高水速凝材料作为一种广泛应用于各种工程实践，特别是矿山采空区充填、巷道支护、隧道塌方充填的新型材料，其物理力学性质越来越受到人们的重视，当其作为充填支护材料时，对其强度特征的研究显得至关重要。同时，当该材料用于采空区充填防止地表沉陷时，由于服务时间长，可能导致材料的长时流变问题，因此研究高水材料结石体强度特征的时间效应是十分必要的。通过研究高水速凝材料强度特征研究，确切掌握强度特征随时间变化的关系。

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.
