Geological Environment Assessment Of Facing Stone Mine In Aojiang River Basin Based On Remote Sensing

The author undertakes the project of "UAV aerial image interpretation in the centralized mining area of Aojiang drainage basin".The UAV aerial image interpretation technology used in this project has the characteristics of quickness and accuracy in obtaining the evaluation index of mine geological environment.Therefore,this article relies on "Aojiang River Basin decorative stone centralized mining UAV aerial image interpretation" project.Through the aerial image interpretation,the basic data of geological environment evaluation index of Aojiang drainage basin decorative stone mining was obtained.Through the literature review method,the geological characteristics of the facing stone mine summarizes.On this basis,it puts forward that it is suitable to evaluate the geology environment of veneered stone mine by adopting the grid method and analytic hierarchy process.Specifically get the following conclusions:(1)In the land occupied by stone development,the area occupied by solid waste is relatively large,and a large amount of solid waste accumulation not only occupies large amounts of land,but also has potential safety hazards.Among them,295.66 ha of solid waste from Gutian County accounted for 52.63% of the total land area of Gutian Mine;145.73 ha of solid waste from Lianjiang County accounted for 49.61% of the total land area of Lianjiang Mine;412.14 ha of solid waste from Luoyuan County was occupied.Source mine covers an area of 49.25%.The 853.53 ha of solid waste in the facing stone mines in the Aojiang River Basin accounted for 50.43% of the total area of the entire basin.(2)The surface stone mines are mostly open-pit mining,and the main types of damage are stope digging and waste slag pressure.The main geological environmental problems caused include resource damage,“three wastes” pollution,and hidden dangers of land disasters.(3)The grid method and AHP used in this study are more suitable for evaluating the geological environment of facing stone mines.The evaluation results of the mine geological environment in the study area showed that the non-affected area accounted for 99.5945% of the total area;the general area accounted for 0.3233% of the total area;the more serious area accounted for 0.0819% of the total area;the serious area accounted for 0.0003% of the total area.
