爆破是矿山生产的主要工序之一,其主要分为地面和井下两大类。由于爆破材料的不同,在爆炸后所产生的有毒气体亦不同。研究爆炸后一些有毒气体的消长,对于保护工人健康很有意义。为此,我们进行了对铵油炸药井下(洞穴)爆破后二小时内氮氧化物、一氧化碳等有害气体的消长试验,现将结果报告如下,以供参考。 Blasting is one of the main processes of mine production, which is mainly divided into two major categories of surface and underground. Due to the different blasting materials, the poisonous gas generated after the explosion is also different. Studying the growth and decline of some toxic gases after the explosion is of great significance for the protection of workers’ health. To this end, we carried out the ammonium nitrate explosives downhole (cave) within two hours after the blasting of nitrogen oxides, carbon monoxide and other harmful gases, the test results are reported below, for reference.
