微波辅助滚刀破岩具有较强的应用前景，为深入分析微波照射对滚刀破岩的辅助效果，进行了微波照射后的TBM缩尺滚刀破岩试验。通过使用不同参数的微波照射岩石，研究了不同微波参数对岩石表面温度的影响规律。在岩石恢复室温后，以微波照射的岩石为基础，开展TBM缩尺滚刀旋转破岩实验，研究微波照射时间和功率对滚刀推力、刀盘扭矩、岩碴重量、滚刀磨损量以及破岩比能的影响规律。结果表明：随着微波照射时间和照射功率的增加，岩石表面温度增加，岩石升温速率增加，岩石表面最高温度为172.6 ℃；滚刀推力在破岩中呈波动变化，滚刀下方岩石被碾压为粉末，滚刀侧方产生块状岩碴；随着微波照射时间和微波功率的增加，滚刀推力下降、刀盘扭矩下降、岩碴重量增加、滚刀磨损量下降、破岩比能下降。对于试验所使用赤峰玄武岩最佳微波照射时间应大于40 s、微波功率应大于7 kW。为微波辅助滚刀破岩提供了一定的试验依据。

Microwave assisted cutter breaking has a strong application prospect, in order to deeply analyse the auxiliary effect of microwave irradiation on cutter breaking, the TBM scale cutter breaking test after microwave irradiation was carried out. Firstly, the rock was irradiated by microwave using different parameters, and the influence law of different microwave parameters on the surface temperature of the rock was studied. After the rock is back to room temperature, the damaged rock was taken as the basis to carry out the TBM scale cutter rotary rock breaking experiment, to study the influence of microwave irradiation time and power on the cutter thrust, cutter torque, rock ballast weight, cutter wear and the specific energy of rock breaking. The results show that: with the increase of microwave irradiation time and irradiation power, the rock surface temperature increases, the rock heating rate increases, the highest temperature of the rock surface is 172.6 ℃. The cutter thrust is fluctuating in the breaking rock, the rock below the cutter is crushed to powder, the cutter side produces block ballast. With the increase of microwave irradiation time and microwave power, the cutter thrust decreases, the disc torque decreases, the weight of the rock ballast increases, the amount of cutter abrasion decreases, and the specific energy of rock breaking decreases. The best microwave irradiation time should be more than 40 s and the microwave power should be more than 7 kW for the test of Chifeng basalt, which provides a certain experimental basis for the microwave-assisted cutter rock-breaking.
