Rise Mining Developments Components and Simulation Services for Underground Mines
Rise Mining Developments performs research and development (R&D) for hard rock underground mining applications.
The company operates through three trading names, namely Underground Stemming, Bleeding Bit and DD Grout Plugs.
Underground Stemming provides stemming plugs for uphole blast holes, Bleeding Bit is researching the use of virtual reality (VR) mine simulations, and DD Grout Plugs supplies high-pressure diamond drilling plugs globally for underground mining.
Stemming plugs for overhead blast holes in underground mines
Underground Stemming designs and manufactures unique stemming plugs for uphole blast holes. They can be pushed up any distance, lockout on retraction of the charge hose, and are removable in the event of a misfire.
Stemming has been shown to increase blast efficiency and fragmentation, as well as reduce or prevent blast damage around the firing location and reduce the amount of explosives.
Traditionally, overhead blast holes in underground mines are not stemmed due to the challenge of stemming against gravity. The lack of stemming can result in rifling out of the collar of the hole, brow damage in longhole stopes, poor containment and fragmentation, and inefficient use of explosives.
Stemming of overhead blast holes allows the drill and blast engineer to refine the blast design to significantly improve blasting outcomes and reduce the overall cost.
The Pineapple stemming plug is an easy-to-use product, which allows stemming against gravity in upholes.
It can be used for a wide range of applications, including:
- Ore drive ground support protection from rifling with slashing shots
- Keeping the brow square and accessible
- Undercuts for forming draw points in block cave development
- Firing orebodies from a footwall drive
Bleeding Bit provides mine duplication and simulations in virtual reality (VR).
Practical uses for mine duplication in VR are many and varied. For instance, these simulations may be used to review designs prior to being executed, greenfields (new mines) or brownfields (extending existing mines).
Equipment can be demonstrated in existing mines prior to being purchased. Remote mines in other continents may be inspected from the mining company’s head office, and those mines can showcase the mining operations to non-mining personnel.
Bleeding Bit’s VR capabilities allow mining operations to record ground conditions so that they can be accessed in the future for geotechnical control.
Combining mine duplication with live data will allow real-time monitoring in the virtual mine.
Diamond drilling plugs for underground applications
DD Grout Plugs provides pressure and load-rated diamond drilling plugs for underground mining.
These plugs are used for high-pressure water control, high-pressure grouting, and protection from rifling from blasting in the vicinity of open diamond drill holes.
The simple patent-pending design provides the highest pressure and load ratings available to diamond drillers, rated to 1,000psi (69bar) at a factor of safety of 2:1.
These plugs are supplied worldwide from our manufacturing base in Perth, Western Australia.
Products and Services
Mine duplication in Virtual Reality.
DD Grout Plugs – Terra-Barb
The Terra-Barb was developed as a quick and more cost-effective solution for blocking off rifling from potential diamond drill intersections with underground blasting.
DD Grout Plugs – Hydra-Barb
The Hydra-Barb is rated to 1,000 psi (69 Bar) with a factor of safety of 2:1.
DD Grout Plugs – Grouter and Grouter Mk3
The Grouter was developed based on the Hydra Barb design but with an internal check valve for high-pressure grouting through the plug.
Pineapple Underground Stemming Plug
The plug is made out of glass-reinforced nylon for strength.
