To the problem of improvement the working tools of mining excavation machines

Investigation of the Process of Incisor Formation by the Planetary Disk Executive Body of a Tunneling and Cleaning Combine

“…Рациональные параметры процесса формирования резов резцами исполнительного органа на открытой поверхности горного массива определяют развитие и распространение трещин, а также форму элементарного скола в его поперечном сечении [9,10], что сказывается на выходе необогатимых пылевидных фракций в отбитой руде. Установлено, что применение шахматного резания с рациональными параметрами позволяет снизить выход мелких фракций [11].…”

Tangential rotary picks: Wear modeling and reusability evaluation

“…According to Dosco manufacturer of continuous miners, the amount of picks in operation in coal and sandstone having V com = 100 MPa reaches 300 m 3 /pick in coal and 3 m 3 /pick in sandstone [21]. Based on these data, it is predicted that the life time of the test pick model RSG in strong sandstone makes 1-2 operating shifts.…”

“…As a subject of scientific research and further improvement, tangential rotary picks of cutting and shearing machines interest researchers in many countries [1][2][3][4][5][6][7][8]. The recent studies focus on the development and justification of a composite design of the tool and its modifications.…”

“…Installation of such conveyors meant for high lifting of load requires setting a few standard flights, which involves investing in much stone development drivage. At the same time, the installation of a conveyor line composed of a few belts at overload chops availability of the equipment and increases its failure probability [2][3][4][5].…”
