DESIGN OF MONITORING SYSTEM FOR COAL MINE/ OPEN MINE SAFETY BASED ON WIRELESS SENSOR NETWORK
OBJECTIVE:

 The foremost critical task for coal mine is of keeping track of miners spread out across a large mining areas.
 Many mines use a radio system to track miners, but when a collapse occurs, the base stations connected by a thin wire often are rendered useless.
 In this project and implimentation to overcome the demerits of radio system we used wireless technology for tracking the miners.
 A small RF transmitter module is equipped to each person entering a mine.
 The transceivers communicate with base stations through zigbee module inorder to look after the miners. In addition we also include sensors to intimate the base station & miners when some atmosphere changes occur.
 Mine operators are now able to monitor the real-time locations of each miner to better pinpoint their locations in the event of an emergency.
MODEL REPRESENTATION:
Existing system:

 Miners accident often happened.
 weak safety and legal consciousness.
 Efficiency of rescue was low, and the effect was worse.
 Improper information communication between the ground personnel and the underground.
DEMERITS:
 MANUAL MONITORING-loss of employees due to time delay. Production was reduced.
 WIRED MONITORING- needs large cabling and it is more expensive.
 RF MONITORING-long distance is not applicable for monitoring.
Proposed System:
 Established an underground safety monitoring system with integrality.
 Effective alert system when dangers happen.
 Enhance search and rescue efficiency.
 Manage the harm-gas concentration.
 Access control for the works passing in and out laneway.
 Enhance the mining production management level and the work safety level of the mine.
HARDWARE & SOFTWARE COMPONENTS:
 Microcontroller
 Temperature sensor
 Gas sensor
 Pressure sensor
 RF module
 Zigbee module
MERITS:
 High safety system and performance.
 Effective alert system.
 Reducing accidents and saving life.
 Easiest way to monitor and control system.
 Efficiency of rescue was high.
Applications:
 coal mining personnel and vehicle safety monitoring system.
 Information conveying systems.
 Substation monitoring system.
Conclusion:
 Advent of RFID technology in the coal mining management, and established an underground safety monitoring system with integrality, real-time and flexibility, which could automatically alarm when dangers happened and enhanced the search and rescue efficiency
