爆破技术是井巷掘进工程中的重要环节,而放炮的成败又是爆破工程的首要关键。瞎炮的产生,不仅直接影响循环进尺和循环率,而且处理瞎炮常给施工人员造成安全威胁。但是,在工程实践中,瞎炮还是经常发生的,甚致严重影响着循环的正常进行,在目前缺乏对瞎炮产生原因的系统积累资料和综合分析研究,故也就无法制订相应的防范措施。正是鉴于上述情况,我们在江苏煤建公司一处的支持下,就马坡矿在雷管 Blasting technology is an important part of tunneling engineering, and blasting success or failure is the primary key blasting project. Blind cannon production, not only directly affect the cycle footage and cycle rate, but also to deal with blind artillery often pose a security threat to the construction workers. However, in engineering practice, blind guns often occur, even severely affecting the normal cycle, in the current lack of systematic analysis of the cause of blind artillery accumulation and comprehensive analysis, it will not be able to formulate appropriate preventive measures . It is in view of the above situation, we have a coal company in Jiangsu with the support of the Ma Po mine in the detonator
