I'm excited to share a new milestone in my mine planning journey. On 27th March 2024, I had the privilege of presenting the first Underground (UG) Mine work utilizing Continuous Miner technology for mass production at Mahanadi Coalfields Ltd. This project not only marked my inaugural foray into Underground Mine planning but also the first project of its kind for Regional Institute-7, CMPDI. Taking on the challenge of executing this new work in a short span of time was both exhilarating and rewarding. The appreciation and acknowledgment received from the Directors and esteemed members, deeply humbles, and energizes me. Their recognition not only validates our collective efforts but also underscores the unwavering commitment invested in delivering the Underground project using continuous miners. I extend heartfelt gratitude to CMPDI HQ Underground Mine Division and the guiding luminary, Mr. Pramod Kumar Sir, GM (Mining), for the invaluable support and guidance. The mentorship was instrumental in navigating the complexities and ensuring the success of this endeavour. To provide a glimpse into our work, I am pleased to share a video showcasing our Underground Mining strategy deploying Continuous Miners. This strategy was implemented in a challenging environment, with an active open-pit working overhead, contiguous seams, depillaring extraction percentage, thin partings, goaf-setting time presenting unique complexities and considerations. #MinePlanning #UndergroundMining #ContinuousMinerTechnology #MahanadiCoalfieldsLtd #RegionalInstitute7 #Teamwork #CMPDI #CoalIndiaLimited

It is interesting to see the animation but a few basic concerns are appearing in the design namely : 1. The panel width (considering 6 pillars of 45.5 m centre) leads to 270 m which may impose caving issues; 2. Coal % extraction from SOP (is this optimum?) 3. Snook design is not considered where the last slice in the fender will lead to uncontrolled failure. I believe the above needs to be looked into for a safe & optimised design.

Congratulations, Dr. Pritam Biswas, on your successful utilization of Continuous Miner technology for mass production at Mahanadi Coalfields Ltd. Your dedication and expertise shine through in your work, and I look forward to learning more from your future endeavors. My submission for the sequence of depillaring - 1. It would have taken the help of Rock Mechanics too to calculate the equal distribution of load on the roof of Goaf. 2. The dewatering vis-a-vis dip would have been taken due care in deciding th S-O-Dp 3. The side districts created for depillaring may be slightly angular to win more of the left over insitu coal which seems to be more left over in case of parallell one. Hope my points are admissable. Happy learning.

Nice to watch.. Only suggestion is to just add Strata Monitoring instrument at Junction, Tri Junction & Mid of split & mid of level gallery. 😅 Otherwise there will be a violation of Depillaring permission.
