open pit mining

The open-pit mining of a surface-oxidized copper ore was carried out which did not consider the influence of underground mining at all.

Open-pit mining to be transferred into underground mining is an issue many large or middle-sized mines have to face early or late.

Through the ecology repair measure, it may slow down the open-pit mining effectively to the ecological environment influence availably.

Open pit mining production scheduling is of guidance significance to the mine construction and balanced production.

Main Produces: Continuous open pit mining systems, Stockyard equipment, Ports and bulk terminals equipment, Conveyor transportation systems.

Open-pit mining follows the same sequence of operations as underground mining: drilling, blasting, and loading and removing waste and ore.

Mining transport system is one of the most important production links in open-pit mining process.

This law has guidance to the slope excavation engineering practice in open-pit mining transferring.

The disciplines include mining, open-pit mining, coal processing, mine MEP, and machinery.

The technology is very useful for exploiting gentle-inclined thin bauxite body as well as for open-pit mining of iron ore.

Relative to the waste rock dump of underground mining, open-pit mining needs a larger one.

Pit is the end of open pit mining stope space formed by the border.

Research on the safety and stability of slope in open-pit mining is very significant to safety production of open mines.

The open pit mining method, belong to sag with different slope surface.

With the yearly increase of the depth of open-pit mining, the water infiltration of borehole can not be ignored.

Open-pit mining was a big business in Minnesota until the mid-1970s.
