煤矿许用毫秒电雷管沼气安全性研究

文中介绍了提高８号覆铜壳煤矿许用毫秒电雷管沼气安全性能所作的研究结果，叙述了所建立的光电测试系统和对引火药头，铜延期体进行的测试，以及根据这些结果安排的沼气安全性试验。在全面研究了影响沼气安全性诸因素的基础上，提出了提高８号覆铜壳煤矿许用毫秒电雷管沼气安全性的具体措施。

Experimetal Study on Safety with Mathane of Permissible MS Electric Detonators in Coal Mines

In this paper, an introduction is given to the increasing safety with methane 8# permissible MS electric detonators with clad copper steel shells, the devoloped photoelectric measurement system, the measurements of delay element, igniter and experiments on safety with methane are also described. A new scheme in increasing safety with methane of permissible MS electric detonators was putted forward hosed on the experiments, results of factors affecting safety with methane.
