煤层气勘探开发和利用的环境影响分析

煤层气是煤层中自生自储的一种非常规天然气，其成分主要是甲烷。与煤和石油比较，煤层气是一种清洁能源，因此加快煤层气的开发和利用，能改善能源结构，缓和能源紧张状况，减少环境污染。根据煤层气的特点，详细分析了其对于大气环境、水环境以及土壤、植物的影响因素后指出：开发利用煤层气对大气环境的影响利大于弊，而对水体、土壤、农作物等则产生一系列不利影响。

Environmental impact analysis of coal bed gas exploration, development and utilization

Coal bed gas is an unconventional natural gas which was self produced and stored in the coal layer.Its main ingredient is methane.Compared with coal and petroleum the coal bed gas is a clean energy resources,so it can improve energy resource structure,relax the tension of energy resource,and decrease envirionment pollution to speed up its development and utilization.Based on the coal bed gas feature,analyzing in detail the influence of development coal bed gas on environment,it has been pointed out that there exist more positive than negative to surrounding atmosphere,though there is a series of unfavorable effects on surrounding water,soil and plants etc.
