I'm not familiar with any use of C4 in mining or the commercial explosives industry. Primarily, I suppose, because of the cost. You will probably get better information from another source. Sorry, that wasn't much help.<br>

The "deflagration index" is a parameter used in tests conducted according to the ASTM E l226 "Standard Test for Pressure and Rate of Pressure Rise for Combustable Dusts"<br>

Sorry, I haven't had much u/g experience and don't know exactly what you are talking about. However most emulsions that I'm familiar with are adversely affected by detonating cord especially in small diameter holes. Any special reason on why you wish to use det cord?<br>
