Process Optimization and Application of Mixed Emulsion Explosives for Underground Mines
摘要
Abstract
Emulsion matrix used for underground mines may experience crystallization problems after long-distance distribution or long-term storage.Utilizing the existing experimental facilities of the Democratic Republic of Congo(DRC)indurstrial explosive project,different polymer emulsifiers were added to the integrated composite oil phase material used for underground mines to improve the composite oil phase,and sodium nitrate was added to the water phase to reduce the crystallization point.Viscosity,storage stability,remote delivery anti bounce performance,sensitization at room tempera-ture,and explosion performance of the emulsion matrix after formula optimization were analyzed.And a trial application of newly produced emulsion matrix was carried out in an underground copper mine in DRC.The results indicate that the new formula is beneficial for improving the natural storage performance and anti-bounce performance of emulsion matrix.Under the same water phase composition and ratio conditions,the natural storage performance and anti-bounce performance of emulsion matrix prepared using emulsifier KE3013B and emulsifier BEF are not significantly different,but both are superior to emulsion matrix prepared using emulsifier CR30N.Newly prepared emulsion matrices can achieve sensitization at room temperature within 30-60 minutes,and the explosive performance of emulsion explosives prepared by KE3013B and BEF is superior to that of emulsion explosives prepared by CR30N.The average effective rate of advanced depth of the newly pre-pared emulsion matrix in tunnel charge blasting could reach 87.5%.关键词
