Minvent - Inflatable Underground Mining Ventilation and Sealing Solutions

Minvent Solutions is a wholly owned and operated Australian Company. Our primary focus now is in designing, manufacturing and supplying safe, innovative, cost effective and efficient products and solutions.

Minvent Solutions is the industry leader in providing safe, cost-effective, inflatable and re-usable products that cover multiple applications. Some of these products have evolved into unique and unrivalled levels of effectiveness.

For example: the Ventstop that began its modest existence as a ventilation control is now a multi-purpose inflatable that is available in many formats and shapes to provide application options such as, emergency seals, inflatable form work, overhead protection systems, bin liners, shaft sealing systems and much more.

Our latest additions are the Bin Bag, Void Plug and Shaft Plug.

INFLATABLE VENTILATION AND SEALING UNITS

All these units have been designed to provide protection to personnel and infrastructure during construction and maintenance, i.e. replacement or repairs to wear plates, chutes and impact beds, bleeding of gases / built-up pressure inside the void and a facility for fire fighting through the central sleeve.

Each bin bag and shaft plug is job specific and may be lowered or raised into the void and inflated, this process can take as little as a couple of hours. Once the unit is inflated inside it functions as an overhead protection system and or plug preventing freefall of materials from above or within the bin. It also displaces gasses and fumes that may have built up inside the bin or shaft.

VENTSTOP VENTILATION CONTROL UNIT (VCU) STOPPING

The Ventstop ventilation control unit is designed to specific applications:

• Any size or shape
• Portable and re-usable
• Available in standard or FRAS (Fire Retardant Anti-Static) fabrics
• Continuous air trickle or bottle feed
• Available with through sleeves
• Safe, cost effective and efficient

PASSLINE OVERHEAD PROTECTION UNIT (OPU) SYSTEM

The Passline overhead protection system has been designed to enhance the safe working parameters of personnel and infrastructure.

• Pre-pentice or pentice alternative
• Modular, portable and re-usable
• Suitable for most vertical, dumped or inclined shafts and raise bore holes
• Available in most diameters and lengths

SHAFT PLUG VOID SEALING SYSTEM (VSS)

The Shaft Plug Void Sealing System (VSS) has been specifically designed to provide the user with a product that provides emergency and short-term sealing of an intake or exhaust shaft.

This product provides you with an emergency seal of the shaft when the permanent cover has been compromised or simply needs replacing or other infrastructure is to be connected. It may also be used as a pre-cover or shaft pentice. The shaft plug is available with or without a venting tube, in standard or FRAS fabrics and is re-usable.

The Shaft Plug can be installed remotely using a long boom crane, this makes it the safest, most efficient and cost-effective alternative for your shaft collar construction or maintenance requirements.

Venting tubes are designed to specific requirements and are correlated with Shaft Plug design to ensure that build up of air/gas pressure from the underground source on the shaft plug can be safely and efficiently drained away.

The gas/air is removed from the area via a lay flat ducting tube and may be connected to a flow measuring and non return valve or fusible link shutoff system, and into an EOL flame arrestor.

The Shaft Plug is also suitable for horizontal or inclined application and can be designed to specific in-situ requirements.

Need ventilation products or over-head protection systems, due for a shut down and need to provide a safe work environment for your bin maintenance? Want to give your emergency department the latest and safest options available.

OVERHEAD PROTECTION SYSTEMS

Overhead Protection Systems (OPS) are without a doubt, the safest, most efficient and cost effective form of protection for personnel and infrastructure available today.

Specifically designed to suit onsite requirements, in roasters, furnaces, kilns, reaction shafts, scrubber vessels, silos just to name a few. These inflatable, re-usable systems can be operational in a matter of hours eliminating the requirement to install extensive scaffolding, nets and covers.

Our systems eliminate the risk involved when personnel are required to go into an area where there is a likelihood of debris striking them from above and the possibility of major and /or fatal accidents resulting as a consequence of that exposure.

The systems are designed to apply positive pressure on all surfaces within the subject area, thus preventing free fall of materials and completely eliminating the hazard.

Minvent Solutions' patented OPS is available in single or multiple units can be designed to fit most application requirements, is available with a comprehensive Audible/Visual Alarm system with at point of activity monitoring.

Systems are also available with positive or negative pressure venting sleeves to remove dust, gasses and hot air in the working area below the OPS.
