Measurement-while-drilling device applicable to advanced geological prediction for mine roadway

Abstract

The invention discloses a measurement-while-drilling device applicable to advanced geological prediction for a mine roadway, which solves a problem that a medium wind pressure and medium depth hole light down-the-hole drill in the prior art cannot accurately master the rotating speed and the drilling speed of a drilling machine in drilling and blasting construction of an underground chamber. The measurement-while-drilling device comprises a driving motor, a reducer, a drilling rod, a first detection gear, a mounting bracket, a first rotating speed sensor, a first intelligent rotating speed digital display instrument, a placement box, a gear shaft, a second detection gear, a second rotating speed sensor and a steel ruler, wherein the second rotating speed sensor is connected with a second intelligent rotating speed digital display instrument; the steel ruler is provided with ruler teeth, the ruler teeth are meshed with gear teeth on the gear shaft, the steel ruler is horizontally arranged in the placement box, and the outer end of the steel ruler is connected with the tail end of the driving motor through a connecting piece. The measurement-while-drilling device is simple in structure, scientific and reasonable in design and convenient to use, can monitor the rotating speed and the drilling rod of the drilling machine and the drilling speed of the drilling machine in real time,and provides accurate data for accurately predicting detailed engineering geological conditions of a drilling area.

Description

technical field [0001] The invention relates to a measurement-while-drilling device suitable for advanced geological prediction of mine roadways. Background technique [0002] In the prior art, when the air-pressure medium-deep hole light DTH drilling rig is in the drilling and blasting construction of the underground chamber, the grasp of the drilling speed of the drilling rig in the drilling and drilling is all judged by the experience of the operator captain, and a set of accurate and accurate drilling rigs has not been formed. The efficient acquisition system of the drilling speed of the drilling rig cannot accurately grasp the drilling speed and the drilling speed of the drilling rig, so that the detailed engineering geological conditions of the drilling area cannot be accurately predicted. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a measurement-while-drilling device suitable for advanced geological pr...
