Technology, informational support and analysis of open mining of steep dipping deposit with in-pit rock placement
Presented are the technologies and the results of the investigation of open mining of a dip throw ore deposit with intraquarry location of rock. Revealed are tendencies of change in the intraquarry spoil bank volume, additional extraction of overburden and ore, volume of rock in the quarry at the beginning of intraquarry spoil bank formation, losses f ore and power intensity of transportation and location of rock in the spoil bank depending on its volume and position in the quarry. Given are optimized technological solutions.

Prospects of placer gold extraction rate enhancement using blocked mini-drags
In the article, mini-drags major advantages are revealed – their mobility and ability to work in shallow water quarries. A technologic scheme for techno gene placer development has been proposed, which enables it to move drags aphelia tailings to on-shore installations for their secondary processing.

Rope-bolting of mine workings in the presence of unstable formations in the roof
The authors provide the results of laboratory and underground tests of anchor and rope bolting of mine workings roofs in unstable argillaceous and saliferous materials. The bolts are designed by Soligorsk Resource Saving Institute with Pilot Production. They can be used in different geological and mining conditions of coal and saline deposits.

On selection of the method for the analysis of geomechanical condition of the flank-side mass affected by the underground mining
The author proposes the calculation methods and formulas for exploring the geomechanical condition of the flank-side mass of a mine affected by the underground mining. Among these methods the most advisable is the theoretical one. It has been found that from the research reliability point of view the most acceptable is the linearly elastic model of the massif.

Control of underworked areas subsidence using the radar interferometry methods
Based on the research of the quick land subsidence caused by the grave accident at the First Berenzikovsky mine, the authors consider the opportunities for using the satellite radar interferometry techniques for monitoring of the deformations of the underworked areas. They demonstrate the effectiveness of the radar interferometry control of the land subsidence and the limitations of the technique due to the presence of snow cover during winter and the forest cover.

On digital camera calibration
It has been found that the distortion of digital images depends on the focal length of the camera's lens. The distortion is especially great when the focal length is the smallest (7.1 mm). The most efficient technique for correcting the images geometry involves using the calibration module of RxSpotlight PRO Version 6.0.458 by Microsoft Corporation. It allows increasing the object positioning accuracy manyfold.

Extraction of fold and silver from the flotation wastes of barite complex ore of Madneul deposit
The wastes remaining after flotation of barite-complex ore at Madneul mining and processing enterprise contain 2,54 tonnes of gold and 81 tonnes of silver. For extraction of these metals a thiocarbamide method was used, which had been previously tested with goldbearing quartzites, barite-goldbearing concentrates and Madneuli copper-zinc concentrate.
