Under the mine, a large amount of accumulated water is often found in the excavated old roadway and the cavity, which is called as old empty water. The old and vacant water is the main cause of mine flood accidents and belongs to the most difficult to control in the water disaster types of coal mines. The general treatment method is to set a safe water-proof coal (rock) column and use a water-detecting and water-discharging drill hole to detect and discharge water. At present, a water detecting and discharging drilling structure is that a hole opening section (0-10 m section) is a hole opening sleeve, and the rest section is a naked hole, namely the naked hole is an unprotected rock stratum hole. In the use process of the drilling mode, the problem of drill hole blockage exists, and the blockage reasons include the following two reasons: firstly, water is drained for a long time, soft rock layers (mudstones and sandy mudstones) on the walls of the bare holes are soaked by water and lose supporting capacity, and therefore hole collapse is caused to block the holes; and secondly, the bottom layer of the water accumulation area is more in silt coal slime, the fluid coal slime can flow away with water, but larger pieces of gangue and crushed coal can flow into the drill holes to block the drill holes when entering the drill holes. Aiming at the problem of hole blockage caused by the reasons, the traditional solution is that when the water quantity of the drilled hole is abnormally reduced, an organization worker uses an anchor cable and a drilling machine to dredge the hole, but the risk that water is suddenly flushed out to hurt the worker exists in the dredging hole of the anchor cable; the drilling machine is dredged and has the risk of buried drilling and hole collapse during secondary drilling.
