The mountainous area of Mohe County is rich in mineral resources under the complex geological structure and the internal and external forces of many orogenic movements. From the discovery of gold deposits in Xianfeng County in Qing Dynasty to 1990, working people have known and exploited minerals for more than 100 years. In the early years of Guangxu, the Mohe gold mine was stolen by Russian colonists. After Lunwa in Mohe County, the Japanese plundered the mineral resources of China. After exploration, mining and geological drilling in recent years 100 years, by the end of 1990, the minerals discovered in China are placer gold, coal, limestone, mica, perlite, graphite, diorite, bentonite, clay, zeolite, quartz sand, pyrite, marble, lead, peat and magnetic pyrite-green. There are 55 deposits, belonging to 7 industrial types. Among them, a few such as gold, coal and limestone have been developed and utilized. Mohe county is one of the important gold producing areas in China. Mining has a long history and produces a lot of gold. Since the Guangxu period in the late Qing Dynasty, after Russia expelled the gold bandits, it was nationalized, and the gold output once surpassed Zhaoyuan County, Shandong Province, which was known as the golden land in the Five Dynasties, ranking first in the country. 1985- 1986, which has been ranked among the top 100 gold-producing counties in China for two consecutive years. The main gold mines are located in Laogou, Fukeshan, Varukuto, Xinghua, Gulian, Jiawuke, Madar, Longgou, Maniqi, Dalin, Qiaqi, Jixingou and Indaluqi in Gil. The county's estimated reserves exceed 65.438 million tons, and industrial reserve has 50 tons. By the end of 1990, the county's proven reserves were 40.5 tons, and the distribution of reserves is as follows:
1. Laogou 2.7 tons
2. Fokker Mountain 4.5 tons
3. Varukuto River 2.7 tons
4. Xinghua ditch 0.7 tons
5. Gulian River 4.0 tons

Folding coal mine
Mohe is rich in coal reserves and is a famous coalfield in Huola Basin. In addition, outcrop signs were also found in the application areas of Hedong Forest Farm and Outpost Forest Farm. In addition, five coal mines were discovered in the west bank of the middle reaches of amur river.
Folding Gulianhe Coal Mine
1973 started construction and was named gulianhe coal mine. The mining area is located in the exploration area of Yueya Lake in Huolapen coalfield, coalfield forest farm, Shi Ye District, Xilin Gol League, Mohe County. Geographical coordinates are 12 1 degree 58 minutes east and 53 degrees 04 minutes north. During the exploration in recent two years (1987- 1979), B+C+D reserves were 50810.5 million tons, and A+B+C reserves were 48.045 million tons in 1983. The exploration area is 10 square kilometer, 4 kilometers long from east to west and 2.5 kilometers wide from north to south. The eastern part of the mining area is 365,438+0km away from Gulian East Station of Nenlin National Railway and 532km away from Jiagedaqi. The highway from the mining area to Gulian has been completed, with convenient transportation.
According to198365438+February, Northeast Inner Mongolia Coal Industry Joint Company and Shenyang Coal Mine Design Institute provided information; The coal seam of Gulianhe Coal Mine contains five layers of coal, numbered from top to bottom as 1, 2, 3, 4 and 5. Among them, No.2 coal seam is the most stable and the main mining object in the mining area, and the rest coal seams are partially recoverable. The average thickness of coal seam is11.3m. ..
