Brief introduction of mineral resources development and utilization
I. Overview of Mineral Resources in Delingha City
Delingha city is relatively short of mineral resources. * * * There are 65 mineral deposits in China, 16 species, mainly nonmetallic minerals. The main minerals are limestone, quartzite, dolomite, coal, borax, gypsum, graphite, clay, iron, lead, zinc, gold, silver and copper, among which metal minerals are except Mohe Beitai lead-zinc mine. Energy and mineral resources Wanggaxiu Coal Mine and Baishushan Coal Mine were closed on 1999 due to high ash and sulfur content. Non-metallic minerals are mainly limestone, quartzite and dolomite. Among them, Bai Shu Mountain limestone mine and Wanggaxiu limestone mine are the superior mineral resources in our city, ranking fourth in the country in terms of quality and quantity, with a high degree of resource guarantee. Wanggaxiu limestone mine has proven reserves of 300 million tons, which is a high-quality raw material for manufacturing cement; Baishushan limestone mine, with a distribution area (exploitable area) of about 44 square kilometers, has a recoverable reserve of more than 6543.8+billion tons, with a calcium oxide content of 54-55% and a calcium carbonate content of 95-97%. It is a high-quality raw material for manufacturing soda ash, and its potential economic value is about 3.589 billion yuan. Other nonmetallic mines and large Shi Ying mine 1 have proven reserves of 70 million tons, with silica content of 95-98%. Dolomite for metallurgy 1, proven reserves 1 1.63 million tons.
mineral resources
The exploitation of mineral resources in Delingha began in Wanggaxiu and Baishushan coal mines in 1950s, then began to mine brick clay in 1960s and limestone for cement in 1970s. Mainly based on the exploitation of energy and non-metallic minerals. 197 1, Delingha Cement Plant was put into production and began to mine limestone. At first, the cement production scale was small, and the annual limestone mining capacity was1-20,000 tons. Now the whole enterprise has been acquired by Haixi Chemical Building Materials Co., Ltd. and continues to produce cement, with an annual limestone mining capacity of about 70,000-80,000 tons. 1993, the original Delingha alkali plant was completed and put into operation, and limestone for alkali production was started to be mined, with an annual output of only 20,000-30,000 tons. Until 2000, after being acquired by Meng Xi United Alkali Industry, the output increased year by year. Up to now, the production capacity of soda ash has reached 90,000 tons, and the demand for limestone has reached120,000 tons. Qinghai alkali industry was put into trial production in 2005 and put into production in 2006, which formed the trend of large-scale development and utilization of limestone mines.
geologic structure
Delingha City is located in the northwest of Qinghai Province, and belongs to Qilian Mountain and Qaidam Basin in geomorphologic unit. Geographically, Qaidam basin is a part of Qinling Kunlun Qilian geosyncline fold system and a Mesozoic-Cenozoic depression basin. The banded basement fault along 37 20' in the center of the basin (that is, the foothills of Longshan Mountain in Zongwu) controls the nature of neotectonic movement in the basin. The western part of the basin and the northeastern part of the basin, north of the fault line, have risen slowly since the Tertiary, forming a hilly area dominated by sandstone of the Tertiary and Middle and Lower Pleistocene. The southern part of the basin sinks sharply, which is the main accumulation place of Quaternary, with a thickness of 1200m, forming a piedmont inclined plain composed of Pliocene modern flood, alluvial and lake deposits.
