Encardio Rite offers a variety of underground mine monitoring and open-pit monitoring instruments for the measurement of deformations, groundwater, strain, stress, and load. These monitoring sensors have proven to be extremely reliable and can work efficiently with high performance under harsh conditions. It provides accurate and important quantitative data regarding the behaviour of the surrounding rock/ground, performance of the ground support systems, safety and stability of the underground mining work, and the excavation progress.
Geotechnical Instruments have a monumental role to play in the continual productivity and safety of mine, whether underground or on the surface. The geological formations are highly influenced and impacted by mining, and therefore, these formations also have an effect on mining. When it comes to underground mining words, the most significant threat to safety and operations is from the ground movement as it can result in rock falls, tunnel collapses, and other catastrophes. In the case of the open-pit, it becomes crucial to keep an eye on the slope stability, ground movement, soil behaviour, ground movements, and surrounding structures.
The online web-based underground mine monitoring service provided by Encardio Rite is well-equipped with automatic alerts and warning systems for the early detection of ground failures and other mishaps. The use of advanced technologies like automatic 3D deformation monitoring using ATS, laser scanning and aerial survey using drones makes for an infallible monitoring plan.
Underground mine monitoring and risk assessment have the following benefits:
Improve Safety – It helps to maintain safe operational systems and procedures and guard personnel, material, nearby structures, communities, and the environment. If there is a potentially unstable ground, it provides timely alarms.
Economical – Geotechnical Instrument helps in the optimization of mine operations. For example, increasing steepness of slopes to minimize waste removal and increase recovery of ore helps to keep an eye on the slope movement and the surrounding ground.
Control & Remedy – Having a mine monitoring plan assists to provide an alert on any expected failure zones, develop and design appropriate remedial action plans, and safely evacuate the area without any life loss.
Confirm Designs – Evaluating the performance of ground support system, stability of underground mining operations, and slope designs.
Assessing Impact of Natural Events – Produce accurate information and details of the impact of events such as earthquakes, excessive rainfall, etc to help minimize the risk associated.
Regulation compliance – To conform to the current and future standards & regulations for safety.
Future Understanding – Preserving a history of information helps to identify different rock/soil/slope behaviours over a long period of monitoring.

The Encardio Rite Solutions for online monitoring of mines include:
The advances and progress in technology have enabled geotechnical instrumentation, geodetic survey, and data transmissions systems to monitor the mining work performance from any remote location. Data Loggers and total stations pick up the reading from the installed sensors at selected intervals. If any of the reading is above the predetermined trigger values, an alarm or an SMS is sent to the authorities. All the data collected by the sensors are transmitted to a remote data management software, at a central server or cloud, where they are processed, evaluated, and presented. The same becomes accessible to the concerned authorities, at their desk or mobile devices through the world wide web.
