The higher productivity for open pit mining equipment also lowers costs. The necessary underground equipment for maintaining productivity is more expensive on a unit basis capacity than corresponding open pit equipment. Furthermore, the large production scale and share number of open pit mines have provided the opportunity for manufacturing open pit equipment in large numbers, thus reducing ...
The potentially hazardous nature of open pit mining requires the appliion of sound geotechnical engineering practice to mine design and general operating procedures, to allow safe and economic mining of any commodity within any rock mass *. The intent of this guideline is to provide examples of good geotechnical engineering practice and to assist mining operators in achieving compliance ...
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. In order to be carried out, the excavation (using machinery or explosives) of the lands ...
