在印度,深露天矿正在引起人们的关注。十年内,拉贾斯坦磷矿的开采深度将达地表以下约130～140米。过去,许多矿山是根据经验设计的。当岩体几何形状变化时,一些矿山发生大滑坡。在规划和设计这些矿山时,研究岩石的动态弹性常数并预测其特性是非常重要的。在众多的岩石动态特性研究方法中,声波速度法因简便和快速而在现场和实验室都得到了广泛应用。通常采用此法研究岩石的动态特性,包括确定岩石的
In India, deep-open mines are arousing public concern. Within a decade, the mining depth of the phosphate rock in Rajasthan will reach about 130 to 140 meters below the surface. In the past, many mines were designed empirically. When the rock geometry changes, a number of large landslides occurred. In planning and designing these mines, it is important to study the dynamic elastic constants of rock and predict its properties. Among numerous research methods of rock dynamic properties, the acoustic velocity method has been widely used in the field and in the laboratory due to its simplicity and speed. This method is usually used to study the dynamic characteristics of rocks, including the determination of rock
