离柳矿区位于山西省河东煤田中段,吕梁背斜西翼、晋陕峡谷黄河东岸,包括离石、柳林、中阳、临县和方山5县,是国家确定的实行保护性开采的三大炼焦煤基地之一。全矿区含煤面积4842.5km~2,预测储量500亿t;总勘探面积992km~2,探明储量125.07亿 t。其中被国家列为稀缺煤种的主焦煤61.73亿 t,占探明储量的49%。尤其是上部山西组煤层,煤质优良,洗后灰分在10%以下,硫分一般不超过0.6%,与澳大利亚、加拿大、苏联、波兰等国的出口煤相似,用其炼制的焦炭质量高于英国特级冶金焦。离柳矿区小窑开采历史悠久。目前,全矿区共有矿井195对,其中国营矿15对,乡镇办矿57对,村办矿120对,个体矿3对。共批准井田面积318.07km~2,地质储量22.65亿 t;现有生产矿井81对,1989年生产原煤
Liuligang District is located in the middle of Hedong Coalfield in Shanxi Province, west of Luliang anticline and east coast of Yellow River in Shanxi-Shaanxi Gorge, including Lishi, Liulin, Zhongyang, Linxian and Fangshan 5 counties. It is a state determined to implement protective mining One of the three coking coal bases. The coal area of the whole mining area is 4842.5km ~ 2 with a predicted reserve of 50 billion tons; the total exploration area is 992km ~ 2 with proven reserves of 12,507 million tons. Among them, 6.173 billion tons of main coking coal, classified as scarce coal by the state, accounted for 49% of proven reserves. In particular, the coal seams in the upper Shanxi Formation are of excellent coal quality. Ash content after washing is less than 10% and sulfur content is generally not more than 0.6%. Similar to the exported coal in Australia, Canada, the Soviet Union and Poland, In the United Kingdom premium metallurgical coke. Liu mining from the small kiln mining has a long history. At present, there are 195 pairs of mines in the entire mining area, of which 15 are state-owned mines, 57 are mines managed by villages and towns, 120 are mined by villages and 3 are individual mines. Approved a total area of 318.07km ~ 2, geological reserves of 2.655 billion t; 81 existing production mines, raw coal production in 1989
