矿用高水速凝材料结石体材料强度的快速测定方法

A Rapid Method for Determination of Strength of Mine High Water Quick Hardening Material Stone Material

材料强度的快速测定方法是指采用简单便携仪器,在工程现场测定材料使用时的强度,此方法可以避免取样、制样、测试等实验室测试的复杂环节,有助于在工程现场得以推广应用。高水材料强度的快速测定方法正是满足于工程现场强度的快速测定,使得强度参数测定变得快捷、简单、方便,因而对该方法的研究十分有必要。

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.
