Abstract:
Wastages, energy loses, low production and environmental impacts
are the major problems associated with quarry mines and s. It is essential to
minimize these problems to optimize profit and to make a better working place. A
Cleaner Production (CP) assessment was performed in quarry and crusher plant
located in Nochchiyagama, Sri Lanka. The objective of this project was to identify
and provide suggestions to reduce wastages and energy losses, reduce
environmental impacts, and provide optimum installation criteria of and to
optimize the explosive usage of the quarry with enhanced profit/benefits. The
whole operational process was divided in to five sections, i.e. material balancing,
energy survey, chain survey for , assessment of environmental aspects and rearranging
blasting parameters according to Uniaxial Compressive Strength of rock
in quarry mine. After implementing the CP, the solutions / suggestions of turning
off generator after starting the plant, introducing cone nozzles to the , covering the
conveyor belts, reducing powder factor, etc, was made and they were given to
client. The expected annual saving of the CP implementation was Rs.3, 168,895.89
with number of other intangible benefits.
