大同采煤沉陷区建设光伏电站地基稳定性评估及治理技术

Foundation Stability Evaluation and Goaf Treatment of Photovoltaic Plant in Coal Mining Subsidence Area of Datong City

摘要: 为确保采煤沉陷土地建设光伏电站的安全，必须进行采空区地基稳定性评估，必要时要开展采空区治理。以山西省大同市沉陷土地建设光伏电站为例，介绍了沉陷土地建设光伏电站的工程概况，基于大同矿区地表沉陷特点以及矿山开采沉陷相关理论和应用，根据光伏电站建设项目不同阶段要求，分别开展了不同阶段的地基稳定性评估，并有针对性地提出采取不明采空区勘查和危险采空区治理等技术措施。

Abstract: To ensure the safety of the construction of photovoltaic plant in coal mining subsidence area, it is very necessary to carry out the evaluation of foundation stability and goaf treatment. Taking the photovoltaic project in Datong city of Shanxi province as an example, project profile for the construction of photovoltaic plant in subsidence area was introduced. Based on the theory and practice of coal mining subsidence and coal mines in Datong city, according to the demand for different stages of photovoltaic project, the responding foundation stability evaluation were finally carried out. Some technical measures for goaf treatment were proposed for the construction of photovoltaic plant.
