在解决许多对采矿工程实践很重要的问题时,例如评价地下巷道和露天矿场边坡的稳定性或提高在岩石中的开挖和钻进速度时,岩石强度特性的知识具有首要的意义。所谓强度,简单地说就是岩石对各种方式的外力作用的抵抗能力,例如对于压缩荷载作用的抗力就叫抗压强度,对于拉伸荷载作用的抗力就叫抗拉强度等。在采矿工程中,一般把岩石的强度看作是岩石坚固性的指标之一,给予了充分的注意和研究。但由于岩石的复杂性以及试验研究中一些唯心主义和形而上学的影响,在对岩石强
Knowledge of the strength characteristics of rocks is of primary importance when addressing many issues of importance to mining engineering practices, such as the stability of underground tunnels and open pit slopes or the improvement of excavation and drilling rates in rock. The so-called strength, simply is the rock’s resistance to external forces in various ways, for example, the compressive load resistance is called the compressive strength of the tensile load for the resistance called tensile strength. In mining engineering, rock strength is generally regarded as one of the indicators of rock solidity, giving adequate attention and research. However, due to the complexity of rocks and the impact of some idealism and metaphysics in experimental studies,
