摘要
随着我国资源开发逐步进入深部开采阶段,深部高硬度岩(矿)石对目前地下工程中岩石破碎提出了新的挑战,各类新型破岩手段应运而生。高压水射流破岩、微波破岩以及液氮低温破岩作为三种热门新型破岩方法已被广泛研究,三种破岩方法的发展历程、工作原理以及适用场景各不相同,但是均具有广阔发展前景。在未来深部坚硬岩石地层环境中,相关研究成果以及理论方法可以为安全、高效、经济及绿色的资源开发提供一定理论基础与技术支撑。
With the exploitation of underground resources gradually entering the stage of deep mining,the high hardness rock(ore)in deep mining process poses a new challenge to rock crushing in underground engineering at present,therefore various new rock breaking means begin to emerge.High pressure water jet rock breaking,microwave treatment rock breaking and liquid nitrogen low temperature rock breaking as three popular new rock breaking methods have been widely and deeply studied by domestic and foreign scholars.The development history,working principle and application scenarios of these rock breaking methods are different,but all three rock breaking methods have broad development prospects.In the future deep hard rock formation environment,relevant research results and theoretical methods can provide theoretical basis and technical support for safe,efficient,economic and environmental underground resource development.
