A Brief Introduction to the Types of Surface Mining Methods

These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method in North America. ? Previous Post Next Post ?

Surface mining is the most common mining method worldwide, and open pit mining accounts for more than 60% of all surface output. Haulage costs account for as much as 60% of the total operating cost for these types of mines, so it is desirable to maintain an efficient haulage system. As the size of the haulage fleet being used increases, shovel
