Years of emphasis on the development of underground equipment have left the surface coal mining sector lacking in modern, domestically built, high-capacity machines. According to the Soviet coal industry, the following equipment is needed to meet the ambitious production increases planned for the future: (1) 20 cubic meter (26 cubic yard) shovels; (2) 12.5 and 20-cubic-meter (16 and 26-cubic-yard) hydraulic excavators; (3) bucket wheel excavator systems with capacities of 5250 and 12,500 cubic meters (6800 and 16,300 cubic yards) per hour; (4) drill rigs for hole diameters from 320 millimeters (13 inches) to 1 meter (39 inches); (5) 110 and 180-ton-capacity trucks; (6) conveyor systems with capacities of 10,500 cubic meters (13,700 cubic yards) per hour; (7) thyristor converters for main drives, electronic control systems, and electrical equipment for large draglines and bucket wheel excavators; (8) high-strength large-diameter steel rope; (9) hydraulic drives and systems; (10) non-flammable hydraulic fluids; and (11) air-conditioning systems for operator cabs. There is no doubt that the Soviets have the inventiveness, ingenuity, and resources to design and supply this equipment themselves. What they may be lacking is time. If the set targets are indeed to be met, then the industry will have to buy from abroad.
