| 摘 要： | 煤层气是一种廉价、洁净、高效的新型能源,其开发利用可以弥补常规天然气和燃油的不足,750m^3煤层气可顶替1t标准煤。煤层气开发对环境的影响主要是减少了煤矿甲烷气体的排放,降低温室效应。其负面影响是在钻探、压裂、回注水和提纯过程中会造成煤层和煤层气中杂质气体和有毒有害物质富集,对大气和地下水造成污染。

| Abstract: | C BM is a kind of cheap,clean and high efficiency new type energy,its exploitation and utilization can make up insufficiency of conventional natural gas and fuel oil,750m3 of CBM can substitute 1t of coal equivalent.The influence of CBM exploitation on environment is mainly reduced coalmine methane release,and eased greenhouse effect.Its negative impact is enrichment of impurity gas and poisonous,harmful substances in coal seam and CBM during drilling,fracturing,reinjection of water and purification processes will pollute atmosphere and groundwater. |
