MINTECH is a wholly Australian owned company and has been operating successfully for over 17 years supplying blasting accessories world-wide to the Mining, Quarrying and Civil Construction Industries. MINTECH products provide the ideal tools to achieve real Cost Effective Blasting.
|MINTECH INVENTED:-||Expanding Foam Borehole Plugs|
|Non Aerosol (Chemical) Gasbags|
|Stemkones (for Drilled Blasthole Protection)|
|Borehole Depth Sounders|
|Stemliner System - (A Safe and Reliable Blasthole Lining System)|
MINTECH'S core business is the patented development and manufacture of Aerosol and Non-Aerosol Gasbags for a variety of blasting applications. MINTECH developed, in conjunction with mining companies and regulatory authorities, their safe and practical applications for use. We also developed gasbags for use in hazardous underground environments. Consequently MINTECH gasbags comply with all the federal and state codes with regard to manufacture, storage, transport, environmental aspects and usage. Additionally MINTECH'S aerosol propellant conforms with International Agreements covering environment protection.
MINTECH'S Stemkones provide for drilled blasthole protection by preventing the unwanted backfilling of blastholes between the drilling and loading cycles.
MINTECH'S Stemliners enable the use of ANFO instead of costly water-proof explosives in dewaterable blastholes.
MINTECH'S Borehole Sounders sonically measure and record blasthole depths, to within 0.5m, thus minimising the need for time consuming manual depth measurements.
MINTECH is at the front line in striving to meet customer requirements and developing our products according to customer needs. MINTECH'S philosophy is to supply products and services that meet the highest consistent quality criteria. These quality criteria are backed up by MINTECH'S accreditation according to ISO 9001 - a standard by which the majority of our customers operate and which was demanded of us by the mining industry. MINTECH also has available qualified technical and support staff who are thoroughly conversant with the mining, quarrying, explosives and plastics industries.
MINTECH has established joint ventures in the UK, USA, South Africa, India and Chile. Accordingly we have access to a wide range of drilling and blasting applications that have provided welcome solutions in other difficult situations.
MINTECH'S aim is to continually maintain the high standards achieved, develop products according to customer special applications and ensure that all MINTECH products meet or exceed the specified standards and legal requirements of the mining and associated industries.
|Sealing off Nuisance Water|
|Mintech conceived and developed the Gasbag
to assist miners simplify and improve their drill and blast operations. The
Gasbag is a self inflating, high-strength balloon capable of locking
off in a borehole and bearing heavy loads for long periods of time.
Initially the product's main use was to seal off nuisance water in the borehole to allow maximisation of ANFO in preference to water resistant explosives.
|Top Column Air Decks|
|Top column air decks are suitable for most mining situations particularly in weak to medium strength materials where fragmentation in the stemming zone is required without gross movement. A 25% - 40% reduction in powder factor is common.|
|Mid Column Air Decks|
|Mid column air decks are recommended for harder materials or where significant movement is required. The air deck/charge ratio is lower than that used in top column air deck configurations. A higher level of fragmentation than either top or bottom column air decks results. 20% reductions in powder factor are common.|
|Previously a cumbersome operation due to the difficulty of distributing explosives throughout the borehole. Air decking using Gasbags has made this a simple procedure. Originally used for final excavation limits but now in regular use in multirow shots to produce clean, stable high walls.|
|Totally non hazardous||No storage, transport or handling restrictions|
|Lightweight Easy to handle||No aerosols or compressed air|
|The design loading can continue regardless of blasthole water levlels and dewatering equipment|
|May be located in the blasthole at any depth of water|
|Not affected by climatic extremes|
