As we enter the stage of intelligence, the comprehensive mining intelligent system is based on the hydraulic support electro-hydraulic control system. By improving perception, transmission and intelligent control capabilities, it achieves adaptive control goals and realizes unmanned coal mining. Huofeng has developed a low-cost North-seeking instrument that can be used to coal-loaded directional drilling airport scenes, accurately control the azimuth angle of the drill bit, and achieve precise operation; small North-seeking instruments are also maturely used in mining intrinsically safe drilling rig opening directional instruments, which is a new intelligent portable instrument for measuring the attitude of the drilling rig. The instrument uses an optical fiber gyroscope to measure the azimuth angle and inclination angle of the drilling rig, and accurately locates the drilling rig.
