1 INTRODUCTION

1.1 Background

Seriti Coal (Pty) Ltd (Seriti Coal) obtained the remaining Metsimaholo reserves as part of a purchase

agreement that saw Seriti Coal take ownership of the Anglo American Coal mines supplying coal to

Eskom. This report evaluates the impact of the proposed development on the surrounding road

network as part of a first high level evaluation.

1.2 Study Area Description

The Metsimaholo prospecting right covers an area of approximately 34 377,63 ha in extent. The

Metsimaholo colliery is straddled by the town Refengkgotso to the north-eastern corner of the

project site, and to the east by Deneysville town located 3km from the proposed site as shown below.

The proposed study area is situated within the Metsimaholo Local Municipality of the Fezile Dabi

District Municipality in the Free State Province of South Africa.

Figure 1: Site Locality


Final ITS 4073


1.3 Mining Operations

The proposed Metsimaholo mine will be an independent mine producing thermal coal from one

operational decline shaft. The run of mine production profile is approximately 3 million tonnes per

annum (Mtpa), depleting in 2054. The project is planned to commence in 2023 with the pre-

construction and construction phase.

Mine establishment and access development are scheduled to commence in quarter 3 of 2023. The

project is planned to commence initial production in 2025. The operational phase of the mine will

run for 24 hours a day seven days a week excluding holidays.

The potential life of mine is anticipated to be 30 years delivering an average of 2.8 to 3.0 million

tonnes per annum of coal to steady state production. The total saleable product is estimated at

approximately 80 million tons over the life of mine with an average calorific value of 19 megajoules

per kilogram.

Based on the above tonnages, the mine will start producing approximately 900 000 tonnes a year in

2025 and slowly ramp up to full production of 3.0 million tonnes per annum in 2031. This implies the

following in terms of haulage trucks:

At the start of mine 4 trucks an hour will be transporting coal from the mine.

The number will increase to 12 trucks an hour once the mine reaches full production.

Coal will be transported on a 7 days a week, 24 hours cycle excluding public holidays.

The market at this stage is inland with possible clients based east of mine and west of mine

(Grootvlei power station and Sasolburg).

1.4 Study Objectives

The purpose of this report is to provide a Traffic Impact Statement that will:

Show the potential impact of the development on the surrounding road network,

Discuss the potential access requirements and /or restrictions, and

Propose a high level Traffic Management Plan

2 ANALYSIS

2.1 Trip Generation

As per the information supplied, the following trips will be expected during the operational phase of

the mine, starting in 2025.

Final ITS 4073


The number of peak hour trucks was arrived at by calculating the total number of trucks per day

average and then assuming that peak hour consists of 10% of the total daily traffic. This assumption

is based on other mines with similar operations.

Total number of vehicles 85 48 37 123 67 56

2.2 Existing Traffic Count Data

No existing count data was found for the area. It is recommended that an updated detail traffic study

be done closer to the construction phase. Traffic counts will then be required on the roads near the

access points.

2.3 Trip Distribution and Assignment

The trucks will supply the local market with coal and therefore the trips will be distributed on the

following main roads:


Final ITS 4073


R57

R82

R549, and

R716

Assuming an even distribution among the roads, the average total additional traffic per direction

would be approximately 32 vehicles which would further break down to 16 vehicles per direction per

day.

2.4 Traffic Impact

The impact of this low number of vehicles per intersection would be low. The main impact will be at

the access points to the mine and mitigating measures are discussed later in this report.

2.5 Access & Weighbridge Operations

Access to the mine will in all likelihood be provided from the surrounding provincial routes. Access

roads must comply with the following provincial standards and requirements:

• Minimum access spacing of not less than 600m.

• The access spacing measured from the provincial route to the nearest access road of not less

than 100m.

• The stopping sight distance standards as prescribed by the road authority should be used. The

minimum stopping sight distance for a design speed of 80 km/h at a 0% gradient should be a

minimum of 120 meters.

• The minimum gap acceptance sight distance for a design speed of 80km/h for a single unit

and trailer is 305 meters.

It is important to note that adequate storage space should be provided to avoid truck queues forming

on the provincial routes.

Should the mine consider utilising weighbridges then it would be recommended to use a weigh-in

area and a weigh-out area with two separate access roads where possible to improve circulation.

Based on previous studies it is recommended to provide at least 2 in and 2 out weighbridges to

accommodate a maximum peak hour volume of approximately 50 vehicles per hour. This implies a

vehicle per weighbridge every 2.4 minutes.

The position of the security gates before and after the weighbridges must be carefully considered to

allow for adequate stacking space.


Final ITS 4073


3 MITIGATING MEASURES

3.1 Public Transport

Adequate drop-off and turnaround space must be provided for the Bus and Taxi operations at the

mine. Shelters should be provided where necessary.

3.2 Non-Motorised Transport

Non-motorised transport movements are minimal in the area. However adequate paving should be

provided at the bus stop locations at the mine.

3.3 Access Upgrades

The access points to the mine will require upgrading to provide for safe right and left turning

movements as slow moving trucks will pose a safety risk for fast moving traffic.

Access roads must be constructed to accommodate at least E80’s (coal trucks) based on the truck

volumes.

3.4 Network Upgrades

No immediate network upgrades are envisaged, but some turning lanes might be required at the

nearest intersections to the access points. These will have to be investigated as soon as the exact

access point locations are known.

Road signage should be provided to indicate slow moving vehicles and heavy vehicles turning. The

governing speed should be clearly indicated at the intersection of the access road to the main

network.


Final ITS 4073


4 TRAFFIC MANAGEMENT PLAN GUIDELINES

It is important to minimise the impact of the development generated traffic during the construction

and operational phases. As such, the following mitigating measures are proposed as outlined in the

table below. The measure proposed below constitutes a high-level Traffic Management Plan. A

detailed traffic Management Plan that incorporates the guidelines set out in this section of the report

should be developed by each contractor.

Generation of Dust

Cover materials with tarpaulins where possible,

alternatively wet sand and/or provide other

means of dust suppression. Treatment of dirt /

sand roads near communities would be

advisable

Risk of vehicle collision Indicate areas where heavy vehicles will be

expected with adequate signage

Risk of pedestrian accidents

Clearly indicate pedestrian crossings.

Educate drivers on potential areas of high

pedestrian and cyclist activity.

Educate community on dangers of construction

vehicles new to their area.

Degradation of Public Roads

The deterioration over time must be monitored

and a maintenance plan must be negotiated

with the Provincial Authority.

Traffic Delay None required

Generation of (Coal) Dust Cover materials with tarpaulins where possible.

Risk of vehicle collision

None required other than that prescribed by the

local authority for this class of road already

prescribed and implemented.

Risk of pedestrian accidents

None required other than that prescribed by the

local authority for this class of road already

prescribed and implemented.

5 CONCLUSION AND RECOMMENDATION

The impact of the proposed development on the surrounding road network is low. Upgrades will be required

to the access points along the main roads. Additional upgrades at key intersections might be required to

provide safe turning movements. The additional upgrades can be finalised once the access points are finalised.
