Study on Vibration Experiment of Artificial Rock Wall Cutting with Longitudinal Shaft Type Mine Roadheader
Abstract:In order to solve the high vibration range problem of the hard rock cutting with the longitudinal shaft type mine roadheader,an experiment study was conducted on the vibration features.With the establishment of the artificial rock wall and the experiment measurement and test system and according to the actual performances and different operation parameters,a vibration test study on the artificial rock wall cutting with the EBZ315 longitudinal shaft type roadheader.A further analysis was conducted on the vibration data from time domain and frequency domain.The results showed that when the EBZ315 longitudinal shaft type roadheader was cutting hard rock with Protodyakonov coefficient of 8,the max local vibration amplitude would be not over 6g,the integrated vibration amplitude would be small and there was no resonance phenomenon between each parts.All above showed that stability of the mine roadheader was good,the cutting capacity was sufficient and the mine roadheader could be economically applied to the heading of the mine hard rock roadway.
