近年来,务川汞矿成功地实施了“中孔分段一次崩矿”采矿方法。该方法已于1983年4月进行鉴定,大家认为该连接法操作简易,安全可靠,经济合理,是先进的起爆新技术。现将几个操作技术与安全管理对策介绍如下。 (一) 同步、复式、并联起爆网路 1980年,我矿就将塑料导爆管非电起爆系统用于掘进及浅孔采矿,在浅孔留矿分层爆破中由一次使用几十发到数百发,为中孔大爆破打下基础,经反复完善成为目前基本定型的导爆索-导爆管混合系统的同步、复式、并联起爆网路。网路连接方法见图1。
In recent years, the Mochuan mercury mine has successfully implemented the “Mid-hole sub-section collapse process” mining method. The method has been identified in April 1983, we believe that the connection method is simple, safe, reliable, economical and reasonable, is an advanced detonating new technology. Now a few operational techniques and safety management measures are as follows. (A) synchronous, duplex, parallel detonating network In 1980, I mine the plastic detonating tube non-electric detonating system for excavation and shallow hole mining, stratified mining in shallow hole blasting by a dozen to Hundreds of hair, laid the foundation for the large-scale blasting in the hole, after repeated improvements to become the basic stereotypes detonating cord - detonating tube hybrid system of synchronous, duplex, parallel detonating network. Network connection method shown in Figure 1.
