CMPDI develops coal excavation measurement method

RANCHI: The Ranchi-based Central Mine Planning and Design Institute (CMPDI), in collaboration with National Remote Sensing Centre (NRSC), department of space, has developed a methodology for rapid and accurate measurement of excavated volume of overburden/coal in opencast coal mines using Light Dedtection Ranging (LiDAR) Technology.

The project was funded by Coal India Ltd under R&D activities for the total outlay of Rs.3.88 crore. High resolution stereo satellite data, Airborne Laser Terrain Mapper (ALTM) and Terrestrial Laser Scanner (TLS) were used for generating the digital terrain model (DTM) of the pilot study area in Belpahar.

The methodology developed under the project is being used in the coal industry. TLS provides detailed and highly accurate 3D data rapidly, accurately and efficiently, which has wide ranging application besides coal mining in the field of architecture and facade measurement, archaeology and cultural heritage documentation, topographical mapping, city modelling, highway and civil engineering etc.
