MINING NEWS

Mining operations experience difficulties

with their vehicles on a daily basis

due to the rigid landscape, operational

inefficiency and lack of safety within the

workplace. The new 40.00 R 57 and 53/80

R 63 Michelin XDR3 tyres have been

designed to improve these factors.

The new Michelin XDR3 is said to re-

spond to the needs of mine operators by

incorporating three key innovations, which

together increase tyre life by a minimum

of 10% compared with its predecessor, the

Michelin XDR 2.

Compared with its predecessor, the tyres’

new tread pattern offers multiple benefits.

It offers better endurance due to improved

heat dissipation capabilities – 8°C cooler

in the tread area. A greater volume of tread

rubber is in contact with the ground, which

improves wear and ensures better load dis-

tribution throughout the contact patch due to

a lower contact pressure. Interlocking shoul-

der blocks resist excessive movement during

cornering and further reduce tyre wear.

With four innovative rubber compounds –

the MB4, MB, MC4, MC – the exclusive new

mixing process ensures a more uniform com-

position of rubber compounds and a greater

level of carbon black dispersion that increas-

es wear resistance. Each unique compound

offers specific performance characteristics

adapted to site conditions and usage, from

high wear resistance to high thermal capac-

ity for speed.

The high-strength corrosion isolating steel

cables used in the tyre’s casing are 10%

stronger than in the previous XDR2 and are

encapsulated in rubber to prevent the spread

of corrosion within the casing, which extends

the life of the tyre. The 40.00 R 57 Michelin

XDR3 is available from September 2016,

while the 53/80 R 63 will roll into the market

in January 2017.

MBE Minerals is expanding its service

centre in Kathu, South Africa. Officially

launched in the second quarter of 2015,

the facility supports the company’s large

installed base of equipment in the Northern

Cape Province.

Johannes Kottmann, managing director

of MBE Minerals, explains the importance

of providing support on customers’

doorsteps. “It is imperative that we can

provide technical support and backup

services to customers in this region from a

local facility and the decision to expand our

existing service centre will see a sizeable

investment by the company.”

MBE Minerals is a leading supplier of

iron ore and coal beneficiation technology,

and is focussed on providing the greater

aftermarket support. Kottmann says that

this approach enables the company to

meet customer-specific requirements. He

says that mines need OEM suppliers that

are committed to work with them to ensure

the optimum efficiency of equipment.

“It is not sufficient to just provide qual-

ity OEM equipment that is engineered to

be fit-for-purpose, it is also essential that

technical support is readily available to en-

sure optimum uptime and productivity for

the mine,” he says.

The MBE Minerals Service Centre, which

is under the management of Rudi van

Deventer, will be doubled in size to allow

for the reconditioning and assembly of

bucket chains and jigging panels. The fully

equipped workshop will accommodate the

inspection, repair and assembly of various

other components as well. A comprehensive

spare parts stockholding matches with the

company’s equipment footprint, allowing

customers ready access without the need to

wait for these to be shipped from Gauteng.

When it comes to breathalysers, there are

many misconceptions that exist (and persist)

about what these tests can and can’t do that

have led to the belief that it is possible to

beat the breathalyser, so says Rhys Evans,

MD of ALCO-Safe.

“This is something often attempted at

roadblocks where there is police presence

to monitor drunk drivers and it has even

been attempted where substance or

alcohol testing is implemented randomly

in a manufacturing, mining or construction

environments,” says Evans. “Such tricks

have evolved into an urban legend with

most people able to pass on a story of how a

friend or acquaintance fooled a breathalyser

test, but these tricks are nothing but myths.”

In short, there is no way to beat a

breathalyser test, unless the test subject has

not been drinking. Despite this, companies

and law enforcement agencies are having

to test more often, illustrating the fact

that employees and citizens are unfamiliar

and misinformed about the extent of

alcohol testing, whether for recreational or

professional purposes, which means it’s time

to demystify these urban legends, says Evans.

Designed to test for blood alcohol content

(BAC), breathalysers are used in industries

and scenarios where intoxication is

hazardous to health and life. South African

law has two levels for permissible BAC

percentages – the professional driver limit

is 0,10 mg/l. For obvious reasons, alcohol

consumption is banned by the OSH Act and

is predominantly enforced in the mining, civil

engineering, construction, manufacturing,

transportation and other industries with a

zero tolerance approach, given the serious

ramifications of operating dangerous

machinery under the influence. Testing for

alcohol is mandatory in certain industries,

and this is done using a breathalyser before

entering the workplace.

While there are a number of different

types of breathalysers, the good ones gen-

erally work the same, and they are all de-

signed to be used by an operator.

“It’s important to know upfront that if the

operator is using the test device correctly

by not handing it to the person to test him-

self, and if the device used is a good-quali-

ty breathalyser, there is no way to cheat it.

However, in order to ensure that the device

delivers accurate readings, it is important

to calibrate the breathalyser,” says Evans.

“Good breathalysers use something called

an electro-chemical fuel cell, which is the

heart of the instrument detecting alcohol.

This can go up in sensitivity or drift down in

sensitivity.”
