Deposit Type

  • Sediment-hosted


Summary:

Rampura Agucha is a stratiform, sediment-hosted Lead Zinc deposit, occurs in Pre-Cambrian Banded Gneissic Complex and forms a part of Mangalwar complex of Bhilwara geological cycle (3.2-2.5 billion years) of Archean age and comprising of magmatites, gneisses, graphite mica schist, pegmatite and impure marble. The rocks have been subjected to polyphase deformations and high-grade metamorphism. The deposit lies in the contact zone of Mangalwar - Sandmata complex and along the major NE trending Delwara lineament and predominantly covers southeast plain of Ajmer and Bhilwara.

The deposit has been broadly domained into four discrete zones, referred to as; ‘south ore’ (zone 1); ‘core ore’ (zone 2); and ‘north ore’ (zones 3 and 4). The basis of the zones is the reasonably distinct variations in the zinc grades along strike. Furthermore, the relationship between lead and silver between the northern and southern zones shows a markedly different regression profile.

The graphite-mica-sillimanite schist hosts the economic mineralization in the Rampura Agucha deposit. The economic minerals in order of decreasing abundance along with their ranges are:
• Sphalerite (15-20%)
• Pyrite (15-18%)
• Pyrrhotite (12-14%)
• Galena (1-2%)
• Sulphosalts (0.1-0.2%)

The deposit extends over 1,550 m along strike and has now been intersected to a vertical depth of 1,100 m below surface. The horizontal thickness varies between a few metres to 80 m, ........


Mining Methods

  • Longhole open stoping
  • Cemented backfill
  • Paste backfill


Summary:

Rampura-Agucha underground (RAUG) Mine development work commenced in year 2010 and started ore production through underground stoping operation from August 2013 onwards. As planned, Underground mine operated concurrently with the open pit mine till March 2018, and after completion of open pit operation, open pit area is being used to support underground mine operation in terms of material (ore and waste) handling, and infrastructure requirement like ventilation, dewatering, etc.

Lateral development (ramps, footwall drives and stope cross cut drives) activities in underground mine are being carried out through drilling holes in the rock by using development drill machines. Charging of holes is being carried out by conventional method with cartridge explosives and as well as mechanized method with bulk emulsion. Perimeter or pre-split techniques are also considered on case to case basis, in development drives to minimise over break and damage to surrounding rock. After drilling and blasting operation, the blasted rock materials are transported through mechanized means using appropriate capacity equipment like LHDs (Load Haul Dump) and LPDTs (Low Profile Dump Truck) / Mine trucks. Vertical development activities in mine are being carried out by conventional method like drop raise technique and also by mechanized means with raise borer machine.
