冷水江市浪石滩滑坡及其防治措施探讨

Landslide at Langshitan,Lenshuijiang city and the Measures for its Control

浪石滩大型滑坡的形成,除具有自然边界条件、地质结构面和斜坡地貌形态外,还有地下溶洞的带状发育,也是重要原因之一。而井下采煤造成的顶板岩层位移变形,则是诱发滑坡的主要原因。由于地下采煤与滑坡密切的成生联系,预测发展下去,滑坡造成的灾情惨重。因此,做好治理前的地质勘查与采煤时的地表变形防治极为重要。

Apart from the natural margin condition, geological strocture plane and slope landform. the devel-opment of karat caves in belts is one of the important causes of the formation of the large scale land slide at Lang-shitan. But the shift and deformation of roof rock layers caused by coal mining in pits is the major reason to induce the disaster. According to thc close genetic rclationship between coal mining and landslide, it may be predicted that ahe disaster will be scvere in the future if the situation develops as it is. The extreame importance is to make a geological investigation and prevent the deformation of landsurface in mining area before governing and control ling it.
