ADVANCEMENT OF PROCESS OF RE-EXTRACTION OF COAL RESERVES IN PECHORA FIELD

Abstract

Methods of selecting rational flow charts relating to re-extraction of pillars for the Vorgashor and similar deposit conditions have been created. The methods include the breakdown of reserves in terms of production volume and geometric parameters re-extraction areas and a modular diagram system by the technological and geomechanical substantiation of the efficient and safe production. A block diagram used for solving the problem of improving the process of coal pillar production has been developed. New problems associated with the evaluation of the geomechanical state of the rock mass and substantiation of safe parameters used at the re-extraction process, have been solved. The problems of evaluating a dynamic phenomenon hazard in the re-extraction areas have been solved. The results of the investigations have been used for the "Vorgashorskaya" mine conditionsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
