Xiaoyi coal reserves, by the end of 202 1 and 1, there were 670 coal mines in Shanxi province. All production coal mines must strictly abide by the relevant state laws, regulations, rules, regulations, standards and technical specifications, consciously accept supervision and supervision, and be filial to coal reserves.
Xiaoyi coal reserves 1 Xiaoyi is known as the "Three Treasures", with rich mineral resources, many varieties, concentrated distribution, good geological conditions and convenient mining. Xiaoyi's mineral resources, especially coal and aluminum, are the first batch of 50 coal-producing areas in China and 35 key coal-producing areas in Shanxi Province, and also the main development base of aluminum industry in China.
Xiaoyi coal resource is an important part of Huoxi coalfield, with a coal reserve of 783.5 square kilometers, accounting for 82.8% of the total area. The proven geological reserves are 765.438 billion tons, and the prospective reserves are 9 billion tons. The coal types of Xiaoyi coal are mainly coking coal, both fat coal and lean coal, among which: coking coal reserves are 2.564 billion tons (including 407 million tons in Liuwan Coal Mine; Shuiyu Coal Mine 3180,000 tons; Levin coal mine 65438+27 million tons; Yixing mine field 305 million tons; Baibiguan mine field is 346 million tons, accounting for 36.1%of the total reserves; Fat coal reserves/kloc-0.039 million tons, accounting for14.6% of the total reserves; The lean coal reserves are13.76 million tons, accounting for 19.4% of the total reserves. In addition, the coking coal reserves in Liu Li mining area adjacent to xiaoyi city are 7.038 billion tons. Xiaoyi city has abundant coal reserves, shallow burial, stable coal seams, complete varieties, good coal quality and easy mining.
The city's coal storage is divided into six areas: Levin, Shuiyu, Liuwan, Baibiguan, Jiaozili and Xingyue. Most of the resources have been taken away by provincial and municipal enterprises and contributed to the country, so people call it "a city rich in resources and a city poor in mining". Among them, the three major mines of Fenxi Mining Group and their planned mine fields cover an area of 435.96 square kilometers, accounting for 55.6% of the city's coal storage area; The geological reserves are 5.382 billion tons, accounting for 76.2% of the city's proven reserves. Lvliang Duizhen Coal Mine covers an area of 12.4 square kilometers, accounting for1.6% of the city's coal storage area; The geological reserves are 654.38+75 million tons, accounting for 2.5% of the city's proven reserves. Seven communities in Xiaoyi have allocated local exploitation, with a planned total area of 335. 14 square kilometers, accounting for 42.8% of the city's proven reserves; Geological reserves 1.509 billion tons, accounting for 2 1.03% of the city's geological reserves.
The coal-bearing strata in xiaoyi city are mainly Taiyuan Formation of Upper Carboniferous and Shanxi Formation of Lower Permian. The total thickness of stratum is about 149 m, the average total thickness of coal seam is 1 1 m, and the coal-bearing coefficient is 8%, of which 1 1 coal seam. Among them, the coal seam of Shanxi Formation is about 55 meters thick, and the lithology is grayish white sandstone, siltstone and sandy shale. Among them, 1, 2 and 3 in the middle are the main minable coal seams, and No.2 coal seam is the main one. No.4 and No.5 coal seams are unstable or relatively stable, which are local minable beds; In Levin and Baibiguan, it is well developed and mining is stable. The coal seam of Taiyuan Formation is about 85 meters thick, and the lithology is gray sandstone, gray-black shale and 3-4 layers of limestone. The lower 9, 10, 1 1 coal seams are all stable and recoverable, mainly 10 coal seam. Levin, Liuwan, Jiaozili and Shuiyu are collectively referred to as Zhangba coal, with a total thickness of 5-6 meters. The upper No.4 and No.5 coal seams are partially exploitable and unstable.
In these coal-bearing strata, the number and thickness of main minable coal seams have changed significantly to the east, west and south. No.2 coal seam of Shanxi Formation in Xiliuwan and Xixinzhuang areas of small powder mining area is partially recoverable. The coal seams of Taiyuan Formation 9, 10, 1 1 are stable in level and thickness, but 10 and1coal seams are often merged into one coal seam.
The distribution law of coal quality in xiaoyi city is that in the horizontal direction, it is rich in the south and thin in the north, and in the vertical direction, with the increase of buried depth, the metamorphic degree gradually deepens. Most of the coal in the south and west is relatively fat, while the coal in the north and northeast gradually becomes coking coal and lean coal. The sulfur content of coal seam in Taiyuan Formation is higher than that in Shanxi Formation. In the total sulfur content, organic sulfur is the most, followed by sulfate sulfur and yellow iron sulfur is the least.
Xiaoyi's coal seam geological structure is relatively simple. Except that the coal seam in Baibiguan mine field is buried more than 600 meters, it is generally buried between 150-350 meters. The main coal seams have stable occurrence, gentle dip angle and easy mining.
Xiaoyi coal reserves 2 By the end of 202 1, there were 670 coal mines in Shanxi Province.
All production coal mines must strictly abide by the relevant laws, regulations, rules, standards and technical specifications of the state, consciously accept the supervision of government departments and the public, and must not produce beyond their capacity. After the main production factors such as coal mine production capacity have changed, they should be changed in time.
