Mining of raw materials is a process that consists of several stages. In openpit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive
Openpit mining is a type of surface mining used to extract coal, gold, and other minerals. It creates immense water and air pollution, disfigures landscapes, and destroys habitats.

Analyst Mike Kozak from Cantor Fitzgerald agreed. "KSM is in a class of its own as the world’s only standalone developmentstage mining project capable of producing +1 MMoz Au annually for decades from openpit operations only," he wrote last year. Kozak has rated Seabridge a Buy with a CA$43.50 target. It was CA$15.47 on Thursday
The openpit mining cycle includes drilling ore and waste rock, loading drill holes with explosives, blasting, ore loading and hauling to stockpiles for processing, waste rock loading and hauling to the waste rock storage pile. Occasionally, drilling and blasting ore is not required and can simply be removed by what is known as free digging.

The model could be exactly solved by commercial MIP optimiser (e.g., ILOGCPLEX) for smallsize instances in a reasonable time. The proposed approach has been applied to a case study based on the data collected from an iron ore mine site in Australian, for the purpose of maximising the productivity of shortterm openpit mine
Open pit mining method is one of the surface mining methods that has a traditional coneshaped excavation and is usually employed to exploit a nearsurface, nonselective and lowgrade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main

There are two types of benches in each open pit mine: working benches and safety (catch) benches. Working Benches. Working benches are where unit operations (drilling, blasting, loading, and hauling) are performed. Working benches are wider than safety benches to provide enough room for the mining equipment to perform their tasks. Safety (Catch
