摘　　要：在煤矿开采过程中沉降监测对采空区所形成的沉陷盆地范围的圈定应用方面效果显著。但传统监测手段存在多种弊端,例如野外数据采集缓慢、采集信息量单一、数据精度较差等原因,对后期分析解释造成约束,使得成果结论存在一定的误差。激光雷达技术在沉降监测方面的应用发展迅速,数据采集中有效地降低了运作成本,数据精度高,信息量充分等特点,应用机载激光雷达技术手段研究煤矿矿区连续开采与地表移动变形规律,为同类矿山提供可借鉴优化开采模式,为矿区地质灾害防治提供预防对策,保障人民群众生命财产安全,促进矿区经济和社会可持续发展作出巨大贡献。In the process of coal mining,the effect of subsidence monitoring on the delineation and application of subsidence basin formed by goaf is remarkable.However,the traditional monitoring methods have many disadvantages,such as slow field data collection,single amount of information collection,poor data accuracy and other reasons,which restrict the later analysis and interpretation,and make the results and conclusions have some errors.The application of lidar technology in subsidence monitoring has developed rapidly.In data acquisition,the operation cost is effectively reduced,the data accuracy is high,and the amount of information is sufficient.The application of airborne lidar technology to study the continuous mining and surface movement and deformation law of coal mining area can provide reference for similar mines,optimize the mining mode,provide preventive countermeasures for geological disaster prevention and control,and ensure the safety of mining area It has made great contributions to the safety of people’s lives and property,and to the sustainable development of mining economy and society.
