Underground Mines - Areas of Involvement

Developed guidelines for optimisation of blast design parameters at Malanjkhand Copper Project, Rampura Agucha of HZL and Wadi Limestone Mine of ACC, with improved fragmentation, reduced explosive consumption/specific drilling, and reduced environmental impacts due to blasting.
Designed the optimum shape of shaft and nature of support for deepening of Mallappa shaft, Hutti Gold Mines Ltd.
Evaluated the ground stability at Rajpura-Dariba mine, Hiustan Zinc Ltd, and studied the feasibility of depillaring of rib pillars and crown pillars at Zawarmala mine (HZL).

For the purpose of support design at Tandsi mine, WCL, and at Adriyala Block, SCCL, We carried out multi-stage triaxial compression tests using Hoek triaxial cell as per international guidelines.
As part of an S&T project, we designed non-conventional pillar dimension for working steeply dipping coal seams in Singareni coalfields, AP. This is first of its kind, and the experimental panel was extracted successfully without any ground control problems. Based on the recommendations from these studies, other panels with similar conditions are also being extracted in the same way.
We helped in introduction of the first continuous miner in SCCL mines for fast extraction of coal seams
Seismic and microseismic investigations have been carried out first time in the country to assess the stability of underground mine workings at Rajendra mine, South Eastern Coalfields Ltd..
