Shaft Access. Figure 1 Underground shaft layout. Shaft access utilizes a skip and hoisting system in order to transport workers and materials through a vertical passage loed near the orebody. Generally this system is best suited for deeper mines that will require higher production rates. A general rule of thumb states that a mine that has ...
What is open pit mining . Open pit mines are those mining operations that take place on the surface, unlike the underground mines. This is possible when the reservoir sprouts on the surface or at a very small depth. It began to be realized in the middle of the XVI century and it is used all over the world.
Mining engineers then oversee the construction process and manage the technical aspects of production once the pit is open for business. Eventually, once a mine has been exhausted of its resources, or acceptable safety levels have been compromised, a mining engineer will be in charge of closing the mine and filling in the mine shafts.
