Gelatinous permitted explosive

The method of mining is somewhat like driving two sets of tunnels at right angles through the strata. Most mines of this type do not present any hazard from methane and therefore non-permitted explosives can be used. The selection of powder or gelatine type of explosive depends on the nature of the rock and particularly on the wetness of the mine.

Many permitted explosives are ammonium nitrate in powder form or gelatinous explosives with added inert salts such as rock salt or potassium chloride which reduce their explosion temperature.
