– LEGAL ISSUES OF SUBSOIL USE
Omarov G. Z., Kryuchek S. I., Dudikov M. V. State provision of economic interest in the relations of subsoil use. Part 3 – р. 4
The article investigates the economic methods of public interest in the relations of subsoil use. The characteristic of absolute and relative legal relations from the position of legal regulation of the subsoil use process is given. The methods of providing the economic component of the public interest, which are divided into the following groups: fiscal method (method of direct seizure of property); method of gratuitous support; method of economic stimulation (contractual method); management method. When considering the economic methods of ensuring public interest, proposals for improving the legislation are presented.
Keywords: economics; public interest; the Law on Subsoil; subsoil; subsoil; legal; fiscal method; method of grant support; a method of economic incentives; legal method; method of management; taxes; fees; cadastral valuation.

Gusev V. N., Kutepov Yu. I., Borger E. B., Kutepov Yu. Yu. The forecast of formation of the cracks having the nature of a collapse in a layer of breeds of a surface of big thickness – р. 16
Results of observations of shift and deformations of the land surface and the system analysis of these natural measurements of parameters (width of disclosure and depth of penetration) of the cracks created owing to these processes are given in layer of breed of the big thickness relating to the land surface. On the basis of the received functional dependence of these parameters of cracks from deformations of a surface the technique of the forecast of development of width of disclosure and depth of penetration of cracks is presented. The geomechanical scheme of processes of formation of cracks with transition to a stage of collapse of their walls is provided. As a result of a crack take the form of a collapse of breeds of the land surface.
Keywords: curvature; horizontal deformations; width of disclosure and depth of penetration of cracks.

Kulikova E. Yu. Monitoring as a basis for georisk reduction at the development of underground space – р. 57
Cornerstone for the substantiation, rock mechanical and geotechnical support for the development of underground space are monitoring data. Up-to-date monitoring is unthinkable without an appropriate instrument base. This instrument base and engineering support were created in NUST “MISiS” by scientists from the Department “Construction of Underground Structures and Mining Enterprises” and specialists of the “Telemac” Company. The article reveals the main aspects of geomechanical and technological risks formation during the development of underground space of the cities and proposes measures to minimize them on the basis of monitoring and engineering measures.
