COMMUNICATION “Communication is the exchange of information
and ideas from one person to another”
TELECOMMUNICATIONTelecommunications refers to the exchange
of information by electronic and electrical means over a significant distance either by cable or in the form of electromagnetic waves.
TELE COMMUNICATION TECHNIQUES
WITH WIRE WIRELESS
PRESENT COMMUNICATION SYSTEM IN
SHYAMSUNDARPUR COLLIERY
WITH WIRE TELEPHONE
DRAWBACK OF WIRE TELEPHONE
Telephones located at Shyam Sundarpur Colliery are in strategic points at 2no. Pit, and 3no. Pit. This system has the inherent limitation as Wires are to be laid to the specific points and they cannot be extended.
RECOMENDATION
WIRELESS COMMUNICATION-
1. PED CAPLAMP RECEIVER2. VOIP PHONE
PED CAPLAMP RECEIVER
PED CAPLAMP RECEIVER
(Approved by DGMS, approval no. 629 of 2011manufactured by Mine Site Technologies Pty. Ltd, Australia)
FEATURES- Intrinsically safe declared by DGMS, Dhanbad.One way TTE (inside the mine) system operating at frequency range of 1 KHz for
digital text messaging.Use of ultra-low frequency (ULF) signals enables PED to transmit directly through
rock strata Personal Receiver is integrated with a miner’s cap lamp. This can be the ultra-light
weight lithium ion battery pack, known as the Integrated Communications Cap Lamp (ICCL) , or receiver versions are available to retrofit to some existing Cap lamp batteries (such as Koehler- Wheat, Oldham, Northern Lights and MSA). On receipt of a message, the cap lamp flashes, a buzzer sounds, and the 32 character text message is illuminated on a liquid crystal display. The PED R receivers always indicate that they and the transmission system are operating.

VOIP PHONE
VOIP PHONE
FEATURES-Intrinsically safe declared by DGMS, Dhanbad.It is a portable handsetallows users to make and receive VoIP phone calls from any area
of the mine covered by the wireless network includes mine specific functionality including Push To Talk (PTT), emergency alarmsbattery life designed to last an entire shiftCapable for both voice calls and text messagingis IEEE 802.11b/g (Wi-Fi) compliant
TECHNICAL
SPECIFICATION
CONCLUSIONTraditional mine communication system (Normal Telephone) should effectively replaced by the personal emergency device (PED) and VOIP Phone Handset for better safety to the miner working in underground mines proposed in the paper. This paper gives detailed system of wireless communication which is used in several mines along the world including USA, CANADA, SOUTH AFRICA, AUSTRALIA, and in many more. This paper specifies in detail the systems of intrinsically safe wireless communication, approved by DGMS which includes PED cap lamp receivers and VOIP Phone Handset for safety and security of underground mines. This system is reliable, faithful, uninterrupted, economical and user friendly. A larger area and more depth inside hazardous underground mines are now can be covered and potential accidents can be controlled effectively. Now proper monitoring and conversation is possible between the workers and the ground staff which can help to take appropriate actions more rapidly and smartly. This system also can be easily extended and it will improve scalability of underground environment and extend accurate position of miners.
