Trepanning orientation measurement device and method fixed on drilling machine

Abstract

The invention discloses a trepanning orientation measurement device and method fixed on a drilling machine. The drilling machine comprises a posture measurement module and a laser indication module; the posture measurement module is installed and fixed on a drilling machine guide rail; the guide rail is parallel to a drill pipe, so that measurement on the current inclination angle and azimuth angle of the drilling machine can be achieved; the laser indication module is installed and fixed at the center position of a drilling machine clamper. According to the device and method provided by the invention, the problems that in the prior art, a trepanning orientation device cannot be installed on the drilling machine to achieve accurate measurement of the full space and a trepanning orientationindication is lacked can be solved, the measurement error of the trepanning orientation device caused by surrounding vibration can be effectively reduced, and the measurement accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of hole orientation of an underground drilling rig in coal mines, in particular to a hole orientation measuring device and method fixed on a drilling rig. Background technique [0002] Gas and water damage are the two most important disasters in the process of coal mining and treatment, and drilling technology is one of the main means to control and detect gas and water damage in coal mines to ensure safe mining of coal mines. The main goal of the drilling process is to realize the directional drilling of the gas drainage hole and the water exploration hole according to the pre-designed trajectory, and directly reach the detection target. Therefore, the drilling accuracy of the drilling rig directly determines the consistency of the actual drilling trajectory following the pre-designed trajectory. [0003] At present, most coal mines realize the drilling rig hole orientation method including manual measureme...
