Abstract

for settlements located near mines and quarries, it is often necessary to zoning areas that are affected by mining operations. Most often, their influence is manifested in the form of subsidence of the earth's surface, sometimes sinkholes. It is particularly relevant for the "factory-type" towns of the Urals, where historically industrial settlements developed together and on the basis of mining and metallurgical industries, often having common borders. After decades, and sometimes centuries, the justified and safe use of these territories causes serious problems due to fragmentation and lack of information about their condition. A similar problem was encountered by the Berezovskiy town in the Middle Urals, most of whose territory was undermined. The closure and subsequent flooding of part of the mines of the previously city-forming gold mine led to the need to study its territory. To do this, a method was developed and zoning was performed in a step-by-step manner in the geoinformation system, and the consequences of flooding were established. In the process of implementation, all the engineering-geological, geodetic and other information provided by the mine was used. The results are unique due to the uniqueness and heterogeneity of the parameters of underground workings, sinkholes on the earth's surface caused by workings that are densely located on the studied territory.
