Due to the impacts on ecological environment, production safety and economic benefits of large open-pit water deposits, there is no longer a single drainage method within pit that can be used meet need for further deep mining. Therefore, curtain grouting technology proposed use in prevention control mine water. The flow equation slurry vertical fissures under influence self-weight stress was de...

Cutoff grade is a grade used to assign a destination label to a parcel of material. The optimal cutoff grades depend on all the salient technological features of mining, such as the capacity of extraction and of milling, the geometry and geology of the orebody, and the optimal grade of concentrate to send to the smelter. The main objective of each optimization of mining operation is to maximize...

The stability of mine slopes is an important factor influencing the orderly production mines and safety people’s lives property. can be effectively determined by means three-dimensional simulation analysis. Some 3D analysis methods are based on 2D analysis, still essentially methods, whereas this digital uses a true method. This method reflect overall slope in more realistic way, at same time, ...

The paper substantiates and proposes a method for selecting mechanization tools crushing conveyor complexes as part of cyclic-flow technology in open-pit mining. proposed methodology justifies the types means complex used at Yoshlik-1 quarry JSC “Almalyk mining metallurgical combine”. task developing optimal technological parameters equipment conditions is formulated. Optimal were selected usin...
