Abstract

The invention discloses a coal mine roadway with a water seepage warning function. The coal mine roadway comprises an anchor net fixedly arranged on the inner wall of the roadway; a top plate is supported by the anchor net through a supporting layer; a water collecting tank is arranged between the anchor net and the top plate; two electrode plates are symmetrically arranged on the inner bottom wall of the water collecting tank; each electrode plate is slidably connected with a drainage support, and a rectangular groove is formed in the bottom wall of each electrode plate; each rectangular groove is internally provided with an electrode sheet; each electrode sheet is connected with the corresponding drainage support through a traction rope; a drainage alarm mechanism is arranged in the middle of the water collecting tank; and the drainage alarm mechanism comprises an installation groove arranged in the water collecting tank. The coal mine roadway can give an alarm in time when the waterseepage problem occurs at the surrounding rock above the top plate so as to warn construction personnel to block leakage and drain water in time, and the coal mine roadway can automatically drain water when the construction personnel do not drain water and too much water is accumulated in the water collecting tank so as to prevent water from accumulating at the top plate for a long time.

Description

technical field [0001] The invention relates to the technical field of coal mine roadways, in particular to a coal mine roadway with a water seepage warning function. Background technique [0002] With the increase of mine mining depth, the leakage of groundwater has become one of the primary considerations for mining operators. At present, the problem of local leakage in surrounding rock water-rich areas has not attracted people's attention, and construction workers pay more attention to mine water permeability. , water inrush, water gushing and other problems, but the long-term local leakage problem, especially the roof leakage problem will also cause great harm to the mining equipment, ventilation system and lighting system, and with the increase of the leakage time, the roof’s Stability will also be greatly affected, and problems such as roof bulging and deformation, rock mass crack expansion, and roadway separation will occur. If leakage is not blocked and drained in ti...
