Minecorp specialises in mine specifications on all vehicles - servicing of fleet vehicles, safety cells, exploration, underground vehicles, tray backs, game viewers, trailers, casual services and upgrades. Here is some information on the isolation and lockout products we provide..

Isolators are available in assorted styles and configurations for different requirements, from single isolators (battery or starter) to dual isolators (battery and starter).

These also include single isolators without jump start facilities, single isolators with jump start facilities, double isolators without jump start facilities and double isolators with jump start facilities.


Single pole isolators can be used for battery or starter isolation.

Single isolators can be used for battery or starter isolation with jump start facility.

Double isolator with jump start facility.



Single pole isolators are used to break a single pole on the vehicle. This isolator can be used as a starter isolator or a battery isolator.


Double pole isolators

Double pole isolators are used to completely isolate the vehicle by breaking both negative and positive poles.


Battery isolation

Battery isolation is used to completely lockout a vehicle using a master lock for maintenance and repairs as well as shift change and grounding of an unsafe vehicle.

Starter isolation

Starter isolation is used to lock out the starter motor on a vehicle. This type of lockout still gives the service technician, shift change driver and/or supervisor the ability to do a full electronics check/test without the risk of anyone being able to accidentally start the vehicle.


The jump start receptacle is used in conjunction with the correct compatible jumper cable fittings and:

  • Eliminates connecting the jumper cables accidentally to the incorrect poles on the vehicles
  • Prevents damage to either vehicles electrical systems
  • Prevents fire hazards caused by shorting out the batteries
  • Prevents voltage spikes when the second vehicle starts


These isolators can be used on a variety of different vehicles including:

  • Light delivery vehicles
  • Trucks
  • Earth moving equipment
  • Drill rigs
  • Generator





If it has a battery, Minecorp SA can isolate it!

Solids results: Managing risk with drilling fluids

Solids control technology is being utilised more and more, helping drilling contractors to differentiate themselves by delivering additional health, safety and environmental benefits.

Drilling fluids are composed of a wide variety of chemicals. While the majority of Drilling Fluid Products are designed to minimise their impact on the environment, there are still those which can pose risks to Health and Safety or which may be harmful to the fauna and flora or contaminate waterways or land areas. Vigilance is required not only during the direct handling of drilling fluids and chemicals but also as part of their wider use in the drilling process.

Significant volumes of drilling mud can be generated from drilling operations, some of which may not be suitable for reuse and may need to be transported and dumped. Replacement drill fluid may require fresh make up water to be transported to site. If sumps are being used, they need to be dug and managed. These processes all require close management to ensure they can be completed safely for people and the environment and have the ability to affect project scope, budget and timeframes.

The use of sumps and the large volumes of drilling fluid chemicals and water that goes along with it, represents a prime risk in any drilling operation.

What are the risks of drilling fluid sumps?

Traditionally sumps have been used to store large quantities of drilling fluid after use. Regardless of being above ground or in ground, drilling fluid sumps have several pitfalls:

  • Digging, construction, re-mediation and removal of these sumps may prolong operations and add unnecessary costs
  • The slurry may be affected by weather, such as freezing cold or warm, evaporative temperatures, making the drilling fluid less suitable for reuse
  • Fluid leaking into the surrounding environment or waterways is still a risk
  • Screening may be required to ensure local wildlife and staff do not ingest fluid, fall into sumps or drown
  • If the slurry has a high water content, this may put stress on sumps with limited capacity making it  more expensive and potentially more complex for disposal
  • Site footprint is increased
  • Excessive water usage

The sump method is complicated, disposal and outsourcing environmental specialists for remediation is still required. Sometimes this may not be an option, especially for smaller contractors, remote projects, scope of budget or local regulations.

What is solids control technology?

Solids control technology is being utilised more and more, helping drilling contractors to differentiate themselves by delivering additional health, safety and environmental benefits.

The award-winning AMC SOLIDS REMOVAL UNIT™ is the ultimate companion for drillers, enabling cost-effective, minimal impact drilling, even in the most restricted locations. Available in several configurations, these innovative closed-loop systems eliminate the use of sumps and maintain drilling fluid at optimal performance, delivering ROP improvements as well as drastic water, mud and waste reductions and more.

The AMC SURFACE SRU™ works by circulating drilling fluid directly from the drill collar to be processed by the shaker and centrifuge, where drill solids are separated from the mud slurry and discharged via a waste chute. The unit’s high-speed decanting centrifuge is specifically adapted for diamond drilling, operating up to 3,000rpm, to remove solids to less than 5 microns and keep drilling fluid in excellent rheological condition. After being processed, cleaned drilling fluids flow into a tank for return to the drill rig for re-use. The drilling fluid is contained throughout this whole process.

Why use solids control technology?

Without processing the mud slurry directly from the hole, solid cuttings may cause wear and tear on drill bits, wireline and other components, typically reducing the life of the equipment, and lowering the ROP while increasing maintenance and replacement costs. Sand content can also be an issue, with its abrasive effects on pumps. Reduced bit life, bit changes, maintenance and replacement of equipment can have drastic effects on operational time and costs. The AMC SRU™ creates drier cuttings waste with a water ratio of 1:1, no runoff from cuttings occurs and the water left is likely to evaporate in the right conditions. The volume of cuttings for disposal is also significantly less, and has proven to reduce waste volumes up to 96%. 

