The
client
Indian
Aluminium Co Ltd (INDAL)
Talabira
coal project, Sambhalpur, Orissa
A major producer of aluminium and
its finished products, INDAL is a vertically
integrated company with its own bauxite
mines, alumina refinery, aluminium smelters,
power plants, coal mines, sheet and foil
rolling mills and aluminium extrusion
plants, spread all over India.
INDAL wanted to implement CRYSTAL to suit
its mining practice at the Talabira Coal
Project. This project uses surface miner
for extraction of coal with proper quality
control. Geophysical loggers are being
used to infer calorific values down the
hole in production-stage-drilling.
INDAL required a software that is tailored
to match such practices at the mine site
and reposed confidence in CMC, based on
our past record.
Project
details
Crystal uses geological exploration and
survey data to generate a three-dimensional
block model of mineral reserves. The model
is then estimated for assay variables,
using either the enhanced inverse square
distance method, Kriging, or both, to
have two different estimates for each
block. The block model is then used to
analyse whether the mineral is economically
viable for mining.
Crystal
software is used to carry out critical
planning and quality-control jobs on a
day-to-day basis. It also does survey
calculations and volume computation, including
daily updates of the excavated 3-D block
model from survey data.
The
software provides an interface to almost
all electronic total stations and EDMs.
It even allows keying in of manually recorded
survey data from theodolites. This data
is then used to calculate the X, Y and
Z coordinates of the surveyed features.
Crystal
can generate mine maps on any scale. It
has a module devoted to geo-statistics,
with which the user can carry out geo-statistical
calculations on either raw borehole data
or filtered data from the 3-D block model.
The user can view the mineral reserve in
three dimensions. This module uses the Open
GL graphics library to provide the user
with state-of-the-art graphics.

CRYSTAL
has been installed and implemented for
INDAL's new Talabira coal project in the
Sambhalpur district of Orissa. It will
supply coal to the company's captive power
plant at Hirakud, in Orissa.
The
software meets the requirements of mine
survey, geo-modelling and production planning
for the long term, as well as for day-to-day
mine operations. It helps in production
planning, while taking care of the stringent
quality requirements of the power plant.
It also schedules sophisticated mining machinery
like the state-of-the-art surface miner
and ripper dozers, increasing the productivity
of these capital-intensive machines.
