Project Summary

Mining assumes essential part in the vast majority of the creating nations to meet the vitality requests. Nowadays mining industry is facing numerous problems primarily the safety of the miners. The condition of the underground mines in particular is naturally exceptional. Emissions of harmful gases such as methane and carbon monoxide are caused by dependence on mines. The combination of these gases beyond the safety threshold level causes hazardous events in the mines and is harmful for the life of the miner. Subsequently a persistent checking of such parameters is vital. Smart helmets have been developed to identify hazards in the mining industry. The four hazards considered while developing a smart helmet are air quality, temperature, helmet removal and collision (miners collides with an object). The CO, SO2, NO2 and methane are considered hazardous gases and concentration levels of these beyond the threshold values are considered as the first hazardous event, air quality is checked using air quality sensors. Then the minor who remove the helmet off their head is considered the second dangerous incident. An IR sensor was developed to test whether the minor helmet was worn. High temperature is considered as third hazardous event because miners cannot work at high temperatures and the temperature is measured using a temperature sensor. The fourth accident was defined as an incident in which a miner was struck on the head with an object with a force of more than 1000 on the HIC (Head Injury Standard). The accelerometer is used to measure head acceleration and the HIC is calculated in the software. This data will be processed in the processing unit and the processing unit/microcontroller notify in hazardous situation.

Project Objectives

Monitoring

To monitor the parameters like the saturation of hazardous gases like carbon monoxide, nitrogen dioxide, and methane, temperature, the pressure of the air, and moisture level detection. Communication

Monitored data will transmit toward the helmet of another miner as well as the control room with the help of a ZIGBEE transceiver. We can use ZigbeeCC2500 for fast communication in underground mines.

Rescue

At whatever point the values received from sensors exceeds the threshold (Ideal for working in underground mines) values of temperature, carbon monoxide, nitrogen dioxide, methane, air pressure, and moisture level, or a miner removes his helmet from the head or any external force collides his helmet the Zigbee module at helmet side sends a flag to the other helmets as well as a controlling unit. A buzzer, LED lights, and voice module will also indicate the hazardous situation. 

Protection: 

Due to this remote correspondence framework, delegates are prepared in advance against the display underground structure. So the protection team will take quick action and ensure the safety of the miners. Therefore the risk of miscarriage due to environmental variables of underground mines is reduced.

Project Implementation Method

Sensors are placed on helmets which will sense the different parameters in underground mines and send this signal to the signal modification circuit.

The signal modification circuit will modify (Conversion from analog to digital or amplification) the Signals and send them to the processing unit.

The processing unit processes the values of different parameters and compares the values with the threshold values and also displays them on LCD. If the values will be greater than the threshold, the processing unit sends the signal to the buzzer and ZIGBEE module.

ZIGBEE sends the signal to the ZIGBEE transceiver.

Signal will be received at supervisors’ end in a hazardous situation and the Protection team will take safety steps to save the lives of miners.

Benefits of the Project

Can be widely used in Mining Industry for the safety of the miners.

Can be used in underground working sites for the safety of workers (other than Mining).

Can be used to detect harmful gases like CO, CH4, and NO2 in the mines.

Can be used at noisy workplaces for faster communication through ZIGBEE.

Can be used in the Safety monitoring of the environment.

Can be used in any weather conditions.
