- Abstract:
- The article describes the procedure for reviewing and approving regulatory legal acts containing mandatory requirements. Licensing requirements for the production of surveying works are considered for compliance with the principles of legislation on mandatory requirements. A brief overview of standardization initiatives in the field of surveying support for the development of oil and gas fields is given. The characteristic features of the preliminary national standard for surveying the development of UVS deposits are described. The authors conclude that the regulation of surveying works is in a state of systemic crisis and suggest solutions.

- Abstract:
- The article presents the results of modeling of dredging waste in the dredge section in dynamics, depending on the depth of the dredge section and the difference in the granulometric composition of the sands, which became the basis for constructing a mathematical model. It has been established that the most common method of dumping is after-part of dredge. It is determined that the dilution of the tails of the dredging waste of sand in the bottom of the dredge has one of the greatest effects on the quality indicators of production. It is shown that the 3D model of the dredging waste allows you to simultaneously take into account many input parameters, while each previous filled dredging waste raises the subsequent dredging waste in height, which leads to a sharp increase in the volume of sands entering the dredge face. It was revealed that with an increase in the depth of dredging, the volume of diluting sands sharply increases. The results of the research can be useful in the development of technological solutions that can reduce the impact of dilution of the sands of dredging waste at the stages of field design and development.

- Abstract:
- The article presents the results of quantitative studies focused on the analysis of quantitative data of imported mining equipment operated during open mining of mineral deposits in the Magadan region. It has been established that currently more than 11% of the reserves of proven placer gold, 15% of ore gold and about 50% of silver from the total volumes of proven reserves of these metals in the Russian Federation are concentrated in the Magadan region. It is determined that imported mining equipment is used in all areas of production. The results of the research may be useful to managers of gold mining enterprises. This work is devoted to the primary section on the search for preventive ways out of the artificial shortage of mining equipment provoked by the current geopolitical situation.

- Abstract:
- The article shows the specificity of cryogenic relief formation along the route of the Power of Siberia-2 gas pipeline in the southern part of Gorny Altai. The main advantages and disadvantages of the new version of the route, its natural conditions are considered with an emphasis on cryogenic relief formation. The aspect of the demand for Russian natural gas in the industry of the PRC, Mongolian People's Republic and in our country is highlighted.

- Abstract:
- Oil is the main source of energy consumption today, serving over 30% of the world's energy demand. Its transportation is an important problem in supply, both nationally and internationally. The aim of the work is to study methods for transporting oil with anomalous properties, such as low fluidity and high paraffin content. The effectiveness of the additive method is shown on the example of oil from the Republic of Kazakhstan. It is revealed that the combination of «hot» pumping with the addition of additives gives the best result. The results of the research can be useful in solving oil transportation problems for fields with high viscosity.

- Abstract:
- Carbonate reservoirs offshore the Gulf of Guinea contain a significant proportion of the remaining conventional oil reserves, most of which are classified as naturally fractured. These reservoirs are well known for their low recovery rates compared to similar clastic non-fractured reservoirs. The stratigraphic, tectonic and gas-bearing features of the region are considered. A method for studying cores for porosity is proposed, which makes it possible to numerically estimate the volume of the deposit.

- Abstract:
- The article presents the results of studies of the accuracy of geodetic and surveying constructions in difficult conditions of narrow mine workings. The main method of work in such conditions is the resection produced by an total station. It is shown that compliance with strict requirements for the geometry of such serifs is difficult. The necessity of theoretical and practical studies of this issue is substantiated. Experimental confirmation of previously performed theoretical studies is given. It is confirmed that with the high accuracy of modern instruments and the joint processing of linear and angular measurements, the geometry of the inverse linear-angular serif does not significantly affect the accuracy. The results of the experiments are shown and their brief analysis is given. The results of the research can be useful to specialists of geodesy and surveying, working at construction and mining facilities, both in open and underground mine workings.

- Abstract:
- The article discusses the main trends in the development of the «green» economy in the world and the concept of the transition of the state to this economy. The results of the use of technogenic raw materials (enrichment waste, overburden and host rocks) for resource conservation and the development of solution compositions for strengthening and hardening fractured rocks and construction structures are presented. The waste of the Akshatau Mining and Processing Plant was investigated and the possibility of their use during mining (underground structures) in fractured rocks was confirmed. An effective solution based on enrichment waste has been developed to strengthen and harden disturbed rocks in underground workings by increasing their strength characteristics. The research results can be used to expand the raw material base of construction materials, as well as to increase the level of industrial safety at mines and minimize environmental risks caused by the development of the subsoil. The significance of the results obtained for the construction industry lies in the expansion and reproduction of the raw material base of the construction materials industry through the use of MMC waste (enrichment tailings) and the development of resource-saving technologies.
