The main resource of this mine is bituminous coal. In the 26th year of the Republic of China (1937), on April 24th, businessman lin li opened a coal mine in Zhangjiashan, Guan Chun. In 3 6 years of the Republic of China (1947), on August 2 1 day, Yuan started a revitalization company in Simaowo, and local farmers dug holes. After the establishment of People's Republic of China (PRC), Nanling Coal Mine was built in Guan Chun on 1954. At first, the +2 16m north adit was mined, which was put into production in July of that year and ended in the autumn of 1959. Open +2 16m south adit at 1955. In June 1958, the south inclined shaft and the north inclined shaft were developed respectively. In June 1959, the production was put into operation, and the mining level was extended to+130m. 1967 north inclined shaft is extended to+50m horizontal mining, 1970 south inclined shaft is extended to+50m horizontal mining, 1972 connects two wells through+50m floor roadway. 1February, 969, the mine construction team developed Guanchun No.1 and No.2 wells, and the mining depth of No.1 well was -65 meters. The mining depth of No.2 well is-200m. The designed annual production capacity is 90,000 tons. 1975-65m horizontal development of south dark inclined shaft, designed to connect with -200m horizontal vertical shaft, the shaft was flooded when it was dug to-170m elevation, and the mine resumed production on 1976 and was closed. 198 1 May-65m north dark inclined shaft development. In the process of shaft extension,-130m temporary horizontal mining was carried out. Later, all the main and auxiliary shafts extended to-200m level and entered the northern wing of this level for mining. 1989, the annual production capacity of No.1 Mine was approved as 1 10000 tons. From 1954 to 1990, the total coal output is 4367 1 10,000 tons, and the highest annual output 1979 is 203,000 tons.
On July 1990 and 12, the Provincial Coal Industry Corporation approved the implementation of non-closed curtain grouting water plugging project in limestone with floor in this mine, and organized the construction under the guidance of the water control engineering headquarters of this bureau.
1990, the whole mine produces raw coal 139800 tons, with 984 employees. Main technical and economic indicators: overall work efficiency is 0.626 tons/work, mining efficiency is 2.560 tons/work, tunneling efficiency is 0.325 meters/work, raw wood consumption is 97.43 cubic meters/ten thousand tons, raw steel consumption is 3.8 1 ton/ten thousand tons, raw coal pulverized coal consumption is 1.743 kg/ten thousand tons, and raw coal. At the end of the year, the production capacity of the mine is 1 654,38+0,000 tons/year, the guaranteed reserves are 3.228 million tons, the remaining recoverable reserves of the mine are 558,000 tons, and the three coal quantities for development, preparation and mining are 1 6555550 tons, 27,900 tons and/kloc respectively. No.2 Mine is located in Xiushui District, Lechang County, at the junction of Hunan and Guangdong in Nanling Mountains. There is a special line from Pingmei Branch Line to Huoshaoping, which is 3 kilometers away from the coal mine. The coal mine has a light electric locomotive to Huoshaoping, and another road running through the mining area can lead to Yizhang, Hunan, Lechang and Ruyuan, Guangdong.
Baziling started mining in 7 years of the Republic of China (19 18). In the 24th year of the Republic of China (1935), Peyo Industrial and Mining Company continued to exploit small shallow molds. The first and second adits were mined before 36 years of the Republic of China (1947). At that time, due to inconvenient transportation, insufficient funds and the influence of war, it stopped many times. The mine has experienced many periods such as Peyo Industrial and Mining Special Co., Ltd. and Nanling Coal Mine Co., Ltd.
1949 10 after the liberation of Nanling coal mine, the production continued to develop and three or four adits were opened. 195 1, with more than 270 employees and an annual output of 7402 tons of raw coal. 1953, baziling mine was renamed baziling pit. Five adits were opened that year, and the annual output of raw coal rose to more than 50,000 tons.