The AMC SRU™ can significantly reduce water and mud consumption and their associated costs. The closed-loop system recycles drilling fluid, shrinking mud consumption by up to 75%, by returning clean fluid, with optimal drilling fluid properties to the drill hole.

“The SRU™ has substantially lowered our water content; this both reduces the volume of material transported from the rig and reduces the potential of suspended solids to run off in freshet surface waters.” - Dave Cox, Site Geologist - Aurora Geoscience

Clean, non-abrasive mud can reduce incidents of stuck pipe and damaged drill components. Due to reduced rod trips, pulling and reaming, the AMC SRU™ is able to reduce the level of operating labour required on site and risk of injury.  The AMC SRU™ creates a drier, safer work environment, containing and reducing the volume of water and mud on site, reducing slip and trip hazards caused by mud on roads and run ways, as well as reducing drive time for support vehicles including vac and water trucks and associated driving risks.

“The AMC Surface SRU™ provided considerable cost savings as excavation, drainage and rehabilitation were not required, and the unit returned a lot of the additives to drill circulation instead of being lost as sludge.” Dr Bryan Smith – Consultant Geologist.

Following the Reduce, Reuse, Recycle philosophy, you can both better manage your risks to health safety and environment as well as operational costs. Recycle your drilling fluids and reuse them and reduce the amount of drilling fluid chemicals used in the process.

Solids control technology is proving to be an essential part of drilling fluid risk reduction for operations. The AMC SRU™ closed-loop system has received several accolades for its innovation contribution to the drilling industry, eliminating the need to manage sumps, and providing a solution to reduce overall risk and enable drilling in remote or environmentally sensitive areas.

Master Drilling taps into Table Mountain Group rocks

Drill Safe

Screen Shot 2017-10-18 at 3.32.36 PM.png

By W.C Olivier

Master Drilling, the local and international technology driven company, in November 2017 embarked on a challenge to drill horizontal diamond core boreholes into the Table Mountain Group quarzitic rocks, of the Hottentots-Holland Mountains near Kylemore, in the Western Cape. The project was initiated by the Stellenbosch Municipality in consultation with the groundwater consulting company GEOSS This is the first attempt in South Africa drilling horizontal diamond core boreholes into the side of a mountain cliff face, giving the opportunity to tap into “underlying” aquifers. These horizontal boreholes form part of Master Drilling’s extensive regional projects which aim to urgently boost the water supply for the Western Cape region by tapping aquifers with sufficient water yields.

It is expected that these boreholes will unlock large groundwater aquifers which will aid the efforts to relieve the immediate water needs of Stellenbosch and later, the larger City of Cape Town municipalities.

The Table Mountain drilling is particularly challenging due to the tough drilling conditions posed by the hard and fractured Table Mountain quartzites. Master Drilling made a few quick adaptions to the drilling conditions and as a result the first 200mx122mm diameter borehole progressed well and was recently completed. Several additional horizontal core holes will be drilled at this site, with the possibility of drilling in other locations in the near future.

A second portion of the current project involves percussion drilling in the immediate vicinity where GEOSS are targeting the confined Peninsula Formation of the Table Mountain Group.  The borehole depths have reached a maximum of 400m thus far. Some of the boreholes completed to date have delivered considerable yields with the greatest yield achieved so far, being in excess of 30l/s.

Master Drilling is confident it will continue to achieve success in the region and is committed to greatly expanding its services to help assist with the future aquifer drilling programs in the region.

The drilling of these horizontal boreholes has once again affirmed Master Drilling’s ability to overcome challenging drilling problems and prove itself as a one-stop drilling solutions provider.


Diamond Core cutting blades

Drill Safe

sponsor Geo Explore Store.png


Along with the core cutter, this can be a dangerous subject and is of concern to most safety officers. Geo-Explore Store has developed some standard or optional features, as below, to maximise the safety on our range of core cutting blades.

  • All segments are laser welded to the steel disc (blank), this provides a stronger bond and as a result the blades can actually be used to cut dry (not ideal but historically the segments would fail if the blade overheated).
  • High decibel noise pollution has always been an issue, and although we recommend ear protection is used around core cutters, our blades are available with “silent centres”. This reduces the noise levels significantly and allows for a more comfortable cutting environment for the operator.
  • Segment matrix has been optimised to ensure the correct matrix/diamond mix is used to cut various rock types, this ensures the blades are less likely to polish or become "blunt” and keep cutting freely so the operator does not try and over exert the core cutter resulting in fatigue or machine failure.

Please contact us should you have any questions or need guidance regarding the ideal solution for your project.


Drill Safe

REFLEXT Logo Tagline.jpg

Using the REFLEX CORE REMOVAL TOOL™ in the extraction process means the drill crew no longer need to strike the core with hammers or other hard objects in order to release it from the core lifter case. Protecting the ends of the core sample from impact damage will result in the ability to join the ends together with greater confidence in the accuracy of the logging process. Use of the REFLEX CORE REMOVAL TOOL™ protects the core orientation markings significantly.
