DESIGN OF MONITORING SYSTEM FOR COAL MINE/ OPEN MINE SAFETY BASED ON WIRELESS SENSOR NETWORK
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.
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.
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.
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:
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.
coal mining personnel and vehicle safety monitoring system.
Information conveying systems.
Substation monitoring system.
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
