Jiaoping mining area is located in the northeast of Jurassic coalfield in Huanglong, Shaanxi Province, adjacent to Huangling mining area in the north and starting from the outcrop line of Miaowan-Jiaoping coal seam in the southeast.
West to Ziwuling at the junction of Shaanxi and Gansu, southwest to Miaowan, Liujiadianzi and Xunyao mining areas temporarily.
In the mining area, discerning, Shuangmiao and Shanmiao are the watershed.
The northeast belongs to the Luohe River system, including Heqian River, Nanchuan River, Yuhuachuan River and other rivers, all of which are southwest-northeast, with small flow. The southwest belongs to Jinghe River system and Shichuan River system, separated by Laoyeling-Changsheling.
The strata exposed in the mining area are mainly sand and mudstone of Yanchang Formation of Upper Triassic, sand, gravel and mudstone of Fuxian Formation of Lower Jurassic, sand and conglomerate of Yan 'an Formation and Zhiluo Formation of Middle Triassic, sand, conglomerate and mudstone of Yijun Formation, Luohe Formation and Huachihe Formation of Lower Cretaceous, and scattered tertiary and quaternary loess widely distributed on the platform.
The average thickness of Yan 'an Formation in coal-bearing strata is 40 ~ 80 m. ..
There are 8 layers of coal, only 4-2 # coal seam is the only minable coal seam in this area, with a thickness of 0 ~ 34 m, generally 8 ~12 m. ..
Geographically, the mining area is located in the southeast edge of Ordos Basin, with simple structure, few faults and gentle strata.
The geological structure is dominated by wide and gentle folds with little fluctuation, and the structural lines are mainly east-west and northeast, followed by northeast, with a small amount of north-south direction.
Fold width is generally 2 ~ 5 km, axial length 12 ~ 45 km, amplitude 40 ~ 200 m, and dip angle 2 ~ 10.
The amplitude and dip angle of folds decrease with the formation from old to new.
Geologically speaking, the mining area is located in the southeast section of Huanglong coalfield in the south of Mesozoic large depression in the interior of Shaanxi-Gansu-Ningxia basin, belonging to Jurassic continental coalfield.
The strata include Yanchang Group of Upper Triassic, Fuxian Group of Lower Jurassic, Yan 'an Group of Middle and Lower Jurassic, Zhiluo Group of Middle Jurassic, Zhidan Group of Lower Baiping and Quaternary.
Among them, Yan 'an Formation and Zhiluo Formation developed alluvial facies. According to records, the mining history in this area is very long. During the Ming and Qing Dynasties, a large number of small coal mines were mined along the outcrop of coal seams. The postal code is 727000.
Area code: 6 10203.
Telephone area code: 09 19.

Jiaoping Coal Mine belongs to Tongchuan City, Shaanxi Province. Located in the transition zone between northern Shaanxi Plateau and Guanzhong Basin in the hinterland of Sanqin. It has two geomorphic units, which have the comprehensive characteristics of natural conditions in the north and south. It faces the rolling Ziwuling in the north and the vast and rich Weihe Plain in the south. It is 0/00km away from Xi 'an/Kloc-0, the ancient capital of the Nine Dynasties, 80km away from Huangdi Mausoleum, the ancestor of humanity, and 240km away from Yan 'an, the revolutionary holy land.
The name of Jiaoping Coal Mine originated from Jiaoping Township, yijun county City, Shaanxi Province (200 1 12.23, the original Jiaoping Township merged with Mafang Town and was renamed Taian Town). The former Jiaoping Township is in the southeast of Jiaoping Coal Mine. Locals call Jiaoping Township Old Jiaoping to distinguish it from Jiaoping Coal Mine.
Jiaoping Coal Mine belongs to Tongchuan Mining Bureau, Shaanxi Province, and is located in Jiaoping Township (formerly yijun county), 37 kilometers away from Tongchuan City. Mei (Jiaping) 17 (Lizhen) Railway leads to He Qian Station in the east of the mining area. This road leads to the Ministry of Mines.
Before 1958, there were only some private small coal mines in the mine field.
1958- 196 1 During the Great Leap Forward, Jiaoping Coal Mine was gradually formed.
He Qian open pit mine, northeast tower adit, Yonghong inclined shaft and avant-garde adit have been produced successively.
Located in Tacun, northeast of Jiaoping, it is an independent mine field with a strike length of 2.8km, an inclined width of1.4km and an area of 3.9km2..
Tunnel development, single horizontal panel mining up and down the mountain, boundary ventilation, main mining 4-2 coal seam, designed annual production capacity of 450,000 tons.
Tongchuan Infrastructure Company/kloc-0 started construction in June, 1967, and/kloc-0 started production in May, 1969, with a total investment of188.09 million yuan. The average ton of coal in the mine is put into 42 yuan, the roadway excavation is 9 129 meters, and the building is 20,938 square meters.
After put into production, the output hovered between18-320,000 tons for seven consecutive years, and 1977 rose to 353,700 tons, and 1978 produced 515,600 tons of raw coal.
After 1979, the annual output will remain at the design capacity level.
1969- 1990 * * produces 6,795,200 tons of raw coal.
In July, 1990, 1 was approved to stop production and scrap.
A raw coal screening, transfer, loading and storage system (called coal preparation building locally) with an annual design capacity of 6.5438+500,000 tons (considering the needs of Yuhua contact well) was built in Northeast Tower area, which provided convenience for coal loading and transportation.
Located in Yanggou, Jiaoping, Tongchuan Mining Bureau raised funds to build it.
/kloc-0 started construction in March, 1970, and was completed and put into operation that year.
The designed annual production capacity is 6.5438+500,000 tons.
This mine field belongs to a corner of Jiaoping coalfield, with a strike length of 2. 1 km, an inclined width of 1.4 km and an area of 2.9 square kilometers.
A pair of inclined shafts were developed, the main inclined shaft is 960 meters long and the auxiliary inclined shaft is 940 meters long.
Due to the mismatch of production links, it was adjusted from August 1980 to 198 1 again.
1970- 1990 and Qianwei adit produced a total of 6,938,700 tons of coal (the two wells were not counted separately).
