process. However, most of the narrow reef mines where trackless mechanized mining was introduced in the early 1980s have reverted to conventional mining. In the wider reefs mechanized mining is the option of choice; unfortunately most of the gold and platinum mines have very narrow reefs that are not suited to off the shelf equipment.

the narrow reef miner. The machine was designed and manufactured and surface tests were completed in October 2001. The prototype ARM 1100 was then commissioned at MOXHAM, A hard rock narrow reef mining machineARM 1100. International Platinum Conference Platinum Adding Value,The South African Institute of Mining
The mining method proposed by a consultant to Anglo Platinum was based on the current trackless mining method practised by Union Section. The trackless mining method is better described as a trackless development and transport method. Reef strike drives were installed approximately 40 metres apart on dip using trackless equipment. Reef was
ULP mining below 400 m utilizing the narrowreef mechanized mining layout has been shown to create significantly more value from both a financial and an operational perspective, due to the extraction ratios that can be achieved using these methods coupled with the overall efficiencies (gt;4000 m2 production per month) of the XLP/ULP equipment.

Mining severity Advances in technology in mining have resulted in general improvements in mining conditions, especially in the fields of ventilation, mechanized mining equipment and drilling and blasting techniques. Unfortunately, many of the operating mines are designed around less efficient technologies
Industry: Underground mining Customer: One of the worlds largest mining companies (South African market) Challenges: Impossibility to fully mechanize the mining cycle in the narrow reef mining equipment which is a very labour intensive, unsafe and inefficient process Customers requirements: Development of fully electrically powered and remotely controlled equipment
A FRAMEWORK FOR THE INTRODUCTION OF MECHANIZED MINING 117 Introduction This paper focuses on the issues pertaining to the introduction of mechanization in an underground narrow reef hard rock mine typified by, but not solely restricted to, platinum mining in South Africa. In the context of this paper, mechanization refers to any machine, process or
Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth''s surface. It is found mostly all over the world.
underground mining equipment CLEAN, ENERGY SAVING TECHNOLOGY All HPE underground machines and equipment operate on high pressure water, which not only is a powerful energy source but is clean, nonpolluting and noncontaminating, but also solve and overcome health and safety issues as well as environmental challenges.

While most of the gold and platinum mines in South Africa have very narrow reefs (lt;1 m) that are not conducive to off the shelf copper or coal mining equipment. This implies that new
