Section 2 Overview of Mineral Resources

1. Overview of Mineral Resources

By the end of 2001, 18 types of minerals, including 3 energy minerals, had been discovered in the county. There are 4 types of non-ferrous metal minerals, 2 types of ferrous metal minerals, and 9 types of non-metal minerals. 78 mineral deposits of various types were discovered, including 1 large mineral deposit, 2 medium-sized mineral deposits, 19 small-sized mineral deposits and 56 mineral points. Among them, coal is included in the mineral resource reserves table, and the retained resource reserves of coal and cement limestone rank second in Chenzhou City.

2. Characteristics of main mineral resources

(1) Energy minerals

1. Coal: The county is rich in coal resources. It is mainly distributed in the Yuanjia mining area. The ore-bearing layer is the Longtan Formation of the Upper Permian. It is divided into 10 mine fields and is located in 9 towns including Shiqiao, Xiaojia, Xinglang, Longtan, Yuanjia and Tangcun. By the end of 2001, Yuanjia Mining Area had 126 million tons of coal reserves (basic reserves of 106 million tons, resource volume of 20 million tons), ranking second in Chenzhou City. The average minable thickness of the minable coal seams was 3.91 meters, led by anthracite coal. Mainly, the coal quality is good and the exploration level is high.

2. Uranium: 1 proven location is located in Nantou, Xiaojia Town. It is a large-scale mineral deposit. It is produced in the bioclastic limestone in the lower section of the Shidengzi Formation of the Lower Carboniferous System. It is one of the unique mineral deposits in our county. Energy minerals with great potential.

(2) Non-ferrous metal minerals

1. Copper: 1 small deposit has been discovered, located in Huangsha Temple, Longtan Town. The ore resource reserves are 506,700 tons, the average copper grade is 2.42%, and the metal content is 12,300 tons. The associated minerals include lead (metal content: 4,000 tons) and zinc (metal content: 2,700 tons), which have not yet been developed and utilized.

2. Lead and zinc: ***There are 5 mineral sites located in Guangtang, Zhumushan, Shiguyuan, Nanling Forest Farm and Wang Yangfu in Longtan in Panjiang Township, but no deep mining has been done. Geological exploration work has not yielded reliable geological reserves.

3. Mercury: There are 5 mineral sites, distributed in Jinglin and Pingtianpu of Chetou Town, Hantian of Chengguan Town, Xixi and Datang of Guangfa Township, etc. Only Chetou has reached the level of census work. Jinglin Mercury Mine has discovered resource reserves of 22,400 tons (metal content of 15.76 tons). The ore body is mainly found in the dolomite of the Mengong'ao Formation of the Carboniferous System and is a low-temperature hydrothermal deposit.

(3) Ferrous metal minerals

1. Iron: Except for the three towns of Chengguan, Tanping and Lianhe, iron ore has been found in the remaining 14 towns. Preliminary exploration of the ore Point 24. The resource amount is 21.4 million tons, and the average grade is about 32%.

2. Manganese: Except for the five towns of Chengguan, Tanping, Lianhe, Panjiang and Guangfa, manganese mines have been found in the remaining 12 towns, and 14 mineral spots have been found in preliminary inspections. Manganese ore resources are 4.38 million tons, with an average grade of about 24%.

(4) Non-metallic minerals

1. Dolomite: distributed in Panjiang, Yuanjia, Zhongshui, Shiqiao, Pantou and other towns, with predicted resource reserves of 250 million tons The above has great development and utilization value.

2. Limestone: It is exposed in 17 towns and villages in the county. The predicted resource reserve is 4.5 billion tons, ranking second in Chenzhou City. There are 3 large-scale limestone deposits with good development and utilization prospects.

3. Bricks, tiles and clay: spread across 17 towns and villages in the county, with rich resource reserves.

Section 3 Current Status of Mineral Resources Exploration

1. Basic Geological Work

Completed 1/200,000 regional geological survey and regional hydrogeological survey, 1/ 200,000 geochemical survey and 1/1 million, 1/500,000, 1/200,000 aeromagnetic survey and regional gravity survey. The 1/50,000 regional geological survey*** has completed 466.33Km2, accounting for 66.69% of the county's total area.

II. Mineral geological work

78 mineral deposits of various types were discovered in the county, including 2 exploration sites, 5 detailed surveys, 13 general surveys, and 58 preliminary surveys. The highest degree of geological work.

Section 4 Current Development and Utilization of Mineral Resources

In 2001, 6 types of minerals were developed and utilized in the county, and there were 159 mining companies, including 7 state-owned mines, 17 collective mines, individual and There are 135 joint-stock mines. There are 7,920 employees, of whom 82.39% are engaged in the coal industry and 17.61% are engaged in the non-metal industry.

The annual output of solid ore is 1.72 million tons, of which coal accounts for 77.09% and non-metallic minerals account for 22.91%. From the analysis of the total industrial output value of various mines, coal production in the county occupies a dominant position, accounting for 88.12% of its total industrial output value, and non-metallic mines account for 22.91%. 11.88%. The total output value of mining is 234 million yuan, accounting for 13.85% of the county's GDP. Mining has become a pillar industry of the county's national economy.

At present, the minerals developed in our county’s mining industry include coal, cement limestone, limestone for building stones, marble, clay and river sand. Although other minerals have been mined, they are all mined sporadically.
