Yangbajing is located in south-central Xizang Autonomous Region, in the southwest of Nyainqentanglha piedmont fault basin, 90km north of Lhasa, in Dangxiong County. Yangbajing is a Tibetan place name translated from Chinese characters. It means vast. Yangbajing, at an altitude of 4,300 meters, is a basin with an area of about 40 square kilometers. The geothermal field is located in the middle of the basin, with an area of 17. 1 km2. It is a high temperature and wet steam geothermal field. Hot springs, hot springs, boiling springs, spray holes, hot pools, thermal explosion holes and steam fields are everywhere in the thermal field. The hydrothermal temperature generally reaches 93℃- 172℃, and some reach as high as 200℃. Natural heat flow per second
It is 1 10000 kcal, and the heat released in the whole year is equivalent to burning 470,000 tons of standard coal, and the thermal power generation potential is about.
Up to 1.5 million kilowatts. More than 40 production wells have been drilled. Yangbajing Geothermal Test Power Station has three generating units, and the total installed capacity has reached 1.9 kW. The electricity generated by Yangbajing Geothermal Power Station is transmitted to Lhasa through 1 10000 V high-voltage transmission line, which greatly relieves the power shortage of Lhasa's industry, agriculture and residents. Although China's Guangdong, Hebei, Jiangxi, Hunan, Shandong, Liaoning and other provinces have also built geothermal power stations, from the perspective of rich geothermal resources and power station scale, Tibet Yangbajing ranks first. Yangbajing Geothermal Experimental Power Station is the largest geothermal power station in China.
The hydrothermal explosion of Yangbajing occurred in the south of the hot field and has been discovered three times. Telephone 1977 12
The hot water explosion at 2 pm on April 4th lasted for about 3 minutes, causing 5 tents to be destroyed and 1 person injured. Just then, there was a loud noise, and a thick column of black smoke with a height of 50 meters and a diameter of 10 meter went straight into the sky.
25-30 cm stones were washed into the sky, carrying a lot of sediment steam and water.
Jet violently. Intense hot water activities and the snowy peaks towering in the blue sky set each other off, which can be called the wonder of "the roof of the world".
There is a hot water lake in Yangbajing, which is the product of a large-scale hydrothermal eruption. The plane of the lake is slightly oval, and the long axis is close.
North-south direction, the length is about 1 10 m, the short axis is about 80 m, the lake area is about 7350 square meters, the maximum water depth is 16. 1 m, the hot water rises from the deepest place, the color of the hot water lake is blue, and the temperature of the lake is between 45℃ and 59℃.
The development and utilization of geothermal resources in Yangbajing is listed as a key scientific research project by the relevant state departments.
With the development of science and technology, the wisdom and ability of human beings to conquer nature will become stronger and stronger, and the development and utilization of geothermal resources in Yangbajing is still promising.
