Abstract

Highwall mining, an extension to open cut mining, commonly use auger and continuous highwall mining system. Highwall stability is the overriding concern in highwall mining. Rock properties and structural geology of rock are the vital parameters for designing highwall mining. The basic equations for computing web and barrier pillar strength, applied stress and stability factors are dealt in the paper. W/H ratio should also be maintained for the stability of highwall. Diligent monitoring of displacement rates is imperative to evaluate the stability of the highwalls and, in turn, safety of men, material and machineries. Several land based, airborne and satellite based techniques of highwall movement monitoring have been discussed in this paper. Preventive measures should be adopted for safe mining of highwall.
