Abstract

The present invention proposes a high-pressure water jet drilling equipment and construction method for bolt construction in mines. The equipment includes a working part and a control part, and the working part includes a casing and an injector arranged inside the casing and a propeller, the injector is used to inject high-pressure water flow to the target area to realize drilling, the propeller is connected with the injector in transmission, and is used to drive the injector to move back and forth, and the control part includes a water pump microcomputer and a high-pressure water pump , the water pump microcomputer is connected with the high-pressure water pump, and the high-pressure water pump is connected with the injector through the water inlet pipe. The invention synchronizes the drilling and hole cleaning, which improves the efficiency of anchor rod construction. Compared with the traditional metal drill bit drilling, the high-pressure water jet has the advantages of high drilling alignment, low drilling temperature, and drilling stability. Advantages of high quality and high security.

Description

technical field [0001] The invention relates to the technical field of bolt drilling, in particular to a high-pressure water jet drilling equipment and a construction method for bolt construction in mines. Background technique [0002] As the most basic part of roadway support in contemporary mines, bolts strengthen the roadway and surrounding rock together, restrict the rock and soil from the original body, increase the cohesion of rock and soil, and can well reduce the occurrence of mine accidents . The drilling methods used in modern anchor bolt construction include manual hand-held drilling and fully mechanized drilling. Drilling instruments mainly include electric drilling instruments, hydraulic drilling instruments and pneumatic drilling instruments. [0003] During the construction of bolts in the mine, the vibration generated by the use of metal drilling equipment can easily disturb the rock and coal seams, resulting in roadway collapse accidents. Huge drilling equ...
