摘要
本文探讨了影响煤矿作用毫秒延期电雷管延时精度的一些因素。通过试验和生产实践证明:在原材料确定的条件下,改变延期药配方,铅管延期体引拔工艺和严格控制锑系引火药头重量,能够非常显著地提高这种电雷管的延期时间精度。
The factors affecting delay time precision of permissible MS delay electric detonators were investigated in this paper. Tests and industrial productions shown that by varying the delay compositions and draw technology of lead delay elements,and strictly-controlling the weights of Sb fuscheads, the delay time precision of the permissible MS delay electric detonators could be remarkably improved, for the given raw materials.
