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。
In order to ensure the safety of the construction of photovoltaic power plants in the mining subsidence land, it is necessary to carry out the assessment of the stability of the foundation of the goaf and to carry out the goaf treatment if necessary. Taking the construction of subsoil of Datong, Shanxi as an example, this paper introduces the general situation of photovoltaic power station construction in subsidence land. Based on the characteristics of surface subsidence and related theories and applications of subsidence in the mining area of Datong, according to the requirements of different stages of photovoltaic power station construction project, The stability assessment of the foundation at different stages is carried out and some technical measures such as the exploration of unknown goaf and the treatment of dangerous goaf are put forward in a targeted way.
