for the Modern Miner using Shotcrete
"The most significant barrier to the use of synthetic fibre has been the impact on the pumping systems. A submersible dewatering pump like JetGuard, which readily reduces the problems of synthetic fibre damaging pump impellers, is going to have a positive effect on production."

The Adoption of Shotcrete in Australian Underground Mining
Over two decades, the use of Shotcrete in underground mining has grown rapidly in Australia due to its effectiveness in tunnel stabilisation. As the use of Shotcrete has increased, the industry has learned and improved. This article reviews the history of Shotcrete use in underground mines in Australia. It explores the early drivers, the challenges,…
A Submersible Pump Designed To Deal With Shotcrete Fibre
Shotcrete Has Changed The Rules for Underground Mining
Most of the world's underground mines use Shotcrete to reinforce the walls of new tunnels. The use of fast-drying concrete makes the tunnels more stable, delivering safety and other benefits.
Shotcrete used in underground mining is frequently reinforced with small fibre to strengthen it.
The Shotcrete fibres can subsequently fall from the walls and mix with waste water.
The use of Shotcrete fibre has delivered major benefits for underground mining companies.
And it has also delivered some big, unintended consequences for dewatering operations.
How Shotcrete Fibre Can Cause Pumps to Fail
This picture shows a submersible pump where the impeller has failed due to Shotcrete fibre.
As water is pumped out of the mine, Shotcrete fibre is drawn into dewatering pumps and clogs them up.
Dewatering pump breakdown caused by Shotcrete delays mining production all over the world every day.
The Impact of Shotcrete Fibre on Mining Operations
When dewatering pumps are critical infrastructure, an entire mine can be forced to shut down because of dewatering pump failure driven by Shotcrete fibre.
The pump shown here was designed before Shotcrete was even invented. It wasn't designed for today's conditions.
The pump itself might have been located in a part of the mine that is difficult to access. This can make it hard to detect when a problem has occurred, and there are often substantial costs and risks associated with retrieving and repairing the pump to restore dewatering operations.
The Cost of Pump Failure
For many underground miners, Shotcrete fiber represents a major cause of pump failure and production delay.
And what is is the real cost of pump failure for a mining operation?
A multi-million dollar mining operation can be brought to a standstill because of one dewatering pump failure. The cost of the failure is not just measured by the cost of the replacement pump, but by the total lost production as well.
But production delays like this could be avoided if dewatering pumps are selected that have been designed for modern mining conditions.
The choice of a tougher pump can also reduce workplace hazards and boost efficiency.
JetGuard® is Protected
JetGuard has a defence-in-depth design to protect the pump from Shotcrete fibre.
Blocking Fibre From Getting Into the Pump
JetGuard is designed to block fibre from entering the pump.
JetGuard's patented design uses a hydraulic curtain to spray a curtain of water at the base of the pump.
In addition, JetGuard uses a bottom-mounted suction strainer, in contrast to older pump designs that use side-mounted suction strainers.
A lot of Shotcrete fibres float on the surface of a body of water. The combination of the hydraulic curtain and bottom-mounted suction strainer blocks many of the surface fibres that may otherwise get into the internal workings of the pump.
JetGuard® is Tough
JetGuard® has been built to be tough enough to withstand Shotcrete fibre for longer.
Managing Fibre That Gets Into the Pump
While JetGuard protects the pump from fibre, a reduced amount of fibre will still enter the pump.
JetGuard uses tough steel for internal components, avoiding lower-cost polyurethane and other plastic-based materials. Fibre chews up plastic, while it has far less impact on steel.
The JetGuard design incorporates a specially designed internal cutter plate. Any fibre that does get into the pump is chopped into small pieces to minimise impact. This reduces wear and tear on the pump, and allows for a clearer flow.
JetGuard® is Productive
JetGuard® is a new breed of submersible pump designed to keep you mining
Less Breakdowns More Production
What is the true cost when a submersible dewatering pump fails and causes mining operations to stop?
Think about it ... a multi-million dollar mining operation brought to a standstill because a single dewatering pump fails! Increasingly, the root cause of that pump failure is Shotcrete fibre.
Production delays like this can be avoided if the dewatering pumps you use are tough enough to handle modern mining conditions.
Tougher pumps can also help reduce workplace hazards and boost your efficiency.
It is true that the upfront cost of a JetGuard® pump is slightly more than its low-cost competitors. But when measured on total cost of ownership, JetGuard truly shines.
