由于褐煤和木煤煤层的含水量为5～25%,同时,井下巷道内空气中的含煤尘量也较低,所以对煤尘潜在的爆炸危险性问题重视不够。近10～15年来,随着机械化采煤工艺的不断发展,井下巷道内的含尘量明显增加。巷道内煤尘积聚浓度增加,加上井下空气含有瓦斯,曾多次引起爆炸,因此,需进一步分析煤尘爆炸的可能性。对波斯尼亚—黑塞哥维那地区开采的两种牌号的煤的煤尘爆炸特性进行了以下研 Due to the water content of lignite and wood coal seam is 5 ~ 25%, at the same time, the amount of coal dust in the air of the underground roadway is also low, therefore, the potential explosion risk of coal dust is not paid enough attention. In the recent 10 to 15 years, with the continuous development of mechanized coal mining, the amount of dust in underground tunnels has obviously increased. Increasing the concentration of coal dust in the roadway, coupled with underground gas containing gas, has repeatedly caused an explosion, therefore, the need for further analysis of the possibility of coal dust explosion. The coal dust explosion characteristics of two grades of coal mined in the Bosnia-Herzegovina area were studied as follows
