COMMUNICATION
VIDEO SURVEILLANCE
Underground mining surveillance assumes a basic job of ensuring the well being and security of man and machine. Presently, sensors and simple cameras are being utilized for ecological condition observing only. The framework is completely computerized including the camera sensor which uses IP based MJPEG video spilling to screen. It shows the natural condition and helps take clear decisions in perspective on live video feed and provide emergency support.
Reason for video surveillance:
The video monitoring equipment is for the most part simple camera, having good sign quality and also helps in monitoring in long transmissions.
Mining industry uses CCTV simple cameras as a remote video watching game plan and uses ground control staff to screen and record the underground work site prosperity.
The proposed system can be used as a piece of an underground mine to ensure prosperity and security of the miners and other noteworthy equipment. Next will be to screen the natural condition and take clear decisions in perspective on live video continue and give emergency organizations.
WIRELESS VOICE COMMUNICATION :
In underground (U/G) mines communication is a crying need both from well being and efficiency perspective. The need to keep pace with the market and lifestyle of the miners and, demands more reliable communication methods.
Wired communication fails in circumstances where availability is must for example in case of underground mines fire flare-up, rooftop fall, power or battery fails, blasts and so forth. This is the reason; wireless communication has a key job in underground mines.
Tracking of Vehicle, Personnel’s and Equipment's :
Whether you need to locate a vehicle or a worker instantly, require real-time visibility of a specific zone on your site or demand a rapid way for electronic mustering, our system is designed to improve the performance of today's construction sites.
Our system pairs labels with thin line RFID readers that help characterize each zone on site and establishes an advanced framework for even an incredibly unsafe underground mine.
TRAFFIC SIGNALING SYSTEM
One of the most difficult tasks the mine business needs to manage is the control, protection and movement of its assets and workers.
It is important to stress that our traffic signaling system is protected against any hardware or software fails that might occur and can cause the normal connection software-traffic lights to be lost.
This is achieved by giving local intelligence to the system, i.e. the local hardware units (gateways) that are connected to the traffic lights are set with basic traffic rules that will be automatically applied in case any such fail occurs, thus guaranteeing traffic safety at all times.
Leaky Feeder
A leaky feeder communication system consists of a coaxial cable run along tunnels which emits and receives radio waves, functioning as an extended antenna. The cable is "leaky" in that it has gaps or slots in its outer conductor to allow the radio signal to leak into or out of the cable along its entire length

AUTOMATION
PLC (programmable logic controller):
PLC a programmable logic controller (PLC) is an industrial digital computer which has been adapted for the control of Mining industrial application, manufacturing processes, such as assembly lines, or robotic devices, or any activity that requires high reliability control and ease of programming and process fault diagnosis.
It is the preferred option for increasing output, with safety in gassy underground mines by way of switching off power supply when concentration of flammable gases exceeds permissible limit and simultaneously raising alarm to help save miner’s valuable lives and assets mines property.
Oorja on move provide services in various projects like:
PLC automation for shaft signaling system.
End to End traceability of aluminum billets and cathodes
Getting critical parameters over SMS & emails.
DCS:(distributed control system)
A distributed control system (DCS) is a computerized control system for a process or plant usually with a large number of control loops, in which autonomous controllers are distributed throughout the system, the use of smart devices and field buses makes DCS to be prominent in large and complex industrial processes as compared to the former centralized control system.
Oorja on move provides its services in the following areas:
Underground Mine Development & Production using Latest Mining Technologies
open cast mining.
Surface Mining.
Shaft Sinking.
Decline Development.
Increasing productivity, safety and cost effectiveness of the industrial processes.
SCADA(supervisory control and data acquisition):
SCADA is a central control system which consists of controllers network interfaces, input/output, communication equipment and software. The systems are used to monitor and control the equipment in the industrial process which includes mining, manufacturing, production, development and fabrication. It takes the reading of the meters and checks the status of sensors at regular intervals thereby requiring minimal human interference.
Oorja on move provides its services in the following areas:
Monitoring of different parameters like RTD diagnostic data, LVDT diagnostic data, Shaft position, Alarm status etc. in mines.
Trend analysis
Provision for trends check and report generation of needed parameter.
GAS MONITORING SYSTEM :
Environmental gas monitors are capable of measuring ambient gas concentrations and includes a variety of features that makes them powerful and easy to use. This process is done using Leaky feeder cable system.
Gas monitoring includes:
Carbon Monoxide
Nitrogen Dioxide
Nitric Oxide
Methane
Oxygen
Hydrogen Sulfide
Sulfur Dioxide
Hydrogen

Mine Ventilation
A complete solution related to mine ventilation for Ex- different range of fans, blowers and dampers.Whether you need a solution for an existing ventilation plan or a new plan for type of fans best suited to you , Oorja on move can help keep you up and running. Our team can assist you in selecting the right solution for your mine.
Air conditioning unit
As the depth of excavation increases, the heat has detrimental effects to miners’ health and performance. This is brought about by expanding temperature of rock mass, aggregated water and activity of electrical equipment/ignition motors. So as to guarantee protected and safe working conditions, the air conditioning systems for underground mines must be installed. This decreases the temperature and humidity of air and working conditions are extensively improved. Our team has a wide range of solutions and we have customized solutions depending upon the situation.
The following is a complete set of cooperating devices referred to as the group or central air-conditioning system:
Refrigerating units that produce ice water
Air coolers that remove heat from heading
Re-coolers that are designed to collect heat of condensation from the units
Electrical/hydraulic or pneumatic fans for providing forced air circulation in the coolers. Option: air movers.
Electrical devices (power supply, control system, monitoring system, air quality control system).
The complete set of these cooperating devices is referred to as the group or central air-conditioning system.
