Abstract

An insensitive rock microwave plasma self-adaptive rock breaking device and a method for use thereof relate to the technical field of rock breaking, including a microwave system, a microwave plasma conversion system and a cutter head system; the cutter head system is provided with a microwave system and a microwave plasma conversion system system, and the microwave system is connected with the microwave plasma conversion system. Under the premise that only 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 the full-section hard rock tunnel boring machine is used for rock breaking, which solves the problem of microwave cracking of microwave-insensitive rocks, and increases the The scope of application of microwave rock breaking technology is introduced; the plasma torch is used to heat the rock at high temperature, and the ordinary microwave irradiation method solves the microwave cracking problem of the rock that is insensitive to microwave at normal temperature but sensitive to microwave at high temperature.

Description

technical field [0001] The invention relates to the technical field of rock crushing, in particular to an insensitive rock microwave plasma self-adaptive rock-breaking device and a method for using the same. Background technique [0002] Among the many rock-breaking technologies, mechanical rock-breaking and drill-and-blast construction are the two most commonly used. Compared with traditional drill-and-blast construction, mechanical rock-breaking has the advantages of less disturbance to surrounding rock and high construction accuracy, especially for all rock-breaking techniques. Cross-section hard rock tunnel boring machines have been widely used in tunnel engineering. However, the hard nature of rock will lead to serious wear of the full-face hard rock tunnel boring machine tool, and the driving speed will be greatly reduced. [0003] In the past half century, many new auxiliary rock-breaking technologies have been developed, such as laser rock-breaking, high-pressure wa...
