炸药爆炸后生成炮烟,其主要成份有:CO、CO_2、H_2、NO、HCN、CH_4、NH_3、SO_2、NO_2、H_2S等。炮烟危害人体健康,地下爆破时更为严重。 根据实验报告,通常一公斤工业炸药爆炸后,生成炮烟气体350～1000升,其中有毒有害气体60～150升。国家规定一公斤炸药爆炸后产生有毒有害气体不得超过100升,方可用于井下爆破作业,同时强调,井下爆破后须通风三十分钟(如露天爆破,须经十五分钟)后,才许工作人员进入现场检查。否则,会发生炮烟中毒事故。
The explosives generated after the explosion of gunfire, the main ingredients are: CO, CO_2, H_2, NO, HCN, CH_4, NH_3, SO_2, NO_2, H_2S and so on. Barrels of smoke endanger human health, underground explosion more serious. According to the experimental report, usually one kilogram of industrial explosives after the explosion, resulting in 350-1000 liters of gunfire gas, toxic and harmful gases which 60 to 150 liters. The state stipulates that the poisonous and noxious gas generated after explosions of one kilogram of explosives shall not exceed 100 liters before being used for downhole blasting operations. At the same time, it is emphasized that it is required to ventilate for thirty minutes after blasting downhole (such as blasting in the open air for 15 minutes) Personnel entered the site inspection. Otherwise, there will be a gunpowder poisoning accident.
