Coal Mine Detection using Embedded System using ARM7 .
· Coal Mine Detection using Embedded System using ARM7 TDMI LPC2148 ABSTRACT : Using embedded system this paper monitors the presence of human beings in the coal mines. The method utilizes PIR Sensors, Microcontroller, MIWI technology, Zigbee to realize the operational parameter and intelligent monitored management of entire mining area.
SURFACE GEOPHYSICAL METHODS FOR DETECTION OF .
Mine voids in coal mines are usually encountered as resistivity lows because of the presence of acidic mine water. Other Methods, such as magnetics and ground penetrating radar have been used for detecting subsurface cavities, but can be subject to precision, interference, or depth limitations which restrict their use in mining appliions.
