KoolKap® Charge Bags are a self-contained decoupled charge for use in the larger diameter blast holes of open cut mining, especially coal and iron ore mines. They can hold up to 100kg of product and the booster/primer can be placed directly in the product or in the external pouch.
The bag can be tied closed to prevent contamination during its lowering down the hole, allowing you to use dry product in wet holes and it won’t be washed out by dynamic water.
The KoolKap® Charge Bag prevents dead pressing in blast columns over 70 metres and can be placed precisely adjacent to hard bands in wet holes.
You can also suspend the charge at whatever depth you need to reduce powder factors in blown out holes or in pre-splits.
