摘要

Excavation performance is a term used in underground construction to describe the influence of several parameters on the cutting rate of mining machinery. The main factors affecting the excavation performances are:The geology (rock and rock mass mechanical properties and conditions).The process (in terms of operation, maintenance, logistics).The methodology (the type of machine, tools and ground support chosen).
