华亭县砚峡滑坡成因及防灾对策研究

摘要

Huating County is one of 13 major counties which produce coal in China.It is at the beginning of 2005 when massif rift and landslide happened in Cuifengshan neighboring to mining area of Yanbei coal mine in Yanyia town.From the result of investigation,it%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。
