During the blasting operation, there are often hazards such as broken stones, shock waves, and noise caused by the explosion. The broken stones can easily cause damage to personnel and equipment, so protection is required. The Chinese utility model with publication number CN215810509U discloses a mine blasting broken stone protection device. Although the utility model is connected between the protective frame, active protective net, protective plate, vertical plate, spring a, and spring b, in the process of protecting the impact of broken stones, the larger broken stones are filtered through the active protective net, and the impact force generated by the broken stones is repeatedly apportioned and reduced by springs a and springs b, which has a good buffering effect. However, the mine blasting rock protection device has the following disadvantages: (1) when multiple sets of protection plates are spliced ​​together to expand the protection range, there is a lack of splicing mechanism between the protection plates, which makes it easy for them to be uneven during protection and for gaps to exist between them, thus affecting the protection effect; (2) it is not easy to reinforce and support the protection plates, and when the protection plates are hit by strong impact from the rock, they will fall over, affecting their use and failing to achieve the expected effect.
