Monitoring technology and method of ecological environment rehabilitation and treatment in Jvhugeng mining area

The Jvhugeng mining area of muli Coalfield is located in the wetland ecological area at the source of Datong River,a tributary of the Yellow River,and is a key area for ecological environment protection in the Yellow River Basin.A series of ecological and environmental problems caused by coal mining,including landform destruction,land destruction,water system wetland destruction,unstable slopes and abnormal high temperature of residual coal,have caused disturbances and damages to the ecosystem of the mining area,resulting in a decline in the ecological service function of the mining area and the quality of the ecological environment.In order to comprehensively analyze the ecological environment problems in the mining area,clarify the direction of ecological environment restoration and governance,ensure the efficient development of the ecological environment restoration and governance projects in the mining area,and effectively improve the quality of the ecological environment in the mining area.Based on the analysis of the status quo of the ecological environment,the mine environment restoration and governance is divided into four stages,namely,the survey and design stage before the governance,the topography and landform improvement stage during the governance,the soil cover and greening stage,and the later management and protection stage after the governance is completed.Aiming at the monitoring targets at different stages,using satellite remote sensing,low-altitude UAV remote sensing and informatization technology,give full play to the technical characteristics of InSAR,thermal infrared and three-dimensional remote sensing,combined with conventional geological survey,geophysical prospecting,drilling and other means,According to local conditions,the application of satellite remote sensing technology in vegetation coverage,frozen soil inversion and deformation monitoring has been explored.UAV remote sensing technology has been used in basic topographic surveying,ecological environment problem investigation,visual evaluation of ecological governance effects,engineering supervision and methods.The application of quantity calculation and other aspects has a good consistency after comparison and analysis with actual survey results.The research and construction of the Jvhugeng mining area’s ecological environment restoration and management monitoring technology model has effectively supported the restoration and management of the Jvhugeng mining area’s ecological environment.Good use has been made in the deployment and engineering monitoring of mine environmental management in the alpine ecologically fragile area of the upper Yellow River effect.
