SPECIFICS OF DIAGNOSTICS OF TECHNICAL CONDITION OF TRANSPORT AND TECHNOLOGICAL SYSTEM “MINING GAS PIPELINE – MINE WORKING”

The purpose of the paper is to analyze a deformation mechanism mine degassing pipelines forecast their spatial changes in terms intensification underground mining coal-gas seams.
 Methodology. deals with expert assessment available approaches diagnostics technical condition pipelines, which are constructed within in-seam workings floor rocks prone heaving. results scheduled surveying measurements development have helped identify potentially hazardous zones rock mass and indices location section mounted those workings. To determine operating modes pipeline under such conditions, computer model interaction elements transport-technological system “mine gas – working” has been developed
 Findings. Diagnostics conditions transmission lines examination dismantled components understand that deflections, mainly resulting water accumulation zones, intensive corrosion internal pipe walls, mechanical depositions coal dust take place right flange connection areas. Formation argued by health as well air inflow. Availability corrosion, accumulations, inflow decreases substantially capacity line inclusive qualitative characteristics captured methane-air mixture efficiency MDS on whole.
 Originality. New difficult geological gas-bearing seams substantiated it offered consider indicators functioning interacting space time "mine - mining".
 Practical implications. operational parameters systems notes equipment performance least underpressure losses created vacuum pipes requires should minimum hydraulic resistance network. Pipeline aeration from accumulations be prevented means hermetic sealing its connections straightness corresponding pitches. Consequently, basic requirements for involve design profile, tightness operative control facility health.
