A roadway/tunnel excavation robot and an automatic cutting control method are provided. The robot includes a rack, a walking platform, a supporting and stabilizing mechanism, a milling mechanism, a telescoping mechanism, an inclined cutting feed adjusting mechanism, a horizontal swinging mechanism, a lifting mechanism and a controller. The milling mechanism includes a drive unit, a milling shaft, an eccentric rotary casing, a high-pressure jet nozzle unit, a tension and compression sensor and a direction sensor. Through the deflection of a center line of an inner hole of the eccentric rotary casing, the milling mechanism drives a milling cutter head to carry out a rotational oscillation motion for rock breaking. The telescoping mechanism, the inclined cutting feed adjusting mechanism, the lifting mechanism and the horizontal swinging mechanism are controlled such that the milling mechanism performs coal rocks milling.

A tunnel boring apparatus includes a shield body and a cutting disc provided at a front portion of the shield body. The tunnel boring apparatus includes a high pressure liquid device, which includes a liquid storage tank for storing a predetermined amount of liquid, a pressure raising device for increasing a pressure of the liquid, and a plurality of nozzles. The pressing raising device is connected to the liquid storage tank, and to a central rotating head through a first guiding pipeline. The nozzles are provided on the cutting disc, and are connected to the central rotating head through a second guiding pipeline.

The invention discloses a tunnel boring machine (TBM) equipped with a high-pressure water jet cutting system and a combined tunneling method, comprising a TBM body, the water pump unit on the body, and the high-pressure water jet cutting system at the front end of the body. The high-pressure water jet cutting system comprises a water jet-mechanical combined cutter head, water jet-shell knife combined cutters, a high-pressure water pipeline, a multi-medium rotary center, and a water jet diversion valve block. The high-pressure water at the pump unit is transmitted to the multi-medium rotary center through the high-pressure water conveying pipeline, and then divided into multiple paths by the water jet diverter valve block, and respectively supplied to each of the combined cutters on the water jet-mechanical combined cutter head. This invention offers practical suggestions and references for the overall design, and spatial arrangement of the high-pressure water jet cutting system.
