Limestone Extraction Without Drilling and Blasting Agg-Net

For years, the limestone was extracted by drilling and blasting and then wet processed into clinker in the cement plant. In a move to increase productivity and reduce costs, IFCEM became the first cement plant in the Ukraine to initiate the transition from the wet process to a dry process, a measure that optimized the mining method for material supply. The dry process is now considered the

Blasting Safety Revisiting Site Security

blaster usually understands that in a given surface or underground mine, blast area could vary from shot to shot. There are many occurrences of flyrock landing beyond the property or permit boundary in surface blasting. Such occurrences demonstrate incorrect determination of the bounds of the blast area. Flyrock from a limestone quarry traveled about 930 ft and fatally injured a resident who
