Coal is an important fossil fuel used for the generation of electricity and other industrial activities. Basic menace in
mining process is due to frequently occurring underground accidents. The mining industries are dynamic in nature because of
continuously changing environment of underground mines, hence accidents occur in the process of mining and thousands of
casualties occur every year. The accidents can occur because of electrical failure, entrapment, exploding vessels under
pressure, fire, falling of roof, handling material, etc. The topographical constraints make the situation worse. The interactive
communication between different types of systems becomes difficult. The equipment interconnection and power supply are
more susceptible that may damage due to accidents hence the entire system becomes weak and inactive. It becomes difficult to
track the location of the mine workers during roof fall accidents as the mines get dumped with huge pile of rocks and dust.
Tracking the workers, dead or alive becomes critical for the mine authorities. This study was carried out with an intention to
design a device which will enable tracking the location of the mine worker along with pulse rate detection. By wearing this
device, it is possible to continuously monitor the location and the vital signs of the human body in case of accidents. The device
will also sense the pulse rate and help in providing immediate medical help to the mine worker in case of fainting or drop of
blood pressure due scarcity of oxygen. This prototype design is such that it is easily wearable and does not hamper activities of
mine worker. The designed prototype will continuously monitor pulse rate as well as location of the mine worker and send the
information to the base station. In case of any emergency, the last location of the mine worker can be easily tracked and rescue
can be provided effectively. The comparative study of the existing system and the designed prototype has been carried out.
