Procedure of assessing the rib pillars stability when using pillar-and-breast systems
The author proposes a procedure of assessing the rib pillars when mining the reserves of potassium-salt deposits using pillar-and-breast systems. The proposed technique allows estimating the pillars' stability with account of the mining operations phase. It allows planning and filling the mined-out space.

Determining the optimal amount of reserves ready for extraction during open-pit mining of complex-structured deposits
When setting the norms of extractable reserves, the mutual influence of the following basic factors must be taken into account: excavator haul cost, the losses caused by maintaining throughout the year on all the horizons the reserves required for complete removal of the mineral product above the reserve band, the losses due to the increase of the current strip ratio, the loses caused by decline in the mineral product output due to the necessity to maintain the required amount of exposed reserves.

Problems and development prospects jf the mining science
The author describes the present-day state of the Russian mineral and raw-materials base and predicts it further deterioration. He stresses that under the present conditions the efficient use of resources in integrated subsoil resources development is of utmost importance. The author also emphasizes the necessity of exploring the production induced deposits, namely waste banks and tailings dumps at concentrating mills. He sets forth the priority techniques of georesources development and utilization – the framework of a number of critical federal level geotechnologies.

Classification of the sources of solid minerals quality variation during their exploration
The classification of solid minerals' quality variation sources during exploration of mineral deposits allows unifying the loss records in all the subsectors of the mining industry, comparing and assessing by the losses level the work of individual crews, mines, open pits, integrated plants, companies, firms, mining enterprises or holdings. Coupled with the classification of the sources of the mineral materials' quality change it will provide a clearer understanding of the present-day state, dynamics and operational trends of the country's mineral and industrial complex.

On rational use of sylvinite beds at Upper-Kama potassium salts deposit
The authors have developed basic engineering solutions for extraction of a complex-structured sylvinite bed and an off-spec thickness bed at Upper-Kama potassium salts deposit. They propose engineering solutions for the second working during extraction of the off-spec thickness bed. The use of the proposed technique will allow increasing the sylvinite extraction from subsoil 1.4 times while ensuring the useful component content in the ore at a level of 30%.

The use of metering pump equipment in the processes of gold heap leaching from auriferous ore dumps
The depletion of gold field reserves brings us to the necessity to search for the ways of developing gold-bearing dumps and rebellious ores. Both domestic and foreign experience proves that the use of advanced technologies and equipment in the course of development of such ores allows.

Development of coal industry in China and the prospects of cooperation between Russia and China
The author characterizes the present-day state of the coal industry in China and its growth prospects. He cites the data concerning the Sino-Russian cooperation in coal trading and the creation of the joint coal-mining enterprises in Siberia and the Russian Far East planned in the years immediately ahead. The author gives detailed description of the negative effect produced by China's coal producers on the natural environment. He emphasizes that the most important problem of coal mining in China is safety of the coal mines' operation.

Geomechanical justification of the heading-and-stall method parameters for the stopping operations in transition zone of Xin-Kuen minefield (Vietnam)
For the purpose of stoping, under the mine a heading-and-stall system is designed and the mined-out space is supported by pillars. The author proposes a method of calculation of the permissible dimensions of rock exposure in the stalls, floor pillars and rib pillars.
