The traditional petri net modeling model cannot obtain the operating state parameter values of the comprehensive coal mining machinery. However, these state parameter values are the input values required by the coal flow adaptive control, which is of great significance to the coal flow adaptive control. Therefore, this paper proposes a state data generation model for comprehensive coal mining ...
Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earth's surface (outcrop). Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s. The earliest coal cutting machines used a .
