YHZ90/360 Mining Intrinsic Safety Drill Hole Directional Instrument

Product Introduction

The YHZ90/360 Intrinsically Safe Mining Drill Hole Directional Instrument is a newly developed portable hole directional instrument that uses high-precision gyroscopes to accurately measure the posture (azimuth and inclination angle) of the drilling rig. The measurement process does not involve the influence of ferromagnetic substances, overcoming the problem of inaccurate measurement caused by magnetic substances such as the drilling rig, steel mesh, and anchor rods in traditional geological compass measurement. It is also assisted by laser positioning to achieve precise positioning of the hole position, Effectively guide the positioning of underground openings.

The instrument has the characteristics of small size, light weight, convenient portability, and is not affected by electromagnetic and ferromagnetic materials. Digitally display the inclination and azimuth angle of the drilling hole, while also displaying the instrument's electricity, making it easy for operators to replenish their electricity in a timely manner.

Product Usage

This instrument is suitable for high gas, high dust, and high temperature environments underground in coal mines; Able to accurately measure the opening angles of vertical holes, horizontal holes, depression holes, elevation holes, geological exploration holes, gas drainage holes, exploratory water holes, grouting reinforcement holes, and other drilling holes.
