Communication Types

Conclusion

Outline


4/20


UndergroundMining

Activity, occupation, and industry concerned with the extraction ofminerals under the surface of earth.

Efficiency and Productivity

Cons: Inmine vehicle accidents.

Roof falls, fire, explosions, toxic gases, and floods.

Emergency response for underground mines is much more difficult.



5/20


Communication, Why?


Remote Monitoring and Control,

Information Flow,

To Rescue the Employees when Accident occurs, Emergency Preparedness,

Quick Response.

Locating the Trapped Miners.

Communication Requirements: Throughout each working section

Continuous coverage along escape ways

Device Requirements: Back-up power supply capacity

Survivability requirements

Tracking precision

Mine coverage

Requirements:


7/20University of Management and Technology

Wired communication systems,

Radio communication systems,

Carrier current communication systems,

Hybrid systems,

Other systems.

Communication Types:



Better Coverage

Higher Data Rate

Types Magneto (Crank Ringer) Phones

Soundpowered Phones

Paging Phones

Dial-&-Page Phones

Disadvantages

Wired Communication System:



Magneto (Crank Ringer) Phones

The basic principle of this type of system is to generate acurrent that is strong enough to make bells of otherphones ring in a private line manner.

Soundpowered Phones

Voice of speaker is converted to electrical signal andtransferred.

Short Range

Wired Communication types


10/20


Paging Phones

Each individual device has its own internal battery

Being Reliable

Easy to install and maintain

Prevents simultaneous transmission

Dial-&-Page Phones Paging only cannot locate a person.

High voltage insulation with multiple-pair cables.

Multiple functions

Complex infrastructures

Goal

To operate seamlessly

To cover the entire working area Pros :

Reduce Confusion

Decrease the chance of wrong Information Being Communicated

Decrease Buzz

Increase Confidence In Decision

Improves the Likelihood Of Success

Radio Comm. System:


12/20


TTE communications, Earth as common medium

Low frequency usage to location miner

In

mine communications, Communicating inside galleries under the surface

Wireless networks, Wireless local area network

Coverage range can be up to 1500ft

Ultrawide band (UWB) systems. High data rate with low power consumption

very high time resolution

high accuracy

Radio Communication types


13/20


CCCS use of fact

Radio waves are fed into any underground wire orcable, they are distributed throughout its length.

Most Dependable com. on the carrier frequency

Mechanical strength and better insulation

Easy Maintenance

Types;

Trolley Carrier Phone

Hoist Rope Phone

CarrierCurrentCom...


14/20


Trolley Carrier Phone

Receiver and transmitter are connected to the trolley wirethrough a coupler capacitor, blocking high voltage levels.

High mechanical strength Hoist Rope Phone

Pushtotalk, Releasetolisten design.

Used for different levels

Easy to implement Removes language barrier

Combination of Wireless and wired com. properties

Types

Leaky Feeder System Allows radio transmissions to both, from the cable and to enter the

cable

Increases the propagation range,

Fiber Backbone Networks

Utilize fiber backbone networks to provide wireless

communication Radio Frequency Identification (RFID) Systems

Communication between RFID tags and fixed transceivers.

Location precision

Hybrid Systems


16/20


Advantages

Shock Detector

Visual Indication Types

Seismic Systems

Stench Systems

Visual Pager Systems Optical Communication Systems

Other Systems


17/20


Seismic Systems

Shock vibrations can travel through Earth

Stench Systems

Use of a clearly distinguishable odor

Visual Pager Systems

Used along with pager phones

Preferable in noisy environment

Optical Communication Systems

Use of bright or high-density light

other systems (Cont)


18/20


Rich but highly risky business that require propercommunication.

No single communication method has been developed yet

to solve the issues.

Wireless communication offers solutions to some of thefundamental challenges.

SDR was introduced initially. But it cant address at longer

distances.

Modifications o SDR leads to CR (cognitive radio) thatobserve their environment and react upon the changes.

Critical Thinking Is A

Crucial Key To Success.

Youre the Main Reason To Work

Safe . Sa fe ty is More Precious

Than Gold !!!
