在现场地质调查的基础上,结合物理模拟试验,对贵州省大方县云龙山变形体特征及其孕育演化过程进行了深入研究。云龙山所在区域石灰岩分布广泛,地形切割剧烈,谷深坡陡,坡脚六个煤硐的开采导致整个上覆坡体变形开裂并发生浅表层崩滑破坏,属于典型的地下采空区诱发上覆坡体失稳案例,其变形破坏过程可以概括为:煤层开采—采空区坍陷—坡体沉陷开裂—坡表失稳。
On the basis of on-site geological survey, combined with physical simulation test, the deformation characteristics of the Yunlongshan in Dafang County, Guizhou Province and its inoculation and evolution process are studied in depth. The limestone in the Yunlongshan area is widely distributed, the terrain is severely cut and the steep valleys are steep. The mining of six coal bores at the foot of the slope leads to the deformation and cracking of the overlying slope and the occurrence of superficial layer collapse and collapse. It belongs to the typical underground gob- Case of slope failure, the deformation and failure process can be summarized as: coal mining - goaf collapse - slope subsidence cracking - slope instability.
