This design is reaches the luxuriant iron ore opencut mining the craft and the development design, the annual output 2,000,000 tons. Uses the boundary to pick exhaustedly compares is not bigger than the economy reasonable picks exhaustedly compared to the principle to select the opencut mining boundary. And carries on the recoverable resources and the average picks the ratio exhaustedly the computation. Extends the deep speed confirmation productivity with the mine. When establishment strip mine excavation progress schedule, the average picks exhaustedly compared to rides the coefficient the method initially surely to produce picks exhaustedly compared to, power shovel's efficiency basis similar mine selection. this ore uses the pitch automobile spiral pit line development. craft part including perforation equipment shaping and quantity computation, power shovel equipment's shaping and quantity computation, automobile quantity computation and shaping, bulldozer shaping and quantity computation, supporting facility's shaping and quantity computation and so on. The demolition method is the choice and the dose computation, the transportation switches cars the way is the choice, arranges the folk recipe method choice and the row of earth computation. key word: Opencut mining development craft excavation progress schedule
