The EMCA System is the best Life Saving Technology ever to be used in the Mining Industry.
The EMCA (Electronic Monitoring Cable Anchor) device was developed in South Africa by Sandbox Mining, specifically to find a way of accurately measuring pressures and tensions in rock anchors. It does not rely on people as a primary warning system - rather it becomes the primary warning system by actively monitoring tension in every anchor it is fitted to. It is set to an upper and lower limit which will warn the rock engineers of any movements in the hanging walls or sidewalls (focused on pillar pressure monitoring). It records a history of the specific anchor's tension and thus can give indications of what is happening in the rock.

Safety in Mines through Innovation.
We feel it is of great importance to send this email regarding a newly developed and unique way of accurately, continuously monitoring and measuring (once installed in stope faces and development ends) the real time behaviour (pressures and tensions) in rock anchors and temporary support systems (Camlok Support). The main focus of this technology is to assist the Mining Industry Leadership with a method for the prevention of Fall of Ground incidents / accidents.
Mines have embarked on a Mines Health and Safety drive, focused on reducing FOG (Fall of Ground) incidents / accidents through a FOG programme. However, this programme still relies on the human element to identify any potential hazards in time.

The Electronic Monitoring Cable Anchor (EMCA) or Closure Monitoring Device (CMD) fitted with an ELI (Electronic Load Indicator) does not rely on the human element as a primary warning solution - instead it becomes the primary real time warning solution by actively monitoring and measuring tension with any movements in the hanging walls, sidewalls and/or pillars it is installed on.
The EMCA is set to an upper and lower threshold which informs the Mine Management Team via SMS and email of any change of condition. The device also records a history of specific support tension data in a user database and can indicate the condition in the rock, requiring immediate action. The system also has a user interface which can be configured to log in and view real time or historical data.

This system utilises more than one method of communication (Leaky feeder, Fibre Optic or Wireless). The system communicates the real time information to the surface control room and also gives visual indications by means of a tricolour LED mounted on the device. We believe this system is a life saver and will prove itself to be a reliable safety management system, capable providing effective early warning of life threatening situations.
