摘要
矿产资源开采导致矿区地表频繁发生地质灾害,严重制约了矿山智能化的建设进程,监测并预警地质灾害的发生对于矿区正常生产及防灾部署具有重大意义。当前矿区地质灾害主要依靠传统地面监测手段及In SAR等方法,存在费时费力、周期长及In SAR无法监测大梯度形变等不足,无人机低空遥感作为一种新兴手段,以其独特的优势已经被广泛应用于矿山地质灾害监测中。结合现阶段典型成果及课题组近年来的探索实践,简述了矿山地质灾害的类型,分析了无人机低空遥感矿山地质灾害监测的应用现状,总结了无人机低空遥感在开采沉陷监测、煤火识别及地质灾害监测等方面应用的基本流程,提炼了现阶段无人机遥感实时高精度沉陷盆地构建、水平位移监测及多源时空数据融合等技术发展亟需攻克的技术难点,并从无人机高精度数据采集、多类型载荷协同、5G实时传输及智能灾害监测等方面展望了未来发展方向。未来矿山地质灾害要向“多网融合+实时监测+智能作业+任务协同+全面感知+自主决策”的智能监测预警体系方向发展,需要多学科、多部门学者开展协同攻关,实现“产学研用”联动发展。
The mining of mineral resources leads to frequent geological disasters on the surface of mining area,which seriously restricts the construction process of mine intellectualization. Monitoring and early warning of geological disasters is of great significance to the normal production and disaster prevention deployment of mining area. At present,the geological disasters in the mining area mainly rely on traditional ground monitoring methods and In SAR methods,but there are shortcomings such as time-consuming and laborious,long cycle,and In SAR cannot monitor large gradient deformation. As a new method,UAV low-altitude remote sensing has been widely used in the monitoring of mine geological disasters with its unique advantages. Based on the typical achievements at the present stage and the exploration and practice of the research group in recent years,this paper briefly describes the types of mine geological disasters,analyzes the application status of UAV low-altitude remote sensing in mine geological disaster monitoring,summarizes the basic application process of UAV low-altitude remote sensing in mining subsidence monitoring,coal fire and geological disaster monitoring,and refines the technical difficulties that need to be overcome in the current stage of UAV remote sensing real-time high-precision subsidence basin construction,horizontal displacement monitoring and multi-source spatio-temporal data fusion. The future development direction is prospected from the aspects of UAV high-precision data acquisition,multi-class load coordination,5G real-time transmission and intelligent disaster monitoring. In the future,the monitoring and early warning of mine geological disasters should be developed in the direction of intelligent monitoring and early warning system of " multi-network integration + real-time monitoring + intelligent operation +task coordination + comprehensive perception + independent decision-making",which requires multi-disciplinary and multisector scholars to collaboratively tackle key problems,and realize the joint development mode of " industry-university-researchapplication".
