陕西韩城矿区地表沉降变形研究

Study on surface subsidence and deformation in mineral region in Hancheng City,Shaanxi Province

陕西韩城市地质灾害类型比较单一,主要是由于对煤炭资源的不合理开采而引起的地裂缝、地面沉降,他们是影响当地经济发展和城乡建设的一个主要因素。对韩城市受灾区的地裂缝特征从天然和人为因素两方面进行了研究,在了解地下预留煤柱分布图后,对地裂缝的形成机理做了理论推导,认识到随着对煤炭资源掠夺式开采的加剧,地裂缝在空间上的分布与煤炭开采的方位有关,地裂缝的发展和开采速度等的关系也很密切。研究结果对韩城矿区的地下采矿有一定的借鉴意义。

The type of geological hazard is simplex in Hancheng City, Shaanxi Province, i. e. unreasonable exploitation of coal resources has resulted in subsidence and ground fissures hazards, which have hindered the development of economy and construction of local areas. On the basis of studying on ground fissures from natural background and man-made action and understanding the distribution of prearranging pillars, this article analyzes formation mechanics of ground fissures and realizes that with extensive exploitation of mine resources, the spatial distribution of the ground fissures is connected with the mining location and the development of ground fissures is related to the mining speed. The results of the article give a reference to ining in Hancheng City and other place.
