矿井深度对甲烷气体解吸量影响规律研究

Research on Relationship Between Depth of Coal Seam and Quantity of Gas Produced

根据新汶矿业集团孙村煤矿13#煤层的地质资料及实验室分析,运用数值计算软件拟合出了孙村煤矿地温与深度的关系式,并在此基础上根据实验室实验得出了该煤层甲烷气体的解吸量与矿井深度的关系式。

Based on the geological and the experimental data,the relationship curve between the depth of coal seam and the amount of gas produced has been fit out.According to this and the laboratory experiments,the relational expression between the quantity of CH4 and the period of spontaneous combustion has been obtained.