Due to unclear geological resources, Baziling work area was dismounted on April 1957. July 1958 resumed production, and the main and auxiliary shafts of concealed inclined shafts started construction, and a small coal transportation railway from Huoshaoping to Baziling was built. 1959 The coal output was 27,000 tons, and the number of employees 1500 people. 19 60 produced 59,000 tons of coal, 1960, 10 After the establishment of Shi Ping Mining Bureau, Baziling work area was renamed Nanling No.2 Mine, with Baziling work area and Shangliao work area under it, with an annual output of 54,000 tons. By 1962, due to the small reserves, the output decreased, and a number of employees were reduced, leaving more than 700 people. 1963, Nanling No.2 Mine was renamed Baziling Work Area with an annual output of 2.9 tons. After 1965, the output gradually increased, with an annual output of about 70,000 tons. 1970 has 853 employees and an annual output of over 654.38+10,000 tons. On the evening of May 2, a flooded well accident occurred in the excavation of 1972 and 12 +60 west lane, and the production was stopped for more than three months. 1973 auxiliary shaft of dark inclined shaft is extended to +60 level, and the main auxiliary shaft is produced at the same time, with a production capacity of 90,000 tons/year. 1977 Newly started inclined shafts and vertical shafts with a production capacity of 90,000 tons/year. 1980 open inclined shaft and deliver it to production first. The second mine was repeated twice and three times, with the increase and decrease of personnel and the increase and decrease of output. From 1949 to 1990, a total of 3,527,200 tons of raw coal were produced, with the highest annual output of 1979 and166,500 tons.
1990, the whole mine produces raw coal 132500 tons and employs 1256 people. Main technical and economic indicators: the overall efficiency is 0.54 1 ton/work, the mining efficiency is 2.567 tons/work, the tunneling efficiency is 0.193m/work, the log consumption is 104. 17 m3/10,000 tons, and the raw steel consumption is 2.7/kloc. At the end of the year, the mine production capacity 1 1 10,000 tons/year, the retained reserves1956,000 tons, and the remaining recoverable reserves of the mine were 867,000 tons. The amount of coal developed, prepared and mined is 362,200 tons,126,300 tons and 64,800 tons respectively. No.3 Mine is located in Zengjialiao, Guanxi Township, Yizhang County, Hunan Province, 28 kilometers northeast of Guanchun (railway) and about 40 kilometers north of Yizhang City (railway). There is a special railway line from the coal bunker in the mine to Shiping Station of Beijing-Guangzhou Railway, with a total length of 36.55km, passing along the Dog (Dog Tooth Cave) Bao (Baogong Temple) Highway 1 1.2km?
The Kansai ore field was discovered more than 100 years ago, and there are caves everywhere. In the third year of the Republic of China (19 14), Chen Lianbo, a Guangdong businessman, opened the Gouyadong Mine of Dili Company in this area. At 1950, Ermao, a local farmer in Yu Jia village, hired more than 20 people to dig a pit near Kansai tail for his master. 1952 autumn, Nanling Coal Mine took over the earth caves and most of the farmers who dug holes, set up the Kansai section (later changed to the work area), and opened up the Kansai adit and inclined shaft. 1958 dismounted in May. 1959 kansai inclined shaft resumed production, with about 500 workers. 1960 10, Nanling Coal Mine belongs to Shiping Mining Bureau, Guanxi Industrial Zone is changed to Nanling No.3 Mine, and the mine department is located in Gouyadong. Dismount again at 196 1. 1In April, 1966, Zengjialiao rebuilt Guanxi Industrial Zone,1In February, 1966, Zengjialiao developed a +240 level adit. From 1969 to 1970, an open-pit inclined shaft and a small shaft were successively dug in the gully cave to communicate with the +240 adit. The adit was put into production in June of 1974+00, and the designed production capacity is120,000 tons/year. In order to continue production, the inclined shaft will be gradually mined from +240m level. To 19 90, the concealed inclined shaft is extended to-170m level. 1952 to 1990, raw coal 1927800 tons, and the maximum annual output is 153700 tons.
1990 the whole mine produces 95,200 tons of raw coal, with 1 123 employees. The main technical and economic indicators are: the overall work efficiency is 0.397 tons/work, the mining efficiency is 2.247 tons/work, the tunneling efficiency is 0. 193 meters/work, and the raw coal wood consumption is 122.
