Abstract

The invention discloses a coal mine roadway with a water seepage warning function. An anchor net is fixedly arranged on the inner wall of the roadway. Two electrode plates are symmetrically arranged on the inner bottom wall of the water tank, and each electrode plate is slidably connected with a drainage bracket, and a rectangular groove is opened on the bottom wall of each electrode plate, and each rectangular groove has a Electrode sheets are placed, and each electrode sheet is connected to the corresponding drainage bracket through a traction rope. A drainage alarm mechanism is provided in the middle of the sump, and the drainage alarm mechanism includes an installation groove opened in the sump. The present invention can send an alarm in time when water seepage occurs at the surrounding rock above the roof, so as to warn the construction workers to plug the leakage and drain water in time. Long-term accumulation of water.

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...
