吉林省永吉县岩溶地区开展地质灾害危险性评估的重要意义——以芹菜沟水泥用灰岩矿为例

Geological hazard assessment of qincaigou cement limestone minein Yongji County

本文通过对芹菜沟水泥用灰岩矿的地质环境条件的综合研究,从地层地貌、地层岩性及地质构造、岩土类型及工程地质条件、水文地质条件等三个方面的叙述,认定芹菜沟水泥用灰岩矿工程地质条件属于简单类型。进而对评估区进行了地质灾害危险性现状评估、地质灾害危险性预测评估,综合其评估情况,提出了评估结论和防治措施,总结了岩溶地区开展地质灾害危险性评估工作的重要意义。

In this paper,through the comprehensive study of the geological environment conditions of the limestone mine used for cement in Qincaigou,from the stratigraphic landform,stratigraphic lithology and geological structure,rock and soil types and engineering geological conditions,hydrogeological conditions three aspects of the description,identified that the engineering geological conditions of limestone mine used for cement in Qincaigou belong to a simple type.Furthermore,the present situation and prediction of geological disaster risk in the assessment area are evaluated.Based on the evaluation results,evaluation conclusions and prevention measures were proposed,and the significance of conducting geological hazard risk assessment in karst areas was summarized.
