Innovative Engineering Complex Development Outlook

Abstract
The peculiarity of mining production implies a comprehensive range of applied equipment manufactured by different companies and firms which makes its maintenance processes difficult, increases field costs and decreases cost-effectiveness. For a particular coal company it is of a big interest that a single manufacturer supply a required machine set while assuming the responsibilities of a general contractor for guaranteed resources and a final result of the equipment operation. Having brought together the engineering companies within a management company made it possible to establish a unified coal engineering industry center engaging a number of global mining machinery companies which is capable of changing the existing situation and providing coal industry companies with a world class mining equipment.

A Concept of Designing a Ventilation System Ensuring Lower Methane & Powdered
Coal Explosion Risks in Cul-de-sac of Longwall

Abstract
The article offers an updated a cul-de-sac longwall ventilation concept whose difference lies in the fact that a full fan pressure should be calculated for a ventilation system made up of a fan, control units, ventilation airways, mine working face, working area and the rest of the mine working up to the pit mouth. This approach makes it possible to improve the reliability of ventilation parameter calculation and tunneling machine operation safety. The concept uses as guidance the air flow movement mechanism obtained by the authors during their laboratory studies, fundamental physical laws and chemical processes which occur in methane-dust-air mixtures in the working area. Also taken into account is the effect of methanes increased molecular concentration in mine workings on lower bottom concentration limits of methane flammability and explosibility.

Keywords
Ventilation system, Lower methane explosion risk, Powdered coal, Cul-de-sacs.

Technologies for Establishing High Drainage Capacity Zones
in a Methane-coal Bed: How to Increase Coal Methane Downhole Flows

Abstract
A large-scale industrial production of coal field methane accounting for billions of cubic meters per year was launched in many countries around the world (USA, Canada, India, China and so forth) and the main method for coal methane recovery is a coal bed frac job through vertical wells. Similar works were started in Kuzbass, Russia, in early 2000s which allowed JSC Gazprom to proceed to regulatory and legal rationale of a new methane coal subindustry. Within the framework of this article the author once again tries to propose engineering solutions (which were used previously for underground gasification of coal) to establishing artificial high drainage capacity collectors in a methane-coal bed. This would allow the coal methane production to be increased not through a number of well drilled but through a multiple increase in its flow from every well.

Keywords
Coal methane, High drainage capacity zones, Filtration surface, Coal bed kindling, Coal bed frac job, Pneumatic-hydraulic impact on the hydraulic fracture crack, Flame working of drilled channels in a methane-coal bed.

Economic Crisis as a Deep Coal Processing Incentive

Abstract
The global economy has stepped into a transition period of changing basic technological structures characterized by a considerable instability. The leading scientists recognize that a relative stabilization would take many decades. An early understanding of this situation gives a competitive edge to the manager teams who would be the first to make a turn to mastering new technological scenarios for their company development. According to the author for the coal industry its a turn from tendency to produce additional millions of tons to making high added value products which can only be ensured by deep coal processing.

Extending Steel Jib Headframe Service Life at Kuzbass Mines

Abstract
The article proposes a method of upgrading an existing steel jib headframe for repair-and-renewal operations or for a transition to a multiple-rope lift by reinforcing a jib using a central tubular stand which ensures a calculated headframe lay-out modification. This reduces part of a load from the lift operation falling on the machine which would make it possible to avoid reinforcing its elements and consequently a shutdown of the shaft during the upgrade. A technical solution using a machine unloading will ensure that man-hours as well as costs and times for a prospective mine construction can be reduced.

Keywords
Steel bench type headframe, Headframe element reinforcement, Lift upgrade.
