The Ministry of Civil Aviation, Govt. of India has accorded conditional exemption to Central Mine Planning & Design Institute (CMPDI) the use of drones for surveying coalfield areas of Coal India Ltd. for acquiring data for monitoring of various activities.
CMPDI will use drones in CIL mines for specialized survey applications in coal mines of CIL such as generation of high-resolution images, 3D terrain mapping, volumetric measurement of excavation, etc. and mapping of areas for precise delineation of zones where underground mine fires are present.
There are several applications where these drones can be used such as inspection of installations and components in inaccessible and difficult-to-reach areas for safety of men and machinery, blasting zone monitoring, etc.
CMPDI is one of the first major organizations in India to introduce Drones for various applications covering vast geographical areas.
