摘要:
为解决井下矿乳胶基质远距离配送、长期储存后出现的析晶问题，依托刚果民主共和国民爆产能项目现有实验设施，在原有井下矿一体化复合油相材料的基础上，外加不同的高分子乳化剂改良复合油相，并在水相中添加硝酸钠以降低析晶点。对比分析了优化前、后乳胶基质的黏度指标、储存性能、远程配送抗颠簸性能、常温敏化及爆炸性能，并且在刚果民主共和国某地下铜矿开采中对新生产的乳胶基质进行了试应用。结果表明：在一体化复合油相的基础上外加高分子乳化剂，同时在水相溶液中添加硝酸钠，有利于提升乳胶基质的自然储存性能和抗颠簸性能；在相同水相成分和配比条件下，外加乳化剂KE3013B和乳化剂BEF制备的乳胶基质的自然储存性能和抗颠簸性能差别不大, 但均优于乳化剂CR30N制备的乳胶基质；制备的几种乳胶基质在30～60 min内均可实现常温敏化；外加KE3013B和BEF制备的乳化炸药的爆炸性能优于外加CR30N制备的乳化炸药；新制备乳胶基质的巷道装药爆破平均有效进尺率达到87.5%。
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 temperature, 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 prepared emulsion matrix in tunnel charge blasting could reach 87.5%.
