Results of Monitoring Changes in the Karst Failure in the Tula Region Based on Remote Sensing from an UAV

摘要

Many large cities of Russia,including Moscow,Perm,Kazan,Tula,are located in zones of strong influence of geological hazards,especially karst formation,causing great damage to human life.According to satellite imagery in the Tula region,numerous heaps of developed rock(tailings)are visible,as well as karst subsidence and dips of the earth's surface,which in some places form linear chains.Such objects were identified and began to be explored in the middle of the XIX century.To identify the dynamics of the change in failure,processing was performed to obtain 5 results of subtracting the primary 3D model from the next 5.The maximum change in the contour of the dip along the surface of the earth in a westerly direction by 5 m was established.Efficiency of field research is especially important when studying such dangerous geological objects as pingos in the Arctic and mud volcanoes.The work was carried out according to the state assignment on the topic Rational use of natural resources and efficient development of oil and gas resources of the Arctic and subarctic zones of the Earth(No.AAAA-A19-119021590079-6)
