Abstract
The invention discloses a mining anti-deflection drill bit and a drilling method. The mining anti-deflection drill bit comprises a drilling tool connecting body, a drill bit matrix, diamond compact drilling tools and a guiding and positioning body, wherein the drilling tool connecting body is cylindrical, and a conical threaded through hole is formed in the axis of the drilling tool connecting body and used for being connected with a drill rod; the end of the drilling tool connecting body is connected with the drill bit matrix, and a positioning and guiding body mounting hole used for mounting the guiding and positioning body is formed in the axis of the drill bit matrix; the three diamond compact drilling tools are arranged on the drill bit matrix in a surrounding mode; and the guiding and positioning body is higher than the diamond compact drilling tools. The mining anti-deflection drill bit effectively solves the deflection problem in drilling construction for coal mine disaster control such as gas disasters and water disasters, and has the function of guaranteeing straight drilling.
Description
technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a mining anti-deflection drill bit and a drilling method. Background technique [0002] For the management of major disasters in coal mines, drilling is usually used for advanced management. Use boreholes to detect, control, and manage disaster sources, and achieve disaster management standards to meet safety production requirements. Therefore, drilling engineering is of great significance to the safety of mines with serious disasters. At present, there are many types of drilling engineering equipment and tools commonly used in mines, with different advantages and disadvantages, but they all have the problem of drilling deflection, especially in the construction of medium-deep drilling, the drilling deviation causes the drilling construction to fail to meet the design requirements, resulting in Disaster governance blind spots. If supplementary measures are not take...
