Our Accomplishments 

  • Application of numerical modelling for simulating the caving behaviour of the overlying rock beds, predicting the caving span, convergence, closure abutment stress and estimation of support resistance. This numerical modeling on prediction of longwall roof behaviour with goaf simulation has greatly helped to overcome strata control problems, so long prevalent in longwall mines of India.


  • A method to classify the coal mine roof rock according to the caving behavior has been developed. Caving Index number has been introduced based on the stratification and the physico-mechanical properties of the roof rock layers. Based on this Caving Index number and other mining parameters the coal mine roof can be classified and the required support capacity for safe extraction of coal can be determined.


  • Introduced microseismic monitoring in mines and development of “Specific Instability Criterion” and modules in MATLAB to calculate seismic parameters has helped to quantify the degree of instability over worked out panels and previously extracted unknown workings in coal mines. The microseismic monitoring technique can be effectively used for ground control, roof fall prediction, detection of unknown workings below railway tracks and monitoring of rock burst prone mines.

  • Hard roof management by induced caving of massive and bridging rock beds by hydro-fracturing with water injection under high pressure and development of methodology for design and planning of hydro-fracturing at any locale. This has potential to improve the cavability and fragmentation of the broken rock debris in the goaf. Mining with hydro-fracturing as caving technique will improve both productivity and safety of the mines.

  • Introduction of “Oblique shortwall mining method” for fast liquidation of standing pillars in underground coal mines in India. The method was designed and implemented for the first time in India at Balrampur mine, SECL and RK-NT mine, Srirampur Area, SCCL. Extraction was successfully completed in 10 shortwall panels of Balarampur mine, and 4 shortwall panels in RK-NT with this technology.
