Mine ventilation is defined as a combined system of shafting, ducting and a well-designed combination of fans, mine ventilation is a basic need of mining industries,
It is required for providing adequate oxygen for the workforce and to dilute and exhaust dangerous gasses in the underground mine, it is also required to take a smoke of machine equipment out because many of machine in underground mine operates on fossil fuel.
Without proper ventilation in underground mines many kinds of health problems suffered by the human resource, efficiency of working reduced, and frequency of accident increase.
Due to these serious issue mine ventilation considered very important and it is governed very strict laws in most of the country.
Considering the above point in mind MAYA energy-efficient mine ventilation fan has set the standard for high reliability and low maintenance since its introduction. Our indigenous fan engineering know-how is utilized so that our fan, you select today provides the broadest range of configurations and the highest capacities available in a mine ventilation fan.
For decades, Maya Fan has been a leading producer of fans for the fulfilment of the varying requirement of this industry. The Maya mine ventilation fan takes advantage of this experience by bringing it down to energy consumption. And also provide a special low noise fan series, which brings down noise as low as 10 dB less compare to conventional mine ventilation fans.
For performance that exceeds specifications on a tight budget, the Maya Fiberglass mine ventilation fan incorporates field-proven, industrial-quality fans. You get the unsurpassed integrity, performance, and reliability you'd expect… at a price that may surprise you.
These fans are categories as - Main mine ventilation fans, mine ventilation booster fan and auxiliary mine ventilation fans.
AT Maya Fan We never force fit our standard existing fans, but remain responsive to input design data and develop new product as and when it required
Once the final fan design concluded, it is handed over to the production team for preparation of tooling. To final launch this product
Mine Ventilation Fans are mainly categories as main fan or surface fan, booster fans, and auxiliary mine ventilation fans. Below are the detail of these categories fans...
A mine ventilation booster fan is a primary fan that is in series with another primary fan. Without the booster fan operation, the total mine airflow will fall significantly. Booster fans are typically installed as mine develops and primary fan no longer has the pressure or flow capability to service increased resistance of operation. In this sense, booster fan operates as an integral and “symbiotic” unit with original primary fan to provide sufficient total airflow for mine.
Mine booster fans are technically main fans which are installed underground to maintain required airflow by overcoming the mine resistance. Booster mine ventilation fans can reduce pressure of main fan and decrease system leakage and total required air power.
A mines booster fan is an underground ventilation device installed in the main airstream (intake or return) to handle quantity of air circulated by one or more working districts. It is installed to operate in series with a main fan and boost air pressure of ventilation air passing through it.
Provision of additional air quality at strategic locations within the mine and separate from long wall split.
Key Feature of Maya Mining booster fans -
Maya High efficient airfoil blade design, optimization of twist cord and cross section provide maximum efficiency. Involvement of most advance composite material reduce turbulence and produce smooth linear flow of air which further reduce energy wastage significantly thus increase overall efficiency of mine ventilation fans.
We have also eliminate one of major cause for power wastage in fan which is very often phenomenon i.e. wrong selection of fan for the duty point or choosing over size fan for a duty point. Due to this reason more than 50% fan in the industry operate on lower efficiency thus unnecessary wastage of power observed. We eliminate this by offering final selection of fan throe our designer. Who chose optimum solution for the given duty point of mine data.
By application of latest airfoil and combination of different material for different parts compare to any conventional mine ventilation fan maya fans are relatively silent when compared for same duty point under same operating conduction.
Whereas for special requirement of extra silent fan we have developed a full series of low noise mine fans which can reduce sound pressure level as low as 10 dba compare to conventional fans. in general we are having habit to design fan on low tip speed and as fan sound power is directional depends on tip speed therefore maya fans remain relatively silent.
Maya mine ventilation fans is manufactured and assembled from corrosion-resistant materials i.e. Fiberglass and hot-dip galvanized construction which meets the corrosion resistance and equipment life requirements of your most demanding heavy industrial applications while still delivering an outstanding value. Also available with Series 300 stainless steel is an optional upgrade to the fans metallic component and includes a 5-year limited warranty. Maya mining Fans are manufactured in ISO-2015 certified facilities, attesting to our commitment to comprehensive quality processes and systems.
Note – For special duties fans and working conduction we do also manufacturer mine ventilation fan fans from high grade special material which include higher grade of Epoxy and various grade of aluminium and Stainless steel.
Fan is a constant flow machine and therefore for varying need of flow capacity for equipment to keep maintaining its perform despite critical variation in weather Maya mine ventilation fans are design for very broad range of operation our fans are having good amount of reserve margin for both airflow and resistance/pressure therefore these fans are capable of maintaining mine ventilation performance throughout the year in all type of seasons.
Maya FRP mine ventilation fan are made of high quality material and robust in design and also because of low operating tip speed overall system life increase it also reduce chance of failure and reduce impact in exceptional case of accident.
Unlike painted fan we do provide permanent coating of gel coat which remain integral part of fan blade body and do not get separated due to erosion.
All above advantage made Maya mine ventilation fan almost free from maintenance thus do not required any additional down time and can be maintained along with other fan system component and need no down time other then system component thus we call it zero maintenance mine ventilation fans.
Here is the list of Maya mine fan component with a there brief detailing
Blade – Maya mine ventilation fan blade is made of latest airfoil similar to that of airplane wing we do choose most advanced airfoil possible for the fan to provide maximum efficiency by this only we have achieved superior performance which is far ahead in the mine ventilation fan industries, our blade is very robust in construction and designed for 7-10 times of operating load we also provide superior wear resistance material to maintain surface stability for long period of time which prevent efficiency deterioration. recently we have developed a special series in mining fans in which we are providing state of the art fans in fiber reinforce plastic we are using this superior epoxy material for the blade tip speed of up to 22000 FPM
This FRP material is having some of the very charismatic property it is very much possible to produce any complicated shape with ease thus provide economical solution some of its special features are and listed below -
H ub/Boss –used in mine ventilation fans are of heavy in construction in this we are using heavy thickness mild steel plate, cast iron or Aluminum clamp and stainless steel hardware to provide long life we are coating all mild steel part with heavy thickness of zinc.
Note - Optionally we also provide customize hub/Boss on special demand of the customer, like caste hub boss, Spider Type Fabricated hub, etc.
TLTaper Locking – in most of our mine ventilation fan hub we preferred to have a taper locking arrangement and this is provided with several types of different locking arrangements which are proven in the field these taper lockings are mostly made of Cast iron or stainless steel.
Fairing inlet and outlet - these are inbuilt component in mine ventilation fan, as in mining fan pressure remain high and air travel at very velocity therefore even small turbulence harness unnecessary energy so it is very must to have smooth airflow throughout the fan system and well design and construed inlet-outlet fairing contribute significantly, we at Maya fan make these fairing in composite material to provide smooth finish which helps to keep laminar uninterrupted flow through the fan system
Inlet guide van - are used to guide inlet air in such a way that it will inter in impeller at a particular angle so that it will have minimum losses for changing the direction of air under fan impeller.
Outlet guide van - are used to guide exit air in such a way that it will remain linear to the system with minimum turbulence in it. which will prevent eddies generation and minimize friction of air with the fan casing surface.
Silencer in mining fan - are used to minimize fan sound to a desired acceptable level. these mine ventilation fan silencers are designed to match with the shape of a fan and to have minimum pressure drop in it.
Fabrication of mine ventilation fan - mining fan is having a large component of fabrication starting from its main body to diffuser and many other parts these are required to have a good control there for it is manufactured under closed control of ISO system and are maintained as per Section IX, ASME
