Thickness of coal seam is , , 15m from top to bottom. Slope angle of coal seam is 176。采煤方法為走向長壁采煤法，采煤工藝為綜合機械化放頂煤開采，采空 區(qū)處理方法為全部垮落法。 煤層的工業(yè)牌號為 1/3 焦煤。設計井田工業(yè)儲量 ，可采儲量 ，服務年限 。 主井采用一對 12t 箕斗提升，副井采用一對三噸雙層單車罐籠不平衡提升。 , industry card of which is 1/3 coking coal. Industry quantity of the mining filed is Mt, and the workable reserves is Mt, service life is . The mine design uses the double vertical shaft development. Shaft position is selected in the west of the storage center. The mine is divided into 2 levels, dopting concentrated main lane decoration。 Breaking Mining III 目 錄 摘 要 .........................................................................................................................
