Please describe in detail including the TRL Level:
IIT(ISM) in collaboration with Jaya Bharat Equipment Pvt. Ltd (JBEPL)., Hyderabad has made a breakthrough in mining technology innovation by designing and developing Self-Advancing (Mobile) Goaf Edge Supports (SAGES) under the Make in India flagship programme of Govt. of India. The project was funded by the Ministry of Coal. A team headed by Prof. U. K. Singh (Project Leader) Prof. Dheeraj Kumar (Co-Principal Investigator), Deptt of Mining Engg., IIT (ISM) Dhanbad and Mr. N. V. N. Reddy, Managing Director, JBEPL have designed and developed a light weighted, medium duty 2X200t capacity SAGES with remote radio controlled and digital display system. This indigenous state-of-the-art machine can be used as a smart breaker line support system for safe extraction of locked coal in standing pillars (depillaring) in underground coal mines through effective roof control and proper support design. After the successful field trial of SAGES at RK7, mines of Singareni Collieries Companies Limited (SCCL) the Directorate General of Mines Safety (DGMS) has approved for the full scale deployment in underground coal mines. Currently, mining operations are being carried out efficiently with this machine in RK7 mines of SCCL. By embracing SAGES-enabled operations, the Indian mining industry can improve its productivity significantly by improving the % extraction of locked pillars and reduce ground failure fatalities and injuries in the mines. This technology is economic, eco-friendly and more safe, and therefore, it can be game-changing for Indian mining industry, if deployed at scale. Experts of the field believe that SAGES will definitely mark a significant shift in the way mining works. The above technology is presently developed at TRL 9 and ready for deployment. The Industry collaborator, JBEPL is waiting for the orders from Coal Companies. Manufacturing in bulk can be made at JBEPL Workshop in Hyderabad.


Applications: This indigenous state of the art machine can be used as a smart breaker line support system for safe extraction of locked coal in standing pillars (depillaring) in underground coal mines through effective roof control and proper support design The system can be used as Breaker-line support systems as well The Machine can also be used as Gate Road Support system in Longwall
Advantages: Keeps support personnel away from active mining areas. Withdrawal and setting of the SAGES are done from a remote place up to 30m from the active mining area. Overall cost of the existing support will be less with SAGES. Provides active roof support ensuring more Safety. Persons can work more confidently under the coverage of huge support capacity of the SAGES. Increase in percentage of coal extraction from coal pillars facilitates regular caving of the roof strata. Eliminates the need for installation of separate strata monitoring and warning indicators at coal faces as they are in-built in SAGES.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
