Ventsim - 3D Mine Ventilation Simulation Software 2½ day training course

Description

Mine Safety

Complete custom-designed ventilation, cooling and heating systems for underground mining applications. Low carbon fuel systems and mine water treatment.

Ensuring safe and efficient mine operations

Howden's fan technology provides highly efficient ventilation for safe and underground mining. Heating and cooling solutions maintain an effective working environment and Ventsim software optimises system control. Chart's fuelling and water technology adds to onsite environmental management.

Underground ventilation

Our fans are relied upon to maintain safe and comfortable conditions for workers within underground mines. Our fans draw large volumes of air through the ventilation system as well as extract waste air and harmful gases from protected spaces.

With a wide range of fan technology, we provide fans for main air or auxiliary air supply. With longstanding experience in ventilation, we offer our expertise to mine operators through ventilation system consultancy and our leading Ventsim software aids designers to understand and develop the best systems attuned to the conditions of each mine.

We have a full project delivery capability which includes the ability to offer turnkey ventilation systems incorporating fans, auxiliary equipment, electrical systems with installation and commissioning.

We can help you optimize operation through Ventsim CONTROL, which adjusts fans and dampers based on gas or air flow sensors. This is an automated solution scalable to Ventilation-On-Demand giving increased safety and operation control and significant energy savings.

Aim: to maintain productive and safe working areas underground by delivering optimised air flows efficiently and reliably.

Mine air heating and cooling

With mines located in some of the world’s most extreme climates, temperature control is a vital part of successful operation. This is also impacted by the increasing depth underground mine are reaching, necessitating cooling for safe and productive working environments.

Howden’s cooling and heating technology integrates seamlessly with the whole ventilation system.

A wide range of heaters and cooling systems are available to condition the air for supply within the mine, meaning there is great flexibility in regard to required capacity and other factors such as potential fuel sources, emissions, site configurations and operational efficiencies.

Aim: to provide controlled levels temperature within the mine ventilation system and enable continuous productive and safe working areas.

Mine heaters – direct and indirect-fired heaters, electric heaters, thermal heat recovery

Water Treatment

Responsible mining involves ensuring wastewater quality standards are maintained to protect the local environment and be compliant with regulations.

Chart has specialist water treatment and reuse technology that enables mines to remove a wide variety of contaminants from mine wastewater.

Aim: to treat wastewater to acceptable standards required for re-use or safe discharge.

Fuel Systems

Increased environmental pressure is moving mine operators towards lower carbon energy solutions for off-grid sites.

Chart can provide design and supply of complete fuel storage and distribution systems. This includes insulated tanks for liquid storage (LNG/Hydrogen) and regasification systems for supply to gas based power generation units.

Using gas to fuel vehicles reduces greenhouse gas emissions by up to 30% versus conventional liquid fuels. Chart is the world's leading supplier of LNG vehicle fuel systems and our core technologies are applied also to hydrogen powered vehicles.

The fuel system is available for mine haul trucks as a retrofit for existing trucks – conversion for LNG/LH2 or dual fuel - or for integration into new haul trucks.

Aim: to lower mining operations carbon emissions by enabling gas based energy usage.

Fans

Our product range covers axial, centrifugal and mixed flow fans in a vast variety of configurations for both underground and surface fan applications. They provide versatility, economic advantages, low noise characteristics and outstanding aerodynamic performance.

Cost-effective, low-maintenance solution in providing high efficiency over a wide operating range for applications
Suitable for clean to moderately dirty air handling large air volumes
Blade pitch control can be either manually adjustable at rest or auto-variable pitch
Highest efficiencies possible
Suitable for higher pressure, lower flow operation with a wide range of design flexibility
Most common solution for primary ventilation applications
Custom engineered fans to precisely meet the application requirements of the most demanding specifications
Robust fan design and suitable for dirty and corrosive air in exhaust Return Air Raises (RAR)
Lowest noise footprint
Cost-effective alternative to an axial flow fan in situations where dust loads are of concern
The mixed flow impeller is more robust and not susceptible to performance deterioration due to wear of the blades
Combines the benefits of Axial & Centrifugal Fans, being very robust and at the same time able to handle large air volumes
Designed to give the highest fan output at low power consumption, providing high efficiencies across a broad operating range
Aerofoil blade design with efficiencies of over 85% possible
Adjustable pitch blades maximise operational envelope
Flexible and modular design - commonality of parts and flexibility on the arrangement, components and number of stages
Improve or augment the ventilation in a segment of the mine
May also be used to support flow requirements in particular locations of the mine where vertical raisers are not possible
Operating Range 250m3/sec, 5kPa, 1500kW

Mine Heaters

With our vast range of mine heating solutions, Howden sets the standard for heating. Our heaters are capable of burning everything from natural gas and propane to waste oil.

Premium efficiency, serviceability, and low emissions are key to the design of a mine shaft heating system. We ensure every heater is designed to operate safely and effectively in the toughest environments.
