山西交城县采空塌陷地质灾害发育特征及防治对策

Characteristics of Geological Hazards Caused by Mining and its Preventive Measures in Jiaocheng County,Shanxi Province

交城县是山西省吕梁市的一个产煤大县,同时也是一个地质灾害严重频发县。灾害类型主要有地裂缝和地面塌陷,其发生与地质背景及人类工程活动密切相关,其中采煤活动是引起该县地质灾害的主要原因。地质灾害的形成发育严重影响了当地村民的日常生活和地区经济发展。在调查研究交城中东部地区采空塌陷地质灾害时空分布的基础上,本文结合区域地质、水文地质、工程地质等地质环境条件及人类经济工程活动,分析了地质灾害的发育特征,探讨了地质灾害形成机制,确定了该地区地裂缝的非构造属性,并提出了相应的治理对策。

Jiaocheng is one of the large coal-producing county of Lvliang City in Shanxi Province, where geological hazards occurred seriously and frequently. The hazards types, including geofraeture and collapse, are closely related to the background conditions of geography and human engineering activities. Coal mining activities is the main reason for geological hazards. The formation and development of geological hazards have severe impact on daily life of local people and the regional economic development. On the basis of investing spatial and temporal distribution of the geological hazards caused by mining collapse in the middle -eastem part of Jiaocheng, the characteristics of geological hazards are analyzed according to the regional geology, hydrogeology, engineexing geology, geological environmental conditions and human economic activities. The mechanism of geological hazards formation is discussed and non-structural attributes of the geofracture is determined, and the corresponding countermeasures are put forwarded.
