A high-pressure grinding material jet flow drill carriage device comprises a track travelling mechanism and a drilling machine, wherein an operating platform, and a high-pressure pump station, a water tank, a grinding material device and a high-pressure water braid device which are sequentially connected with one another through hydraulic pipes are arranged on the track travelling mechanism; the drilling machine is arranged in the front of the high-pressure water braid device; the tail end of a drilling rod on the drilling machine is connected with the high-pressure water braid device; a grinding material jet flow drill bit is arranged at the front end of the drilling rod; the grinding material device comprises a grinding material box and two brackets; the two brackets are arranged in the grinding material box in parallel; and grinding material tanks are arranged in the two brackets. Grinding materials and high-pressure water are mixed in the grinding material tank in a pre-mixing mode to form uniform mixed liquid, and the uniform mixed liquid is conveyed to the drilling rod through the hydraulic pipe and ejected at high speed through the grinding material jet flow drill bit to form grinding material jet flow with extremely high speed so as to coordinate with the grinding material jet flow drill bit to drill. The high-pressure grinding material jet flow drill carriage device is simple in structure, good in cutting and drilling effects and low in cost, does not induce gas explosion and avoids pollution.
Description
technical field [0001] The invention relates to a jet drilling device, in particular to a high-pressure abrasive jet drilling device suitable for the technical field of mining and drilling. technical background [0002] In the coal mine and stone industry, roadway mining, roadway excavation, coal mining roadway support, rock mining, etc. all require drilling of rock or hard minerals for special purposes. For example, it is used for the advance drainage of gas in the tunnel excavation of the underground mining face, and the gas drainage of the working face is carried out by using the tunnel; it is used for the prevention and control of coal seam rock burst and other geotechnical engineering construction drilling and pressure relief rock breaking. In the tunneling of underground coal mine roadways, it is necessary to drill holes without damaging the rocks in the roadway. Because there are many flammable and explosive gases underground, and the space in the underground roadway ...
