Abstract

A tunneling and anchoring machine () and a tunneling system, the tunneling and anchoring machine () comprising a rack (), a cutting device (), a drilling device () and a control device; the cutting device () has a lowest swing angle (B) and a highest swing angle (α); the drilling device () comprises a drilling machine () and a sensor, the sensor is electrically connected to the drilling machine (), the drilling machine () is suitable for drilling a roadway floor and/or a roadway roof, and the sensor is suitable for, when the drilling machine () is drilling, monitoring a set parameter of the drilling machine () and generating a monitoring data signal; the sensor is electrically connected to the control device, and the control device is suitable for receiving and analyzing the monitoring data signal; when the drilling machine () drills a first thickness of the roadway floor, if the monitoring data signal is greater than a first threshold, the control device is suitable for adjusting the lowest swing angle (β); and when the drilling machine () drills a second thickness of the roadway roof, if the monitoring data signal is greater than a second threshold, the control device is suitable for adjusting the highest swing angle (α).
