| In this report accident statistics are linked to the
hazards identified on the mines and the major risks to the employees as a result of these
hazards. Some of the more significant measures in progress to deal with these risks are
set out, as well as the major health findings identified through the medical surveillance
programme. The occupational environment
Averaged over the year, the company was responsible for the
health and safety of 94 000 employees in service, including 9 600 contractors (i.e. 10 per
cent). Because of the disposal of a number of shafts during the year, employee numbers
were reduced accordingly and 82 449 were recorded as 'at work' at year-end.
The great majority of employees work in underground mining operations, where the
mining of narrow reefs takes place at depths between 1 000 and 4 000 metres below surface.
High rock temperatures require the control of the thermal environment by means of
ventilation and refrigeration. To this end, 14 600 kilograms of fresh air are circulated
per second and 695 megawatts of refrigeration employed to provide conditions conducive to
health, safety and productivity. The mining method requires tunnelling and stoping of
excavations using explosives to generate ore, which is then transported in haulages to
vertical shafts for hoisting to surface. These activities can create hazardous conditions
which require continual management of the working environment and specific engineering
controls.
The Navachab and Sadiola open-pit operations are generally of much lower risk. At
Navachab, ore and waste rock is mined by conventional surface drilling and blasting
methods. The rock is then taken by truck to the ore and waste piles. At Sadiola, the
nature of the ground is such that it can be loaded directly by excavator onto trucks for
subsequent transport to the plant.

Members of the AngloGold Executive Committee
visited Kopanang mine - one of several such visits to operations during 1998.
Hazard identification
The nature of the various operations gives rise to the
following significant hazard profile:
Safety hazards Health hazards
 |
Seismicity and falls of ground |
 |
Dust |
 |
Transport, machinery and equipment |
 |
Noise |
 |
Flooding/mud rushes |
 |
Heat |
 |
Fires |
 |
Ionising radiation |
 |
Explosives and explosions |
 |
Gases |
 |
Damage to shaft |
Of these, seismicity, damage to a shaft and the use of
explosives, are the most critical safety risks. The most serious risks to health result
from dust and noise, caused by mining operations and machinery respectively.
Risk management strategy
The promulgation of the Mine Health and Safety Act in January
1997 placed certain obligations on South African mines to carry out risk assessments and
to put into place structures by which health and safety would be managed effectively.
AngloGold worked throughout 1997 and 1998 to further improve effective risk management
through programmes of risk assessment and employee involvement.
To deal with identified hazards, a strategy for the limitation and effective
management of health and safety risks has been in place at all of the underground mines
for the past year. It incorporates a structured site-specific approach to the assessment
of risks, as well as the training of personnel in hazard identification and risk
assessment. It also includes the controlled use of new technology, and administrative
structures for the control and auditing of the management systems.
