After an advent of internet of things (IoT), the entire dynamics of this world has been changed so rapidly. Being a student of science and technology, it is very much essential for us to think about the potential alternatives for social issues. In this regard, one may notice that there are thousands of people who die annually in the coal mines of Pakistan and rescue team cannot help in any way. This is one of the most emerging issues right now in other developing countries too where extraction of minerals from in depth mines is going on. This paper identifies this issue and suggests the prototyping of pro-active IoT-enabled wearable gadget for the smart surveillance of coal miners within the mines of Pakistan. This wearable IoT device not only monitor the hazardous gas, pulse rate of miner, humidity and temperature conditions within and exact altitude where miner is working currently but it will also provide a pro-active control to miners to generate any sort of query they face while working within the dark and depth mines using error palette. This entire data will be received at a specific Internet protocol (IP) using internet broker. This will also help the rescue officers to decide their rescue flow accordingly. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
