摘要

摘要: 为了提高采煤机滚筒的装煤性能和工作效率，基于PRO/E、EDEM、MATLAB联合构建了新型薄煤层采煤机截割部离散元仿真模型，模拟了采煤机截割、破碎煤岩的复杂过程，并获得了相应的装煤率；基于单因素分析法，研究了牵引速度、滚筒转速及截深对采煤机装煤率的影响规律；利用多因素分析法研究了各因素对采煤机装煤率影响的显著程度，并得到了使其装煤性能最优的设计参数。研究结果表明：基于实际工况，新型薄煤层采煤机装煤性能最优的设计方案为：滚筒截深为700 mm，牵引速度为9 m/min，滚筒转速为58 r/min，为采煤机滚筒装煤性能的研究及优化提供了一种新方法。

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.
