岩石是采矿工作的对象。在金属矿山的生产过程中,经常遇到的是岩石的破碎与维护;这是采矿工程的基本矛盾,并贯穿始终。生产实践表明,矿山企业生产效率的高低和经济效益的优劣,与岩石爆破特性有关。因此,为了有效地破碎岩石和可靠地维护岩体,提高矿山企业的管理水平,重要的问题是对岩石在爆破过程的特性作出正确的判断,即进行科学的岩石爆破性分级。根据岩石的爆破特性,将其爆破难易程度的序列划分为不同的有限等级,称谓岩石爆破性分级。本文就岩石爆破性分级的模拟实验加以讨论。 Rock is the object of mining work. In the production of metal mines, the rock is often broken and maintained; this is the basic contradiction of mining engineering, and runs through. Production practice shows that the level of production efficiency of mining enterprises and economic advantages and disadvantages, and rock burst characteristics. Therefore, in order to effectively break the rock and maintain the rock mass reliably and improve the management level of the mining enterprise, the important problem is to make a correct judgment on the characteristics of the rock during the blasting, that is to say, the scientific rock blast classification. According to the blasting characteristics of rock, the sequence of its degree of blasting difficulty is divided into different finite grades, which are called blasting grade of rock. This article discusses the simulation of rock burst classification.
