Preventive measures for accidents caused by shotguns in metallurgical mines

After the deep hole blasting in the stope, a pile is formed. During the ore handling process, the angle of the pile is gradually increased. If the angle of the pile is too large and not treated in time, once the large ore is rolled off from the upper part of the pile, the miners can't dodge. It is prone to accidents involving rolling stones.

Preventive measures

1. Determine the angle of the explosion. According to the production practice experience, the explosion angle is safer at around 40 degrees, but the maximum is not more than 45 degrees.

2. In the mining operation, it is found that the explosion angle is too large to be treated in time, and the mine can continue to be mined when it is confirmed that the explosion has reached a safe angle.

3. Strengthen the safety inspection of the stope. The management personnel at all levels found that the explosion was too steep and risky production. They should immediately stop mining and deal with the explosion.
