The "Dixon Valve" is a device that is used to facilitate the
bottom loading of slurries in upholes. The design of the valve is simple,
easy to use and is cost effective to manufacture. The specifications have
been designed to accommodate diameter variances of designated blast hole
sizes due to - 1) drill bit wear 2) rock structure 3) wandering drill bits
4) and other variables.
- Charging of the blast hole from the bottom means that a solid column
of explosive product fills the blast hole. This eliminates the possibility
of the product slumping and decoupling.
- The loading procedure is identical, irrespective of whether the blast
holes are wet or dry.
- Variances in the designated hole sizes are easily accommodated.
Prototypes have been successfully tested in the field. Manufacturing
of this product is expected to commence shortly.
"Blast Hole Dewatering System"
The Blast Hole Dewatering System is designed to remove perch water from
blast holes prior to charging.
This product is currently being field tested.
