With respect to the serious environment problems of coal mining, a new concept of green mining is proposed. The goal is to maximize the economic and social benefits. The technical framework of green mining includes water-preservation in mining areas, coal mining to retard surface subsidence, simultaneous extraction of coal and coal-bed methane, reduction of rock waste, underground coal gasification, and others. The natural climate in Northwest in China is very odious, and its geological condition is very complex. The precipitation is less and concentrated. Drought and water logging in the area are very usual to see, and the eco-system is very weak. Water resources in the area are limited. The eco-environment problems such as desertification,loss of soil,mud-rock flow, earth slide, land degeneration and decrease of cultivation area are quite common in the area. In the meantime disorder exploitation of coal mine in the area has made the geological environment and ecology system more fragile. Based on analyzing the problems in detail, his paper puts forward green mining in the areas.
