such as plants, workshops, slimes dams and waste dumps. Mining costs The mining functions at Letseng are carried out by contractors accounting for more than 70% of the total mining cost. Unit mining costs for ore are higher than those of waste owing to a tighter blast pattern for ore, resulting in higher powder factors and higher drilled metres.
Health Practice in the South African Mining Industry. Fortunately I had the privilege to launch this book at the CSIR the same year and the audience enquired as to when a handbook on Occupational Safety in the South African Mining Industry would be published. Today, five years later, I am proud to state that this has been achieved.
→ unplanned movement of mobile plant. In 2002, MDG 15 was revised to apply to mobile and transportable plant in all mines (other than underground coal mines). The number of notifiable incidents associated with mobile and transportable plant remains significant. Key areas that need to be addressed in mobile and transportable plant include:

of high-grade ore and can be acquired at a cost of $10 per ton of ore (cost of mining ore at site). A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce 99.9% pure gold bullion from the ore. The results of the feasibility study show that the ore can be processed by agitation

For some years after these pioneer machines were developed, requirements remained very simple. All mining and quarrying, whether underground or open-pit, was done by hand as tonnages generally were small, and product specifications simple and liberal. Even the largest commercial crushed stone-plants were small, consisting of one crusher,

Batch crushing plants The history of mobile crushing plants started with roadside crushing and screening operations and more particularly gravel quarries located near the road works. The requirements were small and typically throughputs of 10 to 50 t/h were usual. These plants used small jaw crushers, screens and slewing stackers for stockpiling.

Longwall Mining The second underground coal mining system is longwall mining. Originally developed in Europe, longwall mining is now also popular in the United States because of the greater safety and efficiency it affords. In this method, a rotating shear on the min- ing machine (figure 10) shaves from blocks or panels
