Abstract: EBH315 Roadheader is a hard rock roadheader specially used for large cross-section roadway drivage. In order to test whether it has reached the design level and actual cutting ability, and is better used in actual roadway excavation in coal mine underground, a simulation test of false rock wall cutting was carried out. During the test, the cutting motor power, hydraulic system pressure and flow change curve, vibration of the whole machine and stress change in key parts of the machine under different cutting parameters were recorded. Through sorting and analyzing the test data, the measured data of the whole machine parameters of the roadheader are obtained, so as to verify the design parameters of the roadheader. At the same time, valuable experimental data are provided for the design and research of the roadheader, which can effectively guide the subsequent improvement of the design work.
