摘要
【目的】为评估煤矿采空区建设场地的适宜性。【方法】本研究以济源市某光伏发电项目为例,基于评估区地质环境条件、地质灾害类型及特征,并结合野外调查成果、建设工程特征,采用定性、定量的方法,预测煤矿采空区光伏发电项目建设场地地质灾害的危险性并进行分级,对建设场地进行了综合评估。【结果】工程建设项目涉及的地质灾害类型主要为地面塌陷、基坑边坡失稳等。评估区煤柱边界内地质灾害危险性中等区基本适宜该工程建设,对工程建设可能引发和遭受的地质灾害应采取避让、抗变形结构技术、禁采、基坑边坡崩塌防治等有效措施;煤矿煤柱边界以外为地质灾害危险性小区,建设场地适宜该工程建设。【结论】针对评估结果提出防治对策,为项目防灾减灾及其他类似工程提供地质灾害性危险评估参考。
[Purposes]In order to assess the suitability of the construction site in the goaf area of a coal mine.[Methods]Taking a photovoltaic power project in Jiyuan as an example,based on the geological en⁃vironment conditions,types and characteristics of geological hazards in the assessment area,combined with the field survey results and the characteristics of construction engineering,the geological hazards of the construction site of the photovoltaic power project in the goaf of coal mine are predicted and classified by qualitative and quantitative methods,a comprehensive evaluation of the construction site was carried out.[Findings]The types of geological disasters involved in engineering construction projects are mainly ground subsidence and slope instability of foundation pit.The middle area of geological hazard within the boundary of coal pillar in the evaluation area is basically suitable for the construction of the project,effec⁃tive measures such as avoidance,anti-deformation structure technology,prohibition of mining,slope col⁃lapse prevention and control should be taken for the geological disasters that may be caused and suffered by engineering construction,the construction site is suitable for the project.[Conclusions]In the light of the evaluation results,the countermeasures are put forward to provide a reference for the evaluation of geological hazards in disaster prevention and reduction projects and other similar projects.
