The Article contains the results of researches of dynamics in changes of physical and mechanical properties of enclosing sedimentary rocks and hard coals of the Kuzbass and Vorkutsk deposits. The general condition of change in permeability factor on gas was obtained, depending on forms and types of moisture bonds in rocks and intensity of stress state. In the research tasks necessary for solving the problem of methane extraction, the methodological aspects are a matter of interest to study the processes of sorption-desorption in natural gassaturated coals. Study of the sorption characteristics of coal has shown that its sorption capacity depends on the stage of metamorphism within the whole studied range of saturation pressures.

Ways for providng safety in designing of intensive coal mining at the Kuznetsk basin
Problems are generalized for the purpose of providing safety in coal deposits mining at the Kuzbass. It was shown that the basis for providing safety should be a complex of safety measures in corporating a repeat geodynamic zooming of the overall Kuzbass, individual deposits and mine fields, multiphase degassing at all stages of mining , and also the gaseous, seismic, hydrogeomechanical and electromagnetic monitoring at productive mines. It was suggested to work out safety regulations for providing safety during intensive coal mining not for each individual holding, but for the whole Kuzbass.

- Authors:
- Ien Grei
- Yu. S. Shelukhina
This paper examines the issues of mining gassy coals. These cover a huge range of coal types, gas contents, permeabilities and diffusional behaviour. The key to understanding what approach to take to mining, is an understanding of the geology and the correct measurement of the important parameters. This must be followed by suitable interpretation and a flexible mining approach to dealing with the geology, geotechnical and reservoir conditions. The paper describes some of the techniques used in exploration to define these parameters.

New objective laws of methane exhalation during intensive mining of shallow coal seams
Natural observations and mathematical modeling of methane exhalation during increase of intensive mining in shallow coal seams have found that when excavation speed of coal area movement increases, process of methane desorption and its filter into atmosphere of working face is delayed. Discovered objective laws are subject to create scientific base to determine loading factor of highly productive working face, allowed as per gas ratio.

Safety problems of mining operations in high-stress hard rock massif
- Authors:
- A. A. Kozyrev
- V. I. Panin
- Yu. V. Fedotova
Intensive development of large-scale deposits in high-stressed rock masses results in sharp activation of mining-induced processes in the earth depths and the surface thus initiates increasing of seismic activity in the mining area and hazard of rockbursts and mining-induced earthquakes. As reliable spatial-temporal prediction of dynamic events in the mines is problematic in the current state of methodology and geomechanical experiment technique, therefore, it is required to assess risks of these events which scale determines corresponding preventive measures.

Experience in application of geophysical methods for stress-strain state of rock mass control with the goal of altering design solutions in liquidation the flooding of the emergency section of mine № 1-5 of the Barentsburg coal deposit
The paper presents the results of observations of stress-strain state at the Barentsburg coal deposit by means of the «Angel» equipment with the the purpose of detecting sections prone to manifestation of dynamic forms of rock pressure. The investigated sections of mine field were flooded for a long time, therefore after drainage the original cycles of geophysical measurements have been conducted at all development workings and at production face by applying recording techniques for natural electromagnetic emission, recording of background component of natural electromagnetic field of the Earth, seismoacoustic emission (shock) and seismoacoustic emission (natural), pulsed by points (profiles) along the workings. Parallel with geophysical observations measurements with KDM-1 device were made and visual ob- servations were carried out.

Provision of geodynamic safety in mining the Barentsburg coal deposit
The minable seam «Verkhny» within the Barentsburg coal deposit is geodynamically hazardous, its geodynamic phenomena manifest itself in the form of proper rock bursts, shocks in the marginal zones and dynamic faults of ground. Due to rockburst-hazardous situation the application of the areal relief of rock mass with transition to technological variants of mining with leaving the extended rib pillars at the boundary with the mined-out space, with their cutting by drivage of additional working is applied. Consideration is given to the recommended variants of pillar leaving with the data of their assignment and applicability to geological-and-mining conditions of mine field sections. Description is given to the calculation of pillar sizes and parameters used for their calculations. Some examples are given of pillar leaving at different sections of mine field with geometrical parameters as well as the information is given on the seam extraction with prospecting routes (paths) with leaving the support rib and barrier pillars. The leaving of safety support and barrier pillars with substantiation of their sizes is recommended as the method for providing the safe condition of mining the «Verkhny» coal seam
