[origin: US6315496B1] The present invention relates to a tunneling method starting from the working face in the driving direction, a bearing layer being laid as the working face progresses and then carried away together with the debris. The inventive system includes at the front an excavating tool capable of removing broken rock up to a certain width and a certain height, and an advancing device for moving forward and steering the system, and a control and setting device for controlling and regulating the operation of the excavating tool and the advancing device.
