在煤矿使用炸药引起灾害的主要原因有异常爆破、爆炸残留物的燃烧(着火源为瓦斯、煤尘爆炸等)或爆炸残留物复燃等。这些煤矿事故是由于某些原因导致爆破孔内炸药不能正常反应或正常的爆破受阻以及本来应该用于破碎围岩、煤的炸药能量向爆孔外传播而引起的。
The main causes of disasters caused by the use of explosives in coal mines are abnormal blasting, burning of explosive residues (ignition sources of gas, coal dust explosion, etc.) or explosive remnants of fire. These coal mine accidents were due to some reasons that the explosives in the blasting hole were unable to react normally or that normal blasting was blocked and that the explosives that would otherwise have been used to crush the surrounding rock and coal were caused to propagate outside the blasting hole.
