No.1 mine is located in the mountainous area south of Qitian Mountain in Wuling Mountain area, with steep slopes. It is adjacent to Wu Jia, Guan Chun Township, Meihua District, Lechang County in the south, Yizhang County, Hunan Province in the west, and Shiping, an important town in northern Guangdong on the Beijing-Guangzhou Railway, is 9 kilometers in the north. Nanling railway branch line passes through the mining area, and the highway from Shiping to Shaoguan and Guangzhou passes through the mining department, with convenient transportation.

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.

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.
