黄土湿陷与地面沉降对油气矿山地质环境的影响

The Impacts for Oil Mine Geological Environmental Assessment from Loess Collapse and Surface Subsidence

近年来,因矿区地面标高变化对采矿活动造成的负面影响越来越明显。通过分别调查西北地区黄土湿陷与东南沿海地面沉降的油气矿山地质环境问题,针对此类地面标高降低的问题对油气田矿山开发的影响进行评估。基于比较分析,详细论述了两类问题的起因、演化、影响等方面。针对上述问题的不同影响,提出了相应的治理恢复及监测等工程措施,有利于同类油气矿山的地质环境的保护与恢复治理。

In recent years, the change of ground elevation has negative impacts on mining. Based on the investigations of geological environmental problems about ground elevation reduction, which include loess collapse in Northwest and surface subsidence in coastal region, the assessment has been done for impacts caused by them. Through comparative analysis, it describe in details about their causations, evolutions and impacts. For the significant impacts of problems, it proposes measures of restoration and monitoring which benefit for oil exploitation.
