摘　　要：以平煤十二矿的焦煤、煤矸石、矿井水为研究对象,在添加接种物的情况下,研究产气量和甲烷含量,结果表明:发酵液在荧光显微镜照射下拍的照片,证实了产生的气体中确实存在甲烷气,试验过程中产生的甲烷的碳同位素值与煤矸石的碳同位素值接近,说明煤矸石中的碳参与了微生物作用,接种物的加入量与产气量和甲烷含量密切相关。在进一步研究获取、利用生物气时,可以考虑利用采残煤和不可采煤层中的煤炭资源。This text measures the quantities of gas and the contents of methane based on the coking coal,gangue,mine water of pingmei twelve mine and in the case of adding inoculum.The results show that： the photo shoot fluorescence microscope,have confirmed the existence of gas in the methane gas,the CH4＇s carbon isotope value in the experiment is similar to the gangue＇s,that is to say gangue is involved in the microbial role,the quantity of inoculum is directly related to the quantities of gas and the contents of methane.In the further research for obtaining and using the biogas,we must consider using the mining of coal and non coal mining residual layer of coal resources.
