中国煤炭学会煤矿安全专业委员会于1981年11月5日至10日在重庆召开了煤矿粉尘学术交流会,参加会议的代表91人,交流论文43篇。在学术交流与讨论中,与会代表认识到我国煤矿粉尘的危害是严重的。近十年来发生的重大爆炸事故中,煤尘爆炸次数占近10%,而且大范围的瓦斯爆炸通常总是有煤尘参加。从劳动卫生的观点来看,煤矿的尘肺病也很严重。尘肺病有不可逆性,很难治愈,而且常常有合并症发生,造成死亡。煤 Coal Mine Safety Committee of China Coal Society held a coal mine dust academic exchange meeting in Chongqing from November 5 to November 5, 1981 with 91 delegates attending the conference and 43 papers exchanged. In academic exchanges and discussions, delegates recognized that the hazards of mine dust in China are serious. In the recent major explosion that occurred over the past decade, the number of coal dust explosions accounted for nearly 10%, and a large number of gas explosions are usually always attended by coal dust.
