DAYAGEL PERMITTED emulsion explosive is a detonator sensitive, P1 permitted explosive designed for application in underground coal mining. It is white in color and is plastic wrapped with steel wire end clips. Cartridges are identified individually as PERMITTED, P1 explosives with a PERMITTED logo, the average mass per cartridge, country of manufacture and identify of manufacturer.

Safety

Because of the intimate nature of mixing of the ingredients in DAYAGEL PERMITTED the explosive is extremely efficient which results in lower fume levels than for nitroglycerine based or water gel explosives. This makes DAYAGEL PERMITTED well suited to underground blasting situations.

Users should note however that ventilation standards must be maintained and that personnel must not re-enter the mine workings until the required level of ventilation has been reached.

DAYAGEL PERMITTED has very low mechanical impact sensitivity.

If exposed to fire, DAYAGEL PERMITTED will self extinguish unless a vigorous external source of heat is applied.

Whilst DAYAGEL PERMITTED does not burn easily it should be kept clear of flame or excessive heat.

If DAYAGEL PERMITTED remnants are to be destroyed by burning, advice on the correct method should be sought from DAHANA Engineering Center located at DAHANA offices, or from the local explosives statutory authority.

Applications

DAYAGEL PERMITTED explosive can be used in all situations previously encountered with ‘MORCOL’ or ‘AJAX’ PERMITTED explosives. However due to its greater water resistance DAYAGEL PERMITTED is particularly suitable in wet conditions where the explosive may be exposed to water for many hours before the blast is fired.

Fume Characteristics

Product is oxygen balanced and is suitable for underground use.
