IMPROVEMENT AND COST ANALYSIS OF BLASTING OPERATIONS AT WESTERN LIGNITE OPEN CAST MINE
Drilling and blasting operations have a great importance in mining operations. By means of drilling and blasting operations, ease of excavability is provided and production can be made in desired particle sizes especially for ore. In this study, state-operated blasting operations in Western Lignite Corporation mining sites and problems encountered in these blasting operations are investigated. It was aimed to solve the problem of encountering blocks after blasting by using nitroglycerine based cast boosters instead of emulsion based cast boosters. The blasting shots and excavation loading works in the blasting area were recorded. The muckpile images obtained after blasting operations were examined with WipFrag software and particle size distributions were checked. According to the data obtained, cost analyzes related to blasting and transportation were performed. It was found that after the change, the problems decreased and the company economically gained 25% annually in terms of blasting costs.
