【正文】 53893706 II Abstract This is a new design for workable coal seams,they are 4 36a、 2 27 Total thicknes of coal seam mine is long and mine area is coal seam industry trademark is 1/3 coking mine field recoverable resources . This mine pit design uses take the double vertical shalt development the division as two levels,eight pick working face can achieve lane transporation uses 5tons Bottomdump mine cars to transport,uses long wall mining on the strike to mine coal wining technology is full mechanized coal wining technology, use the caving method for all working faces. Key Phrase:the mine pit design vertical shaft development moves to wards the log wall to pick III 目 錄 摘要 ..............................................................................................................................
