Our Mission
• The Leadership and Staff of Sandbox Mining, in collaboration with our Associates, pledge that we will strive to develop and introduce new and innovative equipment with appropriate technology to assist the South African mining industry in particular and the International mining industry in general.

Why are we here? • Currently limited technology to
measure the behaviour of tendons
and cable anchors once installed.
• Potentially dangerous working
conditions, associated with current
tendon installations, have been
identified.
• Potential additional ways to minimise
loss of production have been
identified.
• Rehabilitation of collapsed
excavations is costly.
• Potentially harmful Workforce
incidents.

Electronic Monitoring Cable Anchor Device
(EMCA) SA Patent Application No. 2010/05562
Depending on the tension deviation from
the set point on the anchor, LED’s
colours change as follows:
Correct tension: safe working conditions
Danger: Evacuation – Increase in
tension.
Warning: Rock movement – loss in
tension, inspection needed
Note: Personalise warning via cap lamp
cable (Optional)

Robust construction test. Amandelbult Dishaba & Impala 2A Mine
After the blast the units were opened and examined, it was
established that the units were not damaged. (refer to SRK report) 7
After:
Before:
1st Blast – units installed 500 mm from the face before the blast.
2nd Blast – units were 2m from the working face.

Considerations
• What will it
cost ?
Modelling the
costs – will be
based on volume?
• When will the
ECMA be
available?
The EMCA is
available with
stock on hand.
EMCA’s
Relay Units
Accumulator
Server UPS

Financial Implications
Financial arrangements can be made to suit individual mines/operations.
e.g. 1) CAPEX on hardware.
2) Leasing of monitoring equipment and software.

This is a positive indication
that closure took place.
Temporary support on the
Face is very important
