薄煤层采煤机装煤性能影响因素分析
Analyzing Factors of Influence on Loading Performance of Thin Coal Seam Shearer
摘要
Abstract
In order to enhance the loading performance and efficiency of a thin coal seam shearer,the discrete element simulation model of its cutting unit was constructed based on the PRO/E,EDEM,MATLAB.The complicated coal rock cutting process of the shearer was simulated;the corresponding loading rate was obtained.The law of influence of traction speed,roller speed and cutting depth on the shearer's loading rate was studied based on the single factor analysis method.The various factors of influence on the shearer's loading rate were studied with the multi-factor analysis method,and the optimal design parameters of the loading performance were obtained.The study results show that,based on the actual working conditions,the optimal design scheme of the new thin coal seam shearer for enhancing its coal loading performance is:the cutting depth of the drum is 700 mm;the traction speed is 9 m/min;the roller speed is 58 r/min;the loading rate is 26% higher than before optimization.The results provide a new method for the research and optimization of coal loading performance of the shearer's drum.关键词
