For increasing the coal productivity and

transportation capacity, and environment

improvement, recently, under the coordination

between Quang Hanh Coal Company and VIMS AT, the

installation of the conveyor system for coal

transportation from the ground of +20 level to the

Central coal separation area has been carried out

replacing the transport form of using trucks with low

capacity and high operational and maintenance cost.

The paper also introduces the main technical features

of the conveyor system.
