Estimating the parameters of the applicability of a cassette sweeping gear for deep-water sampling of ferromanganese nodule deposits
Estimating the parameters of the applicability of a cassette sweeping gear for deep-water sampling of ferromanganese nodule deposits

The article presents main data on sea-floor solid mineral (SM) deposits and proves the importance of their development. A cassette sweeping gear is proposed for bulk sampling of nodule-bearing deposits with the substantiation of its characteristics. The methodology is described of the calculation of the required lifting force for the delivery of boomerang canisters to the surface. The dependences have been calculated for the estimation of a sweeping gear design parameters and its operation patterns.

The role of the tin resources of the far eastern region in the revival of the tin industry in Russia
The role of the tin resources of the far eastern region in the revival of the tin industry in Russia

The article analyzes the situation in the tin industry of Russia his raw potential, where the main mineral resources sub-sector is the Arctic area North-East of the country. Defined the state of the world tin-mining industry, of tin reserves, production, consumption and world market conjunctures. Evaluation of mineral-raw material base of tin in the Republic of Sakha (Yakutia) and prospects for its development. The problems and causes of crisis to the tin industry in Russia and regions, including republics is showed. Proposed ways out of the crisis resource base sub-sector allows reducing or even excluding the import of tincontaining raw materials, as well as the main directions and measures for the advancement and development of the tin mining industry.

Providing safety and efficiency of blasting operations at coal opencast mines of Mongolia
Providing safety and efficiency of blasting operations at coal opencast mines of Mongolia

The article presents summarized information on geography and climate of Mongolia, with the emphasis on the peculiar characteristics having an effect on the efficiency and safety in mining operations employing the blasting method of rock breaking. The authors describe an opportunity of finding some reasonable solutions for the use of natural phenomena resulting in the alteration of physical and mechanical characteristics of ammonium nitrate and perfection of the quality of ammonium nitrate-based multicomponent explosives. The technologies of explosives fabrication are described, which provide the efficiency of blasting processes in various conditions, including loosening of coals liable to spontaneous combustion.

Organization monitoring of deformations of earth’s surface on the Uzelginsky and the Talganskoe ore deposits

The method of instrumental geodynamic monitoring displacement of earth surface on Uzelginsky and Talganskoe ore deposits and the results of determination of deformation in the vertical and horizontal planes are presented. The spatial coordinates of a framework and geodynamic network stations were re-observed using a method of satellite geodesy. The parameters of the trend of modern geodynamic movements caused by the formation of the basin subsidence were determined. The vectors of movements of the marks of the observation station were identified as the result of estimate of geodynamic activity, the graphs of the stressstrain deformation and shear deformation, the discrete mosaic pattern of deformation of the rock mass were identified. The assumptions about future course of the earth’s surface deformation of the examined area are presented.

 On the development of modern Russian thickeners
On the development of modern Russian thickeners

Mineral preparation and processing technology widely incorporates thickening and clarification processes. These processes are closely associated both with the problem of external and internal water cycle, and with the efficiency of production technology. Today, in Russia and CIS thousands of operating thickeners in various application areas need modernizing. It is necessary to commission over 20 new thickeners annually. In the current geopolitical situation the demand of mineral mining and processing industries for high-quality import-independent machinery and equipment has notably grown. To perform the task of modern Russian thickener supply, in an ideal scenario it is necessary to initiate the work on the elaboration of a comprehensive development program for this area. The article presents the analysis of the problem state-of-the art, and proposes measures aimed at the development of thickening and water cycle equipment by national designers and manufacturers.

Scientific and technical aspects of the updating of management arrangements in surface mining in case of robotized open-pit machinery application

The article describes the approach in the development of the Intelligent Mine System and updating of management arrangements in surface mining in case of robotized open-pit machinery application. For the application of a robotized haulage system it is important to arrange a sequence of organizational measures of mining and transport machinery fleet management. This company actually becomes a mined material haulage subcontractor with the responsibility for t-km and compliance with the declared machinery utilization factor, and availability factor of the whole Intelligent Mine system. In this context it is important to emphasize the importance of deeper involvement of mining companies, research establishments, surface mining machinery manufacturers and engineering companies, which are the developers of robotized haulage systems, in the discussion and approval of the philosophy of operation and responsibility for the availability of such systems to avoid unaddressed management issues when the technology implementation is in its active phase.

Resource Nationalism

Resources nationalism is on the ride around the globe. During the recent global resources boom many governments have adopted this policies to maximize the political and economic benefits from their mining and energy sectors. The contemporary resources nationalism takes a range of distinct forms, which are connected to differences in political institutions, structural objectives and goals as well as state policies in different countries.
