对点火爆破的最根本的改进是要达到全面的电气化,因为,只有电气化点火才能够彻底消除点火作业的危险和保证不被胶引烟毒损害,而且也才能够跟上矿山高度机械化的大量开采的水平。现在供各矿山能够采用的工业电雷管,实际上不能被广泛地应用在矿山各种采掘面的爆破作业中,此外它的成本也比使用火雷管高得多。为了更能适应一般矿山的技术经济条件,而从比较另一种在工厂已经成为出产品的点火帽的基础上改进成为本文所介绍的电胶引。它的主要特点有如下几个: The most fundamental improvement to spark blasting is to achieve full electrification because only the electrification ignition can completely eliminate the danger of ignition operation and ensure that it is not damaged by glue poisoning and can only keep up with the high mechanization of mining s level. The industrial electric detonators now available to all mines can not actually be used extensively for blasting operations on various mining surfaces, and their cost is much higher than the cost of using fire detonators. In order to better adapt to the general technical and economic conditions of mines, but from the other in the factory has become a product of the ignition cap based on improved into the introduction of this article. Its main features are as follows:
