Description

Technical Field

[0001] This utility model belongs to the field of open-pit mining technology, specifically relating to an auxiliary tool for measuring the location of blast holes. Background Technology

[0002] After the drilling rig in open-pit mining completes drilling, the location of the blast holes needs to be measured. The obtained measurement data must be provided to the blasting technician to provide technical parameters for subsequent blasting operations. Inaccurate measurements will directly affect the blasting quality. Because there are no specialized measuring tools available, it is impossible to measure the center of the blast hole; measurements can only be taken near the hole. This results in inaccurate measurement data, which in turn affects the blasting data.

[0003] In view of the above factors, this utility model provides an auxiliary tool for measuring the position of blast holes, which can effectively achieve accurate measurement of the position of blast holes, provide accurate technical parameters for subsequent blasting operations, and thus improve the quality of blasting.
