Safemet – To Redefine Mine Safety

A smart helmet is to be developed that can detect hazardous events in mining industries, tunnel works, etc. These areas are subjected to many hazardous situations. Let's considered the three main types of hazard that usually occur in mines such as poor air quality, helmet removal and collision with objects. The first type of hazard, i.e., poor air quality refers to the increase in concentration of hazardous gases such as CO, SO2, NO2 and particulate matter inside the coal mines which is dangerous for the mine workers. In order to handle this situation sensors are provided in the outer surface of the helmet which will detect the presence of any hazardous gases. Sensors are also provided to measure the mine temperature and humidity. If any hazardous situation is detected, an alert message will be sent to the base station. The second hazardous event is the situation in which the miners remove the helmet off their head. In order to tackle this situation, a switch is given in the strap of the helmet such that the switch is activated when the helmet is clipped. The third type of hazard is collision of the miner's head with any objects or sudden fall of the miner. This can be detected with the help of a vibration sensor. When a vibration of comparatively higher magnitude is detected, the base station (BS) is notified about the situation. There is a unique identification (UID) tag given for each helmet. In case of an emergency situation, the unique tag is also sent to the base station so that it is easy to identify which mine worker is affected or is in danger.
