On increasing the effectiveness of fine gold extraction during the exploitation of placer deposits
The main purpose of the research is to increase the efficiency of fine gold extraction from clayey auriferous sands at one of the deposits in Khabarovsk Territory. The author has concluded that the use of reactant treatment of the source material allows increasing the effectiveness of gold extraction 2,2 times.

A rational technology for deep placers mining
The author suggests mining the deep placers using a unified technical and managerial-technological approach, which should include joint operational exploration and sampling, setting up the areas with off-balance reserves and within these areas – producing blocks with amenable and off-spec content of gold and barren rock.

Evaluating the stability of the open-cast mine bench slopes and walls during the deposits development using a combined method
The calculation of stability of the open-cast mine side walls uses the adhesion of the solids in the massif. The transition from the solids adhesion in the sample to that in the massif can be made using the massif structural attenuation coefficient, the value of which depends on a number of mine engineering factors.

An innovative technique for underground operation geometrizing using self-travelling production machinery
The authors suggest allotting the industrial and technological ore grades which can be selectively extracted during the underground operation geometrizing using self-travelling production machinery. It will allow to purposefully program the mineral and raw material potential with due account for the certain industries' interest to the individual ore grades.

Modelling the spatial variables using the neural nets (one-dimensional case)
The author proposes a method for selecting a naturally determined component meeting a certain criterion of the neural network model in conditions of a limited data set. He provides a statistical analysis of the obtained results with construction of a regression model of the spatial variable's random component dispersion.

3D modeling of limestone massifs at Derbent occurrence
The authors have analyzed the structures of the physical and mechanical parameter models of a saw limestone massif. They have performed the geostatistical calculation of the amenable limestone reserves within the area adjacent to the working pit wall of Pervomaisk open cast. The discrepancy with the calculation using the geological blocks method is less than 5%.

Surveying supervision over the development of earth surface deformations during the exploration of hydrocarbon deposits
The authors describe the actual state of the surveying supervision over the allotments of the mined hydrocarbon deposits. They also consider the advisability of studying the earth surface displacement for the purpose of more precise rendering of the petrophysics using the surface surveying supervision data (solving of inverse problems). Besides, some problems of survey measurements accuracy are exposed.

The ways of resolving the environmental problems during stowing operations at the mining enterprises
The authors have invented and introduced at Maleyevo mine (Zyrianovsky ore-dressing complex, «Kaztsink» limited partnership) the scheme for reclaiming the rock produced during the drivage without drawing the rock to the surface and storing it in waste heaps.

Main roof collapse energy propagation and its interconnection with gas-dynamic processes in coal mines
The authors have developed a method for finding the values of the primary and the subsequent collapse steps, as well and the absolute gas emission value under the stated load upon the production face. They came to the conclusion that such processes as rock pressure formation, rock deformation and strata movement, gas emission, rock bursts, coal and gas rush must be considered as an integrated process.
