摘要
在勘探、生产过程中,煤层气会对周边地质环境造成不良影响,需要开展地质环境保护与土地复垦工作。煤层气由于地理位置的特殊性,其矿山地质环境保护与土地复垦方案也有所不同。以四川筠连煤层气田为例,煤层气开采对地质环境的影响主要体现在地质灾害、含水层破坏、地形地貌景观破坏、水土环境污染及土地资源压占等方面。针对这5种地质环境影响,需要采取相应的监测工作,并根据土地利用现状和预测开展恢复治理工程等措施。文章论述和探讨了合理的煤层气田地质环境保护与土地复垦方案,以求为同类工作的开展提供借鉴和参考。
Impact to surrounding geological environment to some extend happens in exploration and mining process of coalbed gas,therefore it is necessary to conduct work of geological environment protection and land reclamation.Due to particularity of coalbed gas geographical position,its mine geological environment protection and land reclamation plan are also different from others. Taking Junlian coalbed gas field in Sichuan as an example,the impacts of coalbed gas mining on the geological environment is mainly reflected in five aspects: geological disaster,aquifer destruction,topographical landscape destruction,soil and water environmental pollution and land resource occupation and compression. In view of these five geological environmental impacts,it is necessary to take corresponding monitoring work,and to carry out restoration and control projects according to the existing situation and planning of land use. Through review and discussion,reasonable scheme of geological environment protection and restoration for coalbed gas field is presented in this paper,which can provide some reference for similar work.
