Background
The coal mine tunnel excavation is the work of excavating wells, tunnels and chambers with various shapes, sections or criss-cross in a rock (soil) layer or a mineral layer. The tunneling process is divided into a main process and an auxiliary process. The main procedures are the procedures of ensuring the progress of the working face and the supporting operation in the roadway driving area directly completed on the working face. The main process is determined by the nature of the rock through which the roadway passes. When hard rock is tunneled, the main procedures comprise drilling, charging, blasting, ventilation, safety inspection of a working face, rock loading and roadway support; basic working procedures for tunneling soft rock comprise: digging, loading and supporting rock. If the method of adopting pneumatic pick, combination machine etc. is excavated, the excavation operation has the characteristics of continuous operation.

Particularly, the underground large-diameter deep hole blasting technology is widely applied to underground metal mines, so that the quality of the drilled hole plays a decisive role in the blasting effect. For deep blast holes, the drilling error of the rock with high strength can be controlled within half a meter; but rocks of low strength are likely to be displaced by one or two metres. If the position of the blast hole deviates too much from the design requirement, the direction and the size of the resistance line of the blast hole are changed, so that the blasting parameters such as hole pitch, row pitch and the like are changed, a large amount of large blocks and flying stones are generated, and the blasted working face is rugged.
In the existing means, the drilling position is determined by subjective experience of workers, so that potential safety hazards caused by insufficient blasting drilling precision are avoided.

The range of sensor operation is 90 ° ± 45 °, in which the probe can be arranged upwards or downwards, if it exceeds 90 ° ± 45 °, the probe will return the reading to "zero", and the probe is self-powered;
step two: the data are transmitted to an external control device through a signal transceiver, the control device analyzes the received signals and then transmits instructions to a corresponding linear driving device on the equipment, a port with a computer mark on the CDU is connected to the control device, and the data are downloaded from a probe to a serial port of the computer through the CDU;
step three: the alignment position of a drill bit (8) on the drilling equipment (7) is adjusted and determined through a linear driving device on the equipment, so that the automatic positioning function is realized, and the function of controlling a display unit in the control device is to record the time of each probe for measurement and record data.
