Effect of seasonal changes on overburden stripping in limestone quarry Available to Purchase

This paper examines the influence of seasonal changes on stripping of overburden in West African Portland Cement (WAPCO) Shagamu, Nigeria. In order to achieve this tonnage of overburden moved per mouth, tonnage of exposed and workable limestone available for blasting were determined during dry and rainy season for 3 years. The results showed that overburden stripped vary from 292,000 tons to 303,000 tons and 195,000 tons to 211,000 tons during dry and rainy seasons respectively. Also, the tonnage of exposed and workable limestone varies from 2.07 million tons to 2.61 million tons and 1.5 million tons to 1.517 million tons during dry and rainy season respectively for 2004-2006. Therefore, stripping of overburden should be compensated during dry season to maintain the level of production.
