煤尘是煤矿最大的自然灾害之一。其带来的生命及财产的损失也远较其他事故为大。从一八六六年英国某矿发生大型煤尘爆炸事故起到目前一百多年间,全世界死亡人数在300名以上的重大煤尘事故发生多起。同时煤尘又是尘肺病之源,严重地威胁着矿工的身体健康及煤炭生产。因此,世界各主要产煤国家对煤尘的测定、抑制及防止煤尘爆炸等方面都作了许多工作,并取得了一定成绩。 Coal dust is one of the largest natural disasters in coal mines. Its life and property losses are also far greater than other accidents. From the huge coal dust explosion in a mine in Britain in 1866 to the present one hundred more years, there have been more coal dust accidents with more than 300 deaths worldwide. At the same time, coal dust is another source of pneumoconiosis, which seriously threatens the health of miners and coal production. Therefore, many major coal-producing countries in the world have done a lot of work on the determination of coal dust, suppression and prevention of coal dust explosion and have achieved some success.
