A device and method for preventing clogging of a grouting pipe for grouting clay on a coal mine floor

technical field

The invention relates to the technical field of mining and mining, in particular to a device and method for preventing clogging of a grouting pipe used for grouting clay on the floor of a coal mine.

Background technique

The coal seam floor is the rock layer directly under the coal seam in the coal-bearing strata section of the normal sequence, and the coal seam floor is the underburden rock layer. The bottom plate formed by the soil of coal-forming plants and rich in plant root fossils is called root soil rock, also known as bottom clay. In the process of coal mining, the clay on the bottom of the coal mine is often transported through grouting pipes, but during the transportation process , Due to the characteristics of clay, clay is easy to cause blockage in the grouting pipe. The existing grouting pipe needs to stop working immediately after the conveyed clay is blocked, and dredge the inside of the grouting pipe, but the traditional dredging method is manual dredging. Because the clay is relatively stable after solidification in the grouting pipe, the strength of manual dredging is too low, and the use of brute force during the dredging process is easy to damage the inner wall of the grouting pipe, resulting in a low service life of the equipment. The outer wall of the grouting pipe is cleaned, and the surface of the equipment is polluted.
