微波辐射技术具有高效性、整体性以及无污染等优点,近年来已成为岩石破碎与成孔应用的热点方向。中外学者运用实验和数值模拟等手段对微波辅助破岩技术进行了广泛研究,并获得了一些有益规律。针对微波辐射岩石的现有研究成果,阐述了微波技术辐射岩石实验进展,明确了微波辐射设备的选型问题,探讨了1.4 kW微波功率条件下辐射玄武岩和石灰岩的实验现象,归纳了微波辐射岩石后裂纹的微观断裂形式及微波辐射裂纹扩展机理,总结了高能微波技术在岩石中成孔应用的进展,以期为高能微波成孔技术在设备及现场工业化应用配套设施研发、多场耦合作用机理、多因素条件评价机制和地下深部“三高一扰动”环境的适用性研究等方向推广应用提供借鉴与参考。

Microwave radiation technology has many advantages, such as high efficiency, integrity and pollution-free, which becomes a hot direction of rock crushing and pore-forming applications in recent years. Domestic and foreign scholars have conducted extensive research on microwave-assisted rock-breaking technology using experiments and numerical simulations, and have obtained some useful laws. According to the existing research results of microwave radiation on rocks, the experimental progress of microwave radiation on rocks was expounded, the selection of microwave radiation equipment was clarified, the experimental phenomenon of radiation on basalt and limestone under the condition of 1.4 kW microwave power was discussed, as well as the microscopic fracture forms of microwave radiation on rocks and the mechanism of microwave radiation crack expansion was summed up, and the progress of high-energy microwave technology in the application of rock porosity was summarized. It is expected to provide reference for the popularization and application of high-energy microwave pore-forming technology in the research and development of equipment and field industrial application supporting facilities, multi-field coupling mechanism, multi-factor condition evaluation mechanism and applicability research of “three highs and one disturbance” environment in deep underground.
