摘要
文章通过对影响煤矿许用型电雷管可燃气安全度诸因素的分析,提出了延期元件发热量临界值和气室压力临界值的推想,并进行了客观验证。同时通过对发达国家煤矿许用型电雷管结构及工艺的探讨,提出了确保可燃气安全度的技术途径。
By analyzing the influence factors about safety degree of flammable gas of permissible electric detonator in this paper,the critical calorific value and pressure in air-room of delay element were supposed,and also being verified.The structure and technology of permissible electric detonator in developed countries were discussed,and the technology method to insure the safety degree of flammable gas is presented.
