Laboratory Services
of CMPDIL
is a center for excellence in resource quality evaluation, beneficiation
and proper utilization of coal/lignite and minerals. Expert services are offered
with highly skilled manpower and state-of the art equipments for
characterisation of coal and lignite through chemical, petrographic and
washability route supported by coal
technologist for end use. The quality and washability data generated during the last
two decades formed the basis for deciding grade of coal in Geological Reports
and mine feasibility reports, designing of washeries, and further down stream
utilization. To meet the relate
industry’s requirement ,
continuous R&D activities
are carried out. Laboratory Division consisting of Chemical,
Petrography, Coal Preparation and CBM Laboratories unit. Services offered by each unit
is given below:

Chemical
Laboratory
Chemical
analysis of coal is essential for characterization, utilisation,
commercial grading and marketing purposes. For utillisation of coal in
different industries such as power, steel, cement, fertilizer, railways,
domestic consumption, brick kiln, textile, sugar, tea, glass, pottery, refractory, carbon
industries and other chemical industries, characterization of coal is
essential.
The broad
activity of the chemical laboratory starts from collection of coal samples
from different sources viz. coal core, ROM samples, channel samples etc to
analyse of various parameters.

Coal Petrography
Laboratory
CMPDI’s Coal Petrography Laboratory
is one of the leading laboratories of India to undertake the
characterization of coal/lignite, source rock evaluation for hydrocarbon
generation at the exploration stage, washery product, and quality control of
Indian/imported coal . Coal Petrography study is essentially microscopic study
of coal (maceral composition, vitrinite reflectance & v type distribution
) which plays an important role for blending of coal in
coke making and charaterisation of coking and non-coking coal for its
end use .
The Coal Petrography Laboratory from time
to time has upgraded itself with the induction of state of art automatic
equipment for rapid/detail determination of both organic and inorganic
constituent of coal. It is only laboratory in India to achieve accreditation
of ICCP (International Committee for Coal Petrography).
With its highly trained and dedicated
manpower and sophisticated/imported equipment, the Laboratory is in a position
to undertake following analysis :
-
Coal
characterization for coal exploration,
washery product control, blend studies for coking as well as for
non-coking coals
