Abstract:
Lack of geomechanical parameters for the digging force in underwater mining conditions was noticed during analyzing the available technical documentation at preparatory phase for the revitalization of the vessel bucket wheel excavator "Kovin I" vital parts. This fact has caused the need for the implementation of relevant research program that will determine the water pressure effect on the coal mining process. The research program included certain geomechanical laboratory tests which are adapted to the specific conditions and needs of underwater coal mining. The program had included coal laboratory testing of the linear and surface digging force in underwater conditions at different hydrostatic pressures of the water column. Intention of this laboratory testing program was to simulate underwater coal mining conditions at different depths of the excavation – digging according to the "in situ" principle.

Key words:
digging force,underwater mining,coal

Thematic field:
System engineering, risk management and modern trends
