Abstract: Mining activities releases toxic and very harmful gases. This causes a lots of pressure in the mining industry. Thus to increase the productivity and reduce the cost of mining along with the consideration of the safety of workers, an innovative approach is required. A real time monitoring system that using WSN, in which there are multiple sensors. This system monitors surrounding some environmental parameters such as moisture, toxic gases and land sliding with the help of two wireless sensor nodes using IoT. This system displays the parameters on the Monitor at the underground section, where sensor units will be install as well as on the monitoring unit. It will be helpful to all miners who present inside the mine to save their life before any causality occurs. An alarm will triggers when the sensor values crosses the threshold level. This system also stores all the data in the computer for future inspection.
