FACTORS DRIVING CONTINUOUS BLASTING IMPROVEMENT AT THE LAFARGE RAVENA PLANT

摘要

The Lafarge Ravena Cement Plant in Ravena, New York demonstrated continuous and extraordinary improvement in productivity during the past several years. The factors driving continuous improvement at the Lafarge Ravena Plant include:1) Management techniques including regular scheduled and effective Blasting Optimization Team meetings.2) A real time blasting database to guide blasting product and procedure decisions. Key decisions involved all levels of quarry and blasting supplier personnel and a close working relationship between production and blasting areas of expertise was demonstrated.3)Blast optimization and optimization of quarry operating parameters such as blast location relative to crusher location, hours worked, etc. A statistical analysis has been conducted to quantify and understand the effects of blasting changes and other factors to determine the factors involved in productivity improvement. The statistical methods developed for this analysis and the management techniques described in this report can be used in other locations to guide continuous productivity improvement and achieve operating efficiencies in a wide variety of quarry operations.
