[0002] Mine blasting is a blasting operation carried out in a mine or mining scene, aiming to break rocks, release ores, control the moving direction of rocks, and improve mining efficiency. During mine blasting, in order to control the direction and scope of the explosion to maximize mining efficiency and protect the surrounding environment, directional blasting needs to be adopted. During the directional blasting process, it is necessary to first drill blasting holes. In order to prevent the blasting cylinder from slipping when it is inserted into the hole, a fixing device is usually used to fix the blasting cylinder.
