Research and Development of Mining Wired Drilling Measurement System

Measurement while drilling (MWD) is a commonly used directional drilling technique that can measure the inclination angle, azimuth angle, tool face angle and other parameters of the borehole in real time and intuitively, making it easy for drilling personnel to monitor the drilling situation in real time. It can also adjust the inclination angle and process parameters of the drilling tool according to the design trajectory. The explosion-proof computer has been miniaturized, three commonly used measurement-while-drilling computers have been combined into one, and the transmission distance of the wired system has been increased. This article introduces the working principle of the underground wired drilling measurement system in coal mines. It elaborates on its composition and function from two parts: the measurement short section and the borehole computer. The system is tested and the results show that it meets the requirements of directional drilling.
