一、矿井粉尘的危害 煤炭工业发展史,是一部与自然灾害作斗争的历史,而煤尘瓦斯又是导致煤矿重大事故的原因之一。煤尘是伴随煤炭生产而产生,伴随通风、运输等环节而扩散,波及范围广泛,污染煤矿作业环境,是煤矿安全生产的主要隐患之一。 由于机械化、自动化水平日益提高,高效率的采掘设备的使用,煤矿开采强度加大,产尘量也随之增加,对于劳动卫生条件和生产的危害性表现得越来越突出。 国内外煤炭生产历史表用,煤尘爆炸往往给矿井带来毁灭性灾难,危害是严重的。据不完全统计,英国在1911-1941年的三十年间,曾发生146次煤尘爆炸事故。美国在1925—1945年的20年间,也发生过30次煤尘爆炸事故。1906年法国古利耶尔无瓦斯矿井,
First, the hazards of mine dust The history of the coal industry is a history of fighting natural disasters, coal dust and gas is one of the reasons leading to major accidents in coal mines. Coal dust is produced along with coal production. With the spread of ventilation and transportation, coal dust spreads in a wide range and pollutes the working environment of coal mines. Coal dust is one of the major hidden dangers in coal mine safety production. Due to the increasing mechanization and automation, the use of high-efficiency mining equipment, the strength of coal mining is increased, the amount of dust produced also increases, and the harm to labor hygiene conditions and production is becoming more and more prominent. History of coal production at home and abroad with the table, coal dust explosion often bring devastating disaster to the mine, the damage is serious. According to incomplete statistics, Britain had 146 coal dust explosions in the thirty years from 1911 to 1941. In the 20 years from 1925 to 1945, the United States also had 30 coal dust explosions. 1906 French Gully no gas mine,
