Abstract: Geomechanical processes during coal layers long spreading pillars excavation are analyzed. It's shown, than the result is the forming of enclosing rock mass technological structuring, which parameters depends on rock mass energy and pit-face length. The parametric model of processes with structures' external surface waviness along pit-face and excavation pillar is described. The adequacy of the proposed model to real gas-geomechanical processes in coal gas-containing massif provides the essential growth of management technologies efficiency both on the project and mining stages.
