随着矿井生产过程机械化程度的提高,采掘工作面推进速度快,产量高,煤尘生成量和瓦斯涌出量也大幅度上升,这不仅有害工人健康,而且具有煤尘爆炸危险的矿井对煤矿安全生产的威胁也加重了。所以在生产过程中,都要把安全第一的方针放在首位。现在不少矿井采用了防尘措施,有的矿井还采用了防爆与隔爆措施,防治灾害的经验也比过去多了,但是防止煤尘爆炸事故的发生依然是我们煤炭工业部门的重点之一。
With the improvement of the mechanization of the mine production process, the working face of mining excavation has the advantages of fast propulsion, high output, large increase of coal dust generation and gas emission, which not only detrimental to the health of workers, but also has the danger of coal dust explosion. The threat of safety is also exacerbated. Therefore, in the production process, we must give top priority to safety first. At present, many mines use dust-proof measures. Some mines also adopt explosion-proof and explosion-proof measures, and experience in disaster prevention and control is also more than before. However, preventing the occurrence of coal dust explosion accidents remains one of the focuses of our coal industry department .
