XXXXXXXXXXXXXXX MINING
Mine code no: XXXXXXX
Risk Assessmentin order to determinethe need forProximity Detection Deviceon TMM’s at XXXXXXXXXX Mining
INTRODUCTION:
XXXXXXX is a private company and the registered holder of a Mining Rightnumber XXXXXX. It is an open pit operation mining diamonds by means of excavation by TMMs and transporting to screening and washing plants where the dense diamond bearing material is separated from gravel.
The xxxxxxxxxxxxxx has a Mining Right on the portion of the property in extent approximately xxxxxxx hectares chosen by and allocated to the mine. Portion xxxx and xxx of the farm xxxxxx, District xxxxxxx
Overburden is stripped away in order to reveal the Diamond bearing gravel. The gravel is mined via open pit excavation with a maximum depth of 6 - 12 meters. Diamond bearing gravel is, where necessary,loosened (fragmented) by means of Excavator or ripping. The loosened material is then loaded onto TMM(s)andeither transported directly to the primary tipping bin for processing or the material is stored in a stockpile for later processing at the plant. From the stockpile a Front End Loader then feeds the primary bin for further processing in the plant.
The processing plant consists of a primary receiving bin, vibrating and/or barrel screen(s), conveyor belt system(s) that feedsrotary, slurry pan(s) where the dense concentrate is separated from the lighter material. Lighter material is then used in the rehabilitation process. The dense material is then further processed for final diamond recovery.

METHOD:
XXXXXX MINING took into consideration the risk of pedestrians being injured as a result of collision between TMM’s as well as the risk of pedestrian(s) and TMM incidents on the mine.
Legislation Applicable – Mine Health and Safety Act, 1996 (Act No 29 of 1996) Chapter 8 with the exception of regulation 8.10.1.2 and 8.10.2.1(b)
DEFINITIONS:
TMMMeans any self-propelled mobile machine that is used for the purpose of performing mining, transport or associated operations at a mine but, excludes rail bound equipment.
Yellow TMMMeans any equipment used to load, haul, dump, excavate, rip or move overburden or ore bearing material and includes Dozer, Front end loader, TLB, ADT, Mobile Screen/Crusher
LDV Means light delivery vehicle.
C1 Means a vehicle (TMM) with tare weight between 3 500kg and 16 000kg;mini-buses,buses, LDVand goods vehicles with GVM between 3 500kg and 16 000kg. A trailer with GVM of 750kg or less may be attached.
Haul Road Means a road used exclusively by TMM’s and specifically designated C1 vehicles.
THE RISK ASSESSMENT INCLUDED THE FOLLOWING:
- Number of TMM’s in operation on the mine:
In order to limit possible congestion, only the essential required TMM's are to operate on the mine. Unauthorised TMM will be stopped when not required to operate. One way haul traffic route(s)areused on the mine. (See: traffic management plan)
- The number of TMMs operating at the same time on the mine:
Only two ADTs operate on the mine at the same time. One way circular route established on the mine. There is no possibility of congestion on any road, loading or tipping area.
2 ADT
2 FEL
1 Excavator – pit loading
1 Excavator – screen loading
- The areas that TMM’s operate on the mine:
Only authorised TMM's will operate in demarcated areas. No other TMM is allowed on the haul road(s).
- The probability of the TMM’s coming into contact with each other:
Routes on the mine were altered to ensure that TMM travelling at speed in opposite directions cannotcome into contact with each other when operating on the haul roads. Berm walls separate individual haul roads. Speed limits are limited at maximum 40km/h for all TMMs travelling on haul roads. One way haul roads have been established and maintained on the mine. Where dual roads are built for C1 TMMs the minimum road width shall be 3x the width of an LDV or a minimum width of 6 metres. This will enable safe passing with ample space between LDV’s.The turn-around time for the ADT route is approximately 15 minutes. The distance from the pit to the tipping area is approximately 300m.
- Alternate routes travelled on the mine by the other TMM’s / Vehicles:
Alternative routes are constructed for other TMM’s i.e. LDV, personnel transporters, visitors etc.and are indicated on the attached traffic management plan. Livery and high visibility Buggy whips must be fitted to C1 TMM’s that are allowed on haul roads or load/tipping areas.
- Possibility of changing the routes travelled on the mine:
Due to the nature of the type of alluvial mining done it might be necessary to move mining pits and therefore mining roads will change but then it would necessitate the traffic management plan to be changed and updated by the Manager.
- Operators relation to TMM’s while being loaded:
Compliant TMM's with OEM certified cabs are in use, operators are trained to remain in the cab while loading takes place. No person made be on foot in any pit area while operation is commencing.
- Placement of “safe parking” areas:
Should there be more than one ADT approaching the loading or tipping zone then the incoming TMM will park at the safe waiting area (indicated by a sign reading: safe parking area) and only approach when safe to do so. One way haulage route will be established on the mine for TMM’s.
- Access roads to and from the pit and plant:
A berm wall will be erected between traffic with opposing directional haul roads to ensure TMM's do not come in contact with each other or other vehicle/TMM e.g. LDV's, delivery vehicles, etc. Rotating or flashing orange beacon lights must be fitted to any TMM using the haul road. In addition any LDV required moving into production areas, in and around the plant or pit areas must have an approved buggy whip / flag fitted.
- Unique pedestrian travel routes:
Pedestrian travel routes will be limited to plant and admin areas, pedestrians do not commute on TMM haul roads. All workers are trained on this procedure. Pedestrian only travel routes asspecifically indicated by road signs.
- TMM’s running out of control:
Operators are trained not to speed or overload TMM's. Speed and traffic control signs are in place. All TMM's are serviced as per the OEM specification, brake tests done daily before commencement of the shift on all TMM’s as well as the LDV that is required to enter a decline or pit. Berm walls have been erected.
- Overturning of TMM’s:
Yellow TMM's with OEM certified cabs in use. On mine speed limit is enforced (max 40 km/h). Operators remain in cabs while loading. TMMs that have OEM seating and safety belt fitted to the TMM are, under certain circumstances,allowed to have passengers. LDV’s that are allowed into the pit must be fitted with ROPs.
- Objects falling on operators/passengers:
Although TMM are fitted with FOPS, the relatively shallow open cast pits are such that FOPS is not required on the mine. No employees are allowed on foot in the pits without the permission of the supervisor or manager.
- Person falling out or being ejected from the TMM:
All TMM's are fitted with the safety belts, operators are trained to use them and management enforces the use thereof.
- Maintenance of TMM’s:
All TMM's are maintained as per the OEM specification and requirements.
16.Training:
All workers and TMM operators are trained on this procedure as well ashazard identification and risk assessment. Toolbox talks are held that re-enforce this procedure.
