Experimental Study on the Influence of Cutting Parameters on the Dust Production Characteristics of Roadheader
Mine dust,as one of the most serious underground disasters,not only threatens the mine production but also affects the respiratory health of the operators.In order to effectively reduce the amount of dust in roadway boring,different cutting parameters of the cutter teeth of the roadheading machine were studied,and it was found that the larger the relative angle between the cutting direction of the cutter teeth and the contact surface of the coal body,the more obvious the effect of the reduction of mine dust;the effect of the cutting speed on the characteristics of the dust production was considered to be basically negligible under laboratory conditions.The research results can provide some guidance for the idea of dust reduction in the face of digging.
