Under The Earth

Introduction Why Underground? Reserve is deep, uneconomical to remove the overburden Underground: All kinds of design you can imagine Transport (people, waste rock and ore) through: Decline Shaft Decline and Shaft

Shaft and Decline

Development Create accesses and other openings (water sump, power station, shop etc.) in waste rock. Cycle/Round – Drilling – Blasting – Mucking – Ground Support Basic Terminology – Rib- Side Wall – Sill- Floor – Back- Roof Overhead – Face – Active Working/Advancing Surface

Drilling

Blasting Load drill holes with explosives and…… ….BOOM!!

Mucking

Ground Support: Bolts & Mesh

Ground Support: Bolts Prevent wedge failure Hold mesh (wire)

Patterns Several types of bolts used ranging 5 to 12 feet in length Spacing and bolting pattern dependent upon ground conditions and life span of drift

® ® weellxS ® weel l x S Different Patterns For 100% Coverage

Ground Support: Shotcrete Form a support arch Fill in voids between rocks and bond them together Stop rock weathering

Ground Support: Shotcrete
