在我国许多煤矿,由于煤层赋存较深或开采深度较大等原因,使得井下的巷道及采煤工作面距地表的高差较大,导致地温对矿井生产及煤层自燃的作用显著增大。本文在分析地温对煤层自燃影响的基础上,着重阐述巷道煤层自燃火灾的特点及其防治。 In many coal mines in our country, the height difference of the roadway and the coal mining face from the ground surface is large due to the deep occurrence of the coal seam or the large exploitation depth, which leads to the significant increase of the ground temperature on the mine production and spontaneous combustion. Based on the analysis of the influence of ground temperature on spontaneous combustion of coal seam, this paper focuses on the characteristics and prevention and cure of spontaneous combustion of coal seam in roadway.
