摘要:
某铜矿矿（岩）体层理裂隙发育，巷道掘进爆破施工过程中，卷装乳化炸药装药有时比较困难，爆破效果较差。在总结巷道掘进施工问题的基础上，提出采用光面爆破技术，进行巷道掘进爆破，巷道成型较好，但装药效率低、成本偏高等。将散装粒状铵油炸药应用于掘进爆破中，通过理论分析，结合试验验证后，进行全面推广。应用结果表明：将粒状铵油炸药应用于巷道光面爆破中，能有效提高装药效率，爆破效果更趋于稳定，同时达到了降本增效的效果，取得了很好的经济和社会效益，也为在国内巷道掘进中的推广应用提供了一定的借鉴。

Abstract:
The ore(rock) body stratigraphic fractures develop in a copper mine.In the process of roadway excavation and blasting construction,it is sometimes difficult to charge roll-charge milky explosives and the blasting effect is poor.On the basis of summarizing the problems during roadway excavation construction,the smooth blasting technology is proposed for roadway excavation blasting.The roadway is well formed,but with low charging efficiency and high cost.Therefore,it is further proposed to apply bulk granular ANFO explosive in excavation blasting,and it will be promoted comprehensively based on theoretical analysis and after test verification.The application results show that the granular ANFO explosives applied in smooth blasting can effectively improve the efficiency of charging,and blasting effect is more stable.At the same time,it has achieved the effect of reducing cost and increasing efficiency,good economic and social benefits,and also played a certain reference role for its promotion and use in roadway excavation in China.
