Significant researches have been carried out in the areas of rock mechanics, ground control, mining methods, stability of slope and waste dumps, mine ventilation, mine fire, rock fragmentation by blasting, explosives performance, drillability of rocks, substitutes of explosives, slurry transportation in pipelines, underground and surface mine environment, and mines safety. A large number of research papers have been published in national and international journals. Outcomes of the research work have significant impact on mining and allied industries.
It is significant to note that the Department undertook shaft pillar stabilization at Mudidih Colliery of BCCL, and was successful in its efforts. The Department has also successfully closed the water flow through the fissures in a coalmine of BCCL, and saved several lakhs of rupees worth of power being consumed in pumping. There are many more such laurels, which the Department has brought to the credit of the School through its R&D efforts. |

|
|
| Objective
|
Development of an integral approach for selection of the capacity of powered support and formulation of a strata and support behavior and monitoring scheme for longwall operation in Indian coal mines. |
|
|
| Status
|
On-going |
|
|
| Findings
|
• Literature review related to strata control in the longwall panel is complete
• Field data of worked out panel compiled
• Numerical modeling approaches have been developed for simulating progressive caving and load on the powered roof support in longwall mining.
• A Data Logging System has been developed for use in monitoring of pressure in legs of hydraulic powered roof supports and closure of the support.
• Numerical Modeling: Numerical modeling approaches have been developed for simulating progressive caving and load on the powered roof support in longwall mining.PhD degree has been awarded for this research work to Dr. Gauri Shankar Prasad Singh, Lecturer, Dept. of Mining Engineering, IT-BHU, Varanasi.
• Data Logging System: A Data Logging System has been developed for use in monitoring of pressure in legs of hydraulic powered roof supports and closure of the support. The Data Logging System has been installed in F6 longwall panel of Moonidih Project for trial in Nov. 2007. The data logging system consists of XR5-SE-M data logger in FLP-WP enclosure with intrinsically safe pressure transmitters, wire type potentiometer displacement transducers, IS power supply and rugged notebook PC. Except the rugged notebook PC, the data logging system has been installed in the support at the longwall face of the panel F6. It advances along with face support.

Development of a setup for stress measurement in concrete tunnel lining dam walls and pillars |
|

|
|
| Objective
|
Development of a strain gauge based device for mounting on wall for measurement of absolute stress in concrete tunnel lining, dam and pillars |
|
|
| Status
|
On-going |
|
|
| Findings
|
A prototype strain gauge device has been developed. The strain gauge device consists of a resin block (of near elastic compound) with standard strain rosette (45o 3- element rosette) embedded into it.
A test rig is developed for confining the model rock samples and to induce stress in the modeled rock samples.
Based on the results obtained during these full scale laboratory tests, calculation for the back stress is also made. The calculated back stress closely matched with the applied stress in the concrete block. The results were quite encouraging.

|
|
|
| Objective
|
To develop design and implement an innovative concept for reducing the energy consumption in main mine ventilation fans.
To carry out several trial runs and finally demonstrate the conservation of energy in main mine ventilation fans.
|
|
|
| Status
|
Completed |
|
|
| Findings
|
The study of energy consumption profile of main mine ventilators indicates that the overall efficiency of these fans is generally less than 405 in most of the cases. The efforts should be made to increase the overall efficiency to at least 70% for reducing the energy consumption and optimal utilization of the ventilation system.
