METHOD FOR SEPARATE EXTRACTION OF THIN AND VERY THIN BEDS OF COAL AND ROCK

摘要

Method for separate extraction of thin and very thin beds of coal and rock includes breakage, transportation of coal and rock at working out face with mechanized complexes. In process of working out one simultaneously performs breakage of coal deposit to complete power and cutting ceiling (or floor) rocks. Transportation is performed through formation of load flow of coal and rock with loading coal to lower branch and rock to upper branch of scraper conveyor (or vice versa), respectively, with transportation of those flows in opposite directions by face to separate section drifts. Use of that technical solution provides preservation of quality and grade of coal, decrease of losses, promotes intensification of process of development of beds, etc.
