BULK EMULSION EXPLOSIVE - A CASE STUDY - Effect of Type of Explosive and Blast Hole Diameter on ...

usually limestone although many variations exist. is the predominant raw material open cast mining method has been recognized as …Sweden where Bulk Emulsion Explosives have been used. A comparison is made with other types of explosives re garding costs for drilling and blasting. By using Bulk Emulsion Explosive it was possible to achieve a better breakage performance. In a copper mine this resulted in a decreased powder factor and thereby less cost for the explosive.cost for the explosive. In a limestone quarry an expansion of the drilling pattern lowered the drilling cost and the change-over to Bulk Explosive made handling and storage more adventageous. The studies are made for a surface copper mine using large diameter (251-310 mm) drill holes and a limestone quarry using small diameter drill holes (95 mm).Lehigh Portland Cement CompanyLehigh Limestone Quarry Explosives Detonation.
