words: western Henan the coalfield
English: west East or west, Henan coalfield
interpretation of the text : Chinese ancient Mesozoic coal. Located in western Henan Province, roughly south of Zhongtiaoshan, the Beijing-Guangzhou railway line west of Zhengzhou to Luohe, barberry Mountains to the south, the triangular plane. 250 km long from east to west, eastern wide l20 km from north to south, west, change the narrow area of 30000 square kilometers, of which coal-bearing area of 9800 square kilometers. The coalfield including Shaanxi Mian, Yima, Yi Luo, Xin, Dengfeng, Yan Long, Ying Gong, a new secret linru, Yu County, Pingdingshan mine. 39 billion tons of coal resources, reserves l60 million tons, annual output of about 50 million tons. Carboniferous-Permian offshore briquette in 680 m thick, including the Upper Carboniferous Benxi Formation, Taiyuan Formation, Permian Shanxi Xiashihezi Shangshihezi group. Upper Carboniferous thickness of 20 to 40 m World Pipe network informed, shallow water, littoral sand and shale, limestone, with local coal layer three layers, the thickness of about l m. Shanxi Formation thickness 80 m, composed by Lu phase transition sandstone and mudstone, with mineable coal layer three, the bottom of the main mining region of the average thickness of 4 to 7 meters, the rest of the second floor of each thickness l ~ 2 meters. Lower Shihezi Formation 85 m thick and consists of continental sandstones and mudstones, with local coal layer l ~ 2 layer, the thickness of l meters. Upper Permian Shihezi Formation of 380 m thick, coal-bearing 5 to 20 floors, of which coal layer 2 to 5 layers, thickness 1 to 2 meters. Western Henan Coal Coal class is complete, and in general was something to the zonal distribution. Northern Yan Lung Ying Gong mine anthracite. South Xinan Yi Luo, Dengfeng Yu County, Xinmi mining area in turn with lean coal, lean coal, coke, again the south linru, Pingdingshan mining area for fat coal, gas coal belt, which was the regional magmatic thermal metamorphism superimposed made. Shihezi Formation coal rank below the Taiyuan Formation coal. Permian coal sulfur content less than 1%; ash: about 20% of the Shanxi Formation coal, Shihezi Formation coal from 30% to 35%. Western Henan coal field, fold-off area, the anticline at the Lu Archean click Paleozoic syncline core of the Upper Permian and Triassic. Coal Measures is located in the syncline two wings. l0 respectively mines located in the corresponding syncline, the strata trending east-west and the south was the north west, dip 10 ° to 40 °, the development of high-angle faults in the syncline, in some areas magma intrusion coal measures phenomenon. A small number of high-gas coal mine Pingdingshan mining area in the eastern part of the ground warm cellar. Jurassic origin of Jurassic coal is located in the western Yima City, east to west is 22 km long, 2 to 6 km wide from north to south, covering an area of 100 square kilometers. 1.2 billion tons of coal resources, reserves of 800 million tons, 4.8 million tons of annual output. The coal measures are 70 m thick sedimentary basin in the small mountain. Coal-bearing three-layer total thickness of 20 m. Long flame coal, ash 15% to 20% sulfur% ~ 2%. The discovery of coal and coal briquettes in the blast furnace site in the Western Han Dynasty in Zhengzhou ancient Ying World Pipe network informed. Currently Pingdingshan and Yima Mining Bureau, 2001 output 29.22 million tons of coal, local coal mine production of about 20 million tons.
