Method and device for detecting water flowing fractured zone

The invention relates to the technical field of coal mine water flowing fractured zone detection, in particular to a method and device for detecting a water flowing fractured zone, and aims to solve the problems that a device for detecting the water flowing fractured zone in the prior art is prone to loosening in a drill hole and the drill hole is blocked and cannot enter the drill hole. The device comprises a fixed cylinder and a conical head installed at the head of the fixed cylinder, the fixed cylinder is provided with a water injection area and a non-water-injection area, a plurality of water outlet holes are formed in the periphery of the part, located in the water injection area, of the fixed cylinder, a partition plate used for separating the water injection area from the non-water-injection area is installed in the fixed cylinder, and a water conveying pipe is installed in the fixed cylinder. And the conical head pushes away the soil at the blocked part in the advancing process. According to the inve
