Abstract
ABSTRACTIn order to grasp the laws of dust production from coal cutting and reduce dust production at source by optimizing cutting parameters, the cutting experiments of different brittle coals under different cutting parameters were carried out. Based on the self-developed dust generation simulation platform of road header, the effects of coal brittleness, conical pick top angle, rotational speed, and drilling speed on dust generation were studied, and the main control factors affecting dust generation were analyzed, so as to propose the suitable parameter matching scheme for different brittle coal. The research results can provide an important scientific basis for the premining evaluation of dust production characteristics of mines and the formulation of coal dust control engineering.
