The Quarry

The South-West Sectors

Sector 3 Excatavion side Will be extended over the next production cylces Bench hights m with an over all slope Angle of 45° and a face angle of 23° Bench width is approx. 30 m to enable save working space for heavy machinery Rocktraps secure man and machinery from potential rockfall – sufficient size

Sector 3 Hazards Dominant Joint intersect with blasting pattern Secondary jointing runs 35° to it – This can cause smal scale wedges Water runoff can increase possible rockfall
