无人机低空遥感在采煤塌陷区地裂缝特征提取中的应用

Application of Low Altitude Remote Sensing by UAV in the Extraction of Ground Fracture Features in Coal Mining Collapse Area

地裂缝是地质灾害中地面变形灾害之一,它是直接或间接地恶化环境、降低环境质量、危害人类和生物圈发展的地质事件。传统的人力检测地裂缝测量方法在进行测量时,测量精准度不够高,山区地势复杂等原因,需花费较长时间对地裂缝进行测量,以至于提高了地裂缝提取的难度。基于目前存在的问题,本文应用无人机遥感技术,选取测区开展地裂缝提取和特征分析,查明了塌陷区地裂缝分布数量与特征规律,对服务鄂尔多斯采煤塌陷区生态治理和灾害防治具有一定研究意义。

Ground fracture is one of the ground deformation hazards among geological hazards, and it is a geological event that directly or indirectly deteriorates the environment, reduces the quality of the environment, and endangers the development of human and biosphere. The traditional human detection ground fracture measurement method is not accurate enough when making measurements, and it takes a long time to measure ground fractures due to the complicated terrain in mountainous areas, so much so that it raises the difficulty of ground fracture extraction. Based on the existing problems, this paper applies UAV remote sensing technology to select the measurement area for ground crack extraction and feature analysis, and identifies the number of ground cracks distribution and feature pattern in the collapse area, which has some research significance to serve the ecological management and disaster prevention and control of coal mining collapse area in Ordos.
