Abstract: В работе дан анализ результатов экспериментального исследования разрушения крепких горных пород инструментом с вращающейся режущей частью.
Description: The article deals with the important problem of developing a cutting tool which would provide the cutting of both coal and hard rock. We analyze the results of experimental research of hard rocks destruction by means of a tool with rotating cutting part. Based on experimental data we considered the influence of such geometrical parameters as diameter and cutting-point angle of a tool, width and thickness of the slice upon the value of efforts and specific power consumption in the process of hard rock destruction. We found out that minimal value of specific power consumption during rock destruction using the abovementioned tool can be observed when the relation between the slice width and thickness is 3 and 4, while the guaranteed destruction of a pillar between cutting direction lines corresponds to 2,5 to 3. The diameter of a tool has a great influence on the effectiveness of pillar chipping and specific power consumption as due to its growth the specific power consumption gets lower, and the effectiveness of pillar chipping is deteriorated. At the same time the reduction of the tool’s cutting-point angle has a slight influence on specific power consumption of destruction process, however it improves the effectiveness of pillar chipping.
