are multiple water tanks, and each water tank is equipped with more than one electric pump. The electric pump drains water, and 24-hour on-site monitoring is carried out. Due to the large amount of coal slime in the sewage in the roadway, the sludge in the water tank settles quickly, which often leads to hanging In the water tank, the electric pump is blocked by silt and the pump is burned. Once the pump is burned, the electric pump must be replaced to ensure the normal mining of the working ...

[0002] The underground mining working face of the coal mine is affected by coal roof sandstone fissure water, borehole water, fault water, and coal floor limestone water, and the water inflow is relatively large. There are multiple water tanks, and each water tank is equipped with more than one electric pump. The electric pump drains water, and 24-hour on-site monitoring is carried out. Due to the large amount of coal slime in the sewage in the roadway, the sludge in the water tank settles quickly, which often leads to hanging In the water tank, the electric pump is blocked by silt and the pump is burned. Once the pump is burned, the electric pump must be replaced to ensure the normal mining of the working face. On-site monitoring by personnel and frequent replacement of the electric pump waste a lot of manpower and material resources, and a large number of personnel Stuck underground, exacerbating the hidden dangers of safe production
