我国煤矿目前的生产建设,除部份回采工作面采用机采、水采外,普遍采用炮掘炮采。全国煤矿年用炸药21万吨左右,雷管近5亿发。矿用爆破材料的生产、运输、贮存和井下使用都有爆炸性危险。特別是井下爆破,如果违反规程、错误操作,就可能造成直接爆炸事故或引起瓦斯、煤尘爆炸以及其它事故。为保证煤矿安全生产,减少这些事故的发生,《煤矿安全规程》第七章“火药和井下放炮”专门作了四十七条规定。在这一章中应着重理解下面三个问题:
The current production and construction of coal mines in China, except for some mining face using machine mining, water mining, the general use of artillery mining mining. The annual coal mine explosives around 210,000 tons, detonators nearly 500 million hair. Mine blasting material production, transportation, storage and underground use are explosive dangerous. In particular, blasting downhole, if the violation of the rules, the wrong operation, it may cause a direct explosion or cause gas, coal dust explosion and other accidents. In order to ensure the safe production of coal mines and reduce the occurrence of these accidents, Article 47 of the Chapter 7 “Gunpowder and Mine Blasting” of “Coal Mine Safety Regulations” was specifically made. In this chapter, we should focus on understanding the following three issues:
