Drilling rate prediction of an open pit mine using the rock
2015 1 1 and RDi values, drilling rate can be predicted for all the mine zones. The predicted drilling rate for each zone of Gole Gohar Sirjan open pit mine is shown on Fig. 7. It can be seen that the predicted drilling rate in the most zones varies between 0.25 and 0.8 m/min where only in two zones the drilling rate exceeds 1 m/min. Get Price

Open Pit Mining
2021 1 7 Open pit mines are used when deposits of commercially useful ore or rocks are found near the surface. To create an open pit mine, the miners must determine the location of the ore. This is done through drilling of probe holes in the ground, then plotting each hole location on a map. Sophisticated geophysical logging services can assist in this

Mining
Open pit mine. Most iron ore mining operations use the 'open pit' method, where miners drill into the rock and blast the ore bearing material loose with explosives. Huge excavators are then used to gather the loosened ore. To mine metallurgical coal, which will later be turned into coke, it's usually necessary to sink vertical mine shafts Get Price
