摘要
文中对影响煤矿许用毫秒延期电雷管沼气安全性与延期时间精度的因素进行了研究。应用正交设计研制了新的延期药配方，确定了合理的雷管结构及装配工艺参数，产品性能达到ＧＢ８０３１《工业电雷管》的规定。
In this peper, the influence factors which affect the safety against methane and time delay precesion of permissible MS delay electric detonator are investigated. New delay compositions are formulated by the use of orthogonal design, resonable construction of detonator and technological parameters for assembly are determined and the quality of the product comform with that designated by the speification GB8031 for industrial electric detonator.
