The Environmental problems in large-scale metal mine areas have become one of factors, which constraining the harmonious development of mining cities. Baiyin city, located in the middle of Gansu Province, is a famous Copper City in China, an old industrial base and the biggest non-ferrous metal industrial base. But there exists a series of environmental geological problems. Waste gas, water and residue have heavily polluted the mine and surrounding ecological environment, which has influenced the health of the surrounding people, has constrained the further development and exploitation of the mineral resources from the mines. Based on the special environmental problems in the mine, it is proposed to carry out some countermeasures to rebuild and improve the ecological environment: to apply a clean produce technology to control and lower the pollution discharge, to apply advanced reclamation technologies to rebuild and improve the polluted environment, to strengthen the scientific research and international cooperation, and to develop a circular economy in mines.
自东太平洋海隆(EPR)21°N首次发现高温热液喷口(Francheteau et al.,1979;Spiess et al.,1980)以来,沿EPR发现了一系列活动热液喷口和硫化物矿床。大量热液活动调查研究表明不同喷口热液流体化学特征具有很大相似性(Von Damm,1990;Von Damm et al.,1995),例如最早报道的加拉帕格斯裂谷热液流体3He/4He比值具有很好的一致性(Lupton et al.,1977;Jenkins et al.,1978)。
