Abstract
The invention provides a microwave plasma adaptive rock breaking device for microwave-insensitive rocks and a using method thereof, and relates to the technical field of rock breaking. The microwave plasma adaptive rock breaking device comprises a microwave system, a microwave plasma conversion system and a cutter head system. The microwave system and the microwave plasma conversion system are mounted in the cutter head system, and the microwave system is connected with the microwave plasma conversion system. Under the premise that only a microwave source is used to supply energy, the combined action of ordinary microwave irradiation and plasma irradiation in the form of high-temperature flame is realized, and a full-section hard rock tunnel boring machine is in cooperation for breaking rocks, so that the problem of microwave-induced cracks of the microwave-insensitive rocks is solved, and the application scope of a microwave rock breaking technology is enlarged.
