| 摘 要： | 在岩溶发育区进行深孔台阶微差爆破,溶洞和裂缝可能贯通相邻炮孔,先爆孔产生的冲击波,容易通过裂缝殉爆后爆孔的装药,从而破坏起爆网络,产生拒爆.本文通过某石灰石矿爆破实例,分析了在岩溶发育区采用电雷管--导爆索起爆网路进行深孔台阶微差爆破时,岩溶裂隙引起相邻孔装药殉爆,进而产生拒爆的原因,并提出了克服此类拒爆事故的有效措施.

| Abstract: | Borehole of long hole bench millisecond blasting in Karst-developed area is transfixed by karst cave and cranny. Charge of other borehole is blasted by shock were of earlier blasting boreholes through cranny, consequently priming circuit is destroyed and misfire is brought, Based on some blasting of certain limestone mine in this paper, reason of produced misfire of karst cave and cranny brought about sympathetic detonation of neighbouring boreholes is analyzed. Some good measure of prevent misfire is advanced, |
