Landslides, falls, and rock displacement in Uzbekistan mineral deposits

The paper explores formation of landslides, falls, and rock displacement on the basis of the Tegenek, Jigiristan quarry, Olmaliq, Angren, Kurgashinkan deposits. The formation conditions determined landslides on slopes during open-pit mining development, landslides inside quarries, landslides over underground mine workings, falls on the quarry sides and mine workings. The authors established formation conditions for each process type associated with the deposit development. A steady growth in the mining scales, intensity, and depth, as well as a long-time mining object operation lead to formation of landslides, falls, and rock displacement. During the solid mineral deposit development, an increase in the extracted rock volume, underground mining depth, and variety of mining workings enhances the role of technogenic factors in forming geotechnical processes. The increased numbers of drilling and blasting operations, as well as changes in deposit development technology result not only in intensifying geotechnical processes complicating the mineral resource production, but also triggering their new forms. The outcomes therefore raise the geotechnical intensity level of the environment and require additional factors to consider upon designing and operating mining objects.
