Cleaner production assessment of a quarry mine

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.
