DynoTex
In many kinds of blasting work, it is important for the blast to break in such a way that the remaining rock surface incurs the least possible damage. To help achieve this, Orica Mining Services supplies a series of tube charges of different dimensions and strengths, based on nitroglycolbearing powder formula.
The Orica Mining Services series of tube charges is registered under the Dynotex trademark. The number after the productname indicates the strength of the formula, with 1 indicating the highest strength and 4 the weakest strength. (See “Energy content”.) Since Dynotex® tube charges have limited resistance to water, their use is limited to relatively dry drill holes only. Dynotex® tube charges should be stored in dry conditions, and storage time should not exceed 2 years.
Dynotex® tube charges were developed for contour blasting. However, they are also suitable for blasting in densely built-up areas, where the risk of groundvibration calls for reduced and controlled charges in the drill holes.
Another application, especially for the weaker tube charges,is dimensional-stone blasting. The tube charges are delivered with locking sleeves (in the case of Ø 17 mm tube charges) or jointing sleeves (in the case of Ø 22, 25 and 32 mm tube charges).
