The mining industry is very concerned about industrial safety. For workers to be safe and productive, communication and healthcare are essential. To monitor and react to potential dangers, reliable communication is essential, while medical personal protective equipment and examinations are crucial. The mining industry has to improve safety measures because the existing safety systems have flaws. To minimize dangers and safeguard workers, the mining industry uses safety systems like ventilation, emergency response plans, and gas monitoring. Fresh air is provided via ventilation, dangerous gasses are detected by gas monitoring, and accidents are reduced by emergency action procedures. These systems have drawbacks, including the inability to detect all gasses, insufficient airflow, and a limited ability to reduce accidents. Therefore, these systems need to be improved. By enhancing communication and utilizing the IoT (Internet of Things) to monitor air quality, toxicity, and workers’ vital signs, our solution increases safety in the mining industry. Real-time monitoring and reporting of dangers is made possible via sensors, an esp32 board, and the blynk software. Monitoring vital signs ensures workers’ health, while the method seeks to raise productivity in the mining sector. Our suggested system significantly contributes to improving safety in the mining industry by utilizing cutting-edge technology and creative solutions

This study investigates the effects of B20 and additives added to the B20 blend when run in a CRDI engine under different loading conditions. Experimental studies compared to diesel show the poor performance of B20. The addition of DMC (dimethyl carbonate) and DEE (diethyl ether) in B20 significantly improved. Under high load conditions, the performance characteristics of BTHE of B20 DMC are relatively higher and lower BSFC than B20 DEE values. It can be seen from the emission results that NOx emissions are higher due to proper combustion in the case of B20 DMC. The emission characteristics show that B20 with 5% DMC showed better results than other samples present. This happens because of better and proper combustion of the fuel. It showed better results in the emission of CO and hydrocarbons while the DEE sample at 600bar showed better results for smoke emission. The combustion characteristics also show the same result that B20 with 5% DMC is a better fuel when compared with the rest of the samples. Though in performance characteristics we noted that B20 with 5% DEE showed better results in the graph between crank angle vs cylinder pressure and crank angle vs heat released.
