华亭县是全国13个重点产煤县之一,2005年初在县境内砚北煤矿采区附近的砚峡乡翠峰山发生山体裂缝、滑坡灾害,因灾害严重,危险性大,曾引起省市县高度关注。通过调查分析,本区大规模采煤是引发砚峡滑坡变形失稳的主要诱发因素,可以说大规模采空及采矿工程活动对特殊的井田地质结构的累进性破坏导致该地段斜坡滑移。本文针对滑坡特征提出了防灾对策。
Huating County is one of the 13 key coal-producing counties in China. In early 2005, cracks and landslides occurred in Mt. Cuifeng, Yanxia Township, near the Yanbei coal mine in the county. Due to serious disasters and serious danger, highly anticipated. Through the investigation and analysis, the large-scale coal mining in this area is the main inducing factor for the deformation instability of Yanxia landslide. It can be said that the progressive destruction of the special geological structure of the minefield caused by large-scale goaf and mining engineering activities leads to the slope slips. In this paper, the landslide characteristics proposed disaster prevention measures.
