Problems solved by technology

Therefore, in the process of blasting, it is difficult to check and clean each blast hole in the tunnel section before charging, and it is also difficult to quantitatively measure the actual blast hole depth. It is also difficult to ensure that each blast hole The installed charge structure in the deep hole fully complies with the designed charge structure, resulting in a low utilization rate of the blasthole, failing to achieve the expected rock breaking effect of drilling and blasting, and failing to obtain an ideal tunnel excavation surface
