顿巴斯各矿井由于开采深度大,煤体瓦斯含量大,有煤(岩)与瓦斯突出危险,作业的危险性很大。煤矿的平均开采深度已超过750 m,其中有12个矿井,开采深度在1 000～1 400 m之间。随着开采深度加大,围岩温度升高,煤体的瓦斯含量和突出危险也增大。此外,有90%的煤层属于瓦斯煤层,60%属于煤尘爆炸危险煤层,45%属于煤岩和瓦斯突出危险煤层,25%属于自然发火
Due to the large depth of mining and the gas content of coal seams, all the coal mines in Donbass have the danger of coal (rock) and gas outburst and the operation is very dangerous. The average coal mining depth has exceeded 750 m, of which 12 mines, mining depth of 1000 ~ 1400 m. As mining depth increases, the surrounding rock temperature increases, the gas content of coal and the prominent danger also increases. In addition, 90% of the coal seams belong to the gas seam, 60% belong to the coal seam explosion hazard seam, 45% belong to the coal and gas outburst dangerous seam, 25% are spontaneous
