了解材料的基本物理量，对评价该材料的使用价值及使用效果具有十分重要的意义，并且有助于分析材料的强度特征与力学参数。因此在研究高水速凝材料的强度特征与力学性质之前，有必要对其基本物理参数进行测定。高水速凝材料的基本物理参数包括结石体重度、浆液重度、含水率、孔隙率、渗透系数、初凝时间等，本次实验主要测定材料的重度、含水率以及初凝时间。
瞭解材料的基本物理量，對評價該材料的使用價值及使用效果具有十分重要的意義，併且有助于分析材料的彊度特徵與力學參數。因此在研究高水速凝材料的彊度特徵與力學性質之前，有必要對其基本物理參數進行測定。高水速凝材料的基本物理參數包括結石體重度、漿液重度、含水率、孔隙率、滲透繫數、初凝時間等，本次實驗主要測定材料的重度、含水率以及初凝時間。

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.
