Complete detonation results in a minimum of flame, a point of first importance with those explosives intended for use in the presence of inflammable gas or coal dust. Electric blasting caps or other detonators too weak to detonate completely a charge of high explosives may generate sufficient heat to ignite it.

The effect of a detonator on a charge of high explosives in a bore hole is not infinitely powerful, but decreases with distance. It is, therefore, easy to understand the necessity for using detona tors strong enough to ensure the eflect of the detonator being felt throughout the charge. It might be understood from this that the detonator should be located {in the center of the charge; this would be considered correct had not numerous tests shown that the greatest effect of the detonator is produced straight away from its loaded end and m a line with its long axis. For this reason it is advisable to have detonators pointed toward the main part of the charge or to use not less than two electric blasting caps in deep bore holes so that there is no danger of the diminishing force of the detonators failing to detonate completely the entire charge. This use of several detonators in a single large charge acts also as a safeguard against the danger of an occasional broken wire. The electric blasting caps should not be farther apart, in deep holes, than from twenty to twenty-five feet and for the lower strengths of insensitive explosives it is better to have them even closer to each other.
