本文详细介绍目前南非地下矿机械化掘进与回采用凿岩台车的实际费用与效率指标。这些资料是从深的金矿井到浅的贱金属矿井的各种硬岩开采与掘进作业中收集到的。这项调查包括老式风动凿岩台车和新式电动液压凿岩台车,但不包括井筒钻机和新近为薄矿脉研制的回采用凿岩台车。发表这份材料的目的,是向那些要决定是否采用机械化凿岩台车的人们提供指导;如果决定采用的话,还可指导他们确定要采用的凿岩台车型式和台数。
This article describes in detail the actual cost and efficiency of rock drilling rigs used in underground mine mechanization in South Africa. These data were collected from various hard rock mining and driving operations from deep gold mines to shallow base metal mines. The survey included both old-fashioned pneumatic rock drilling rigs and new electro-hydraulic rock drilling rigs, but excludes wellbore rigs and newly recovered rock drilling trolleys developed for the thin veins. The purpose of this publication is to provide guidance to those who decide whether or not to use mechanized rock drilling rigs and, if so, to guide them in determining the type and number of rock drilling vehicles to be used.
