Sindesar Khurd Mine (SKM) is a world-class silver-rich mine with state-of the-art infrastructure facilities and best-in-class mechanisation. SKM is today one of India’s largest underground mines.
India’s first battery electric vehicle deployed in an underground mine at Sindesar Khurd. Identified green fuel suppliers and initiated usage for mining fleet. Signed MoUs with various manufacturers to introduce battery-operated vehicles in UG operations. |

Summary:
Sindesar Khurd deposit is in the central part of the eastern limb of the major Dariba-Bethumni synformal fold and the Sindesar Khurd Mine is in the central part of the eastern limb of the fold. The best exposed rock unit in the area is interbedded mica-schist / chert / quartzite and forms a prominent NNE-SSW trending ridge. This is a lenticular orebody with multiple lenses surrounding the main orebody. The economic concentrations of lead-zinc-silver mineralisation are hosted by calc-silicate bearing dolomite and graphite mica schist. The host rock is completely concealed about 100 below the surface. The economic concentrations of lead-zinc-silver mineralisation are hosted by calc silicate bearing dolomite and graphite mica schist. The host rock is completely concealed about 100 below the above unit. The rock types of the area as follows:
- Quartz Mica Schist with bands of chert/quartzite;
- Graphite Mica Schist with Fe-Pb-Zn sulphides;
- Calcareous Garnet Biotite Schist with dolomite;
- Calc Silicate Bearing Dolomite with Fe-Pb-Zn sulphides;
- Calcareous Quartz Biotite Schist;
- Basement Rock (Feldspathoid schist/gneisses).
Base metal deposits of various sizes and grades occur throughout the belt in calc-silicate bearing dolomite and graphite mica schist horizons, the latter in general containing low grade disseminated sulphides of large volumes. At the south end of the belt, contains multi-metallic sulpho-salt association.

Mining Methods
- Blast Hole Stoping
- Paste backfill
- Hydraulic backfill
Summary:
The deposit is concealed 100m below the surface and thus amenable to underground mining only.
Due to shallow depth of deposit and low cost of production with decline mining by trackless operations, it was decided to open North decline/ramp for ore production with secondary access via incline. Further, with expansion of mining operation, south decline/ramp was developed to add to ore production capacity.
Development and Stoping method
The Ramps are connected with Levels by development of an access cross-cut and footwall drives of size 5.5m X 5.0m. In a mining block, footwall drives are developed at all levels in the block. The stopes at levels shall be connected through footwall drives with access crosscuts. Slot X-cut shall be developed at the widest section of the orebody. Number of ore drives for production drilling shall be excavated along the strike depending on the width of the orebody. Stoping is done by blasthole Stoping method. In the blasthole stoping method, slot is opened at the widest portion of orebody and rings are retreated towards the end of the stope. The muck is then withdrawn at extraction level through LHDs and then directly loaded in to mine trucks for hauling through ramps from underground to surface stock yard. From stock yard, ore is fed to the primary crusher using surface dumpers through haul road after sizing with hydraulic breakers.
Mining will be done using trackless operations up to -55mRL level using both ........
