[0002] Ore blasting is a commonly used method in mine exploitation. By controlling blasting parameters such as charge amount, charge position, and delay time, etc., the impact on the surrounding environment and equipment is minimized, while the ore exploitation efficiency is maximized. The background technique includes blasting design, selection of blasting devices, formulation of safety measures, as well as rock treatment and environmental protection measures after blasting, ensuring the safety, efficiency, and environmental friendliness of blasting operations;

[0003] The supports used in ore blasting play a key role in blasting operations. Equipment related to the supports includes drilling machines and explosive loading equipment. The drilling machine drives the drill rod and drill bit through a power device, rotates and drills blast holes in the ore, providing an accurate space and position for subsequent explosive placement. The explosive loading equipment precisely transports and fills the explosives into the previously drilled blast holes through a conveying device and a control device. The coordinated action of these devices ensures the efficient and safe progress of blasting operations;
