第二次改扩建工程 葛店煤矿是原设计为年产21万t的小型矿井,1988年完成年生产能力30万t的改扩建工程。近几年原煤产量逐年递增,预计1993年可产原煤42万t以上。超过矿井生产能力的40％。煤炭供不应求,企业连年盈利,经济效益在全省地方煤矿中居领先地位。由于该矿具有开采条件好、煤质优良、地理位置好、经济效益好等优势。最近国家能源投资公司,中国地方煤矿总公司批准该矿井第二次改扩建工程项目。矿井改扩建扩大区位于葛店和新庄之间的双庙井田,井田南北走向长6km,东西倾斜宽1.5km,面积9km~2,地质储量6733万t,可采储量3002万t。矿井改扩建主要环节是在扩大区内打一立主井,用于提煤、回风、排水并兼作安全出口,副井采用 The second renovation and expansion project Ge Dian mine is originally designed for an annual output of 210,000 t of small mines in 1988 to complete the annual production capacity of 300,000 t of expansion project. In recent years, the output of raw coal has been increasing year by year. It is estimated that more than 420,000 tons of raw coal can be produced in 1993. More than 40% of the mine’s production capacity. In short supply of coal, the company profits year after year, economic efficiency in the province’s top coal in the leading position. As the mine has good mining conditions, good quality coal, good geographical location, good economic returns and other advantages. Recently, the State Energy Investment Company and China National Coal Mining Corporation approved the second reconstruction and expansion project of the mine. Reconstruction and expansion of mine The area of ​​Shuangmiao Mine, located between Gedian and Xinzhuang, is 6km long and 1.5km wide from east to west with an area of ​​9km ~ 2 with a geological reserve of 67.33 million tons and recoverable reserves of 30.02 million tons. Mine renovation and expansion of the main link is to play in the expansion area to play a main shaft, for coal, return air, drainage and doubles as a safe exit, vice wells used
