[0002] Mining engineering mainly involves the exploitation of mining resources. Before mining construction, technical personnel are required to carry out targeted blasting. The compression, loosening and damage caused by the explosion can destroy the ore medium, making it easier to mine the ore. Before blasting, holes need to be drilled at the blasting site to facilitate the placement of explosives.
[0003] The existing non-drilling device cannot accurately locate the position of the drill hole, resulting in a certain deviation in the position of the drill hole, affecting the subsequent blasting effect. At the same time, after the existing drilling device is placed in the designated position, it is impossible to quickly and conveniently adjust the position of the drill bit, which reduces the use effect and efficiency of the entire device.
[0004] Therefore, we propose an adjustable pre-drilling device for blasting in mining engineering. Summary of the Invention
