Bird’s eye view with a drone camera of an opencast mine in WCL and examples of observations (marked in red) by the expert committee during virtual inspection are presented below for reference. 1.7) IIoT based monitoring of Environmental Tele-Monitoring Systems in UG mines Environmental Tele-monitoring System (ETMS) installed inside various underground mines have been integrated with ICCC. This system continuously tracks life-critical parameters such as methane, carbon monoxide, oxygen levels, air velocity, and temperature, in UG mines. This realtime monitoring ensures that any hazardous condition is detected immediately, allowing for timely intervention and safer operations. The readings of various parameters from an underground mine are tabulated below in the form as received at ICCC.
