Coal mine ventilation shaft energy storage system design diagram

How should a coal mine ventilation system be designed?

These systems should be designed to ensure that adequate amounts of ventilating and numerous split air reach each working area. Most underground coal mines in India employ an exhaust (i.e. negative pressure) ventilation system.

What is a coal mine ventilation survey?

In order to gain an understanding of the complex networks incorporated in the system, a coal mine ventilation survey is required. The information obtained from this survey is used to determine the most efficient techniques to accomplish any proposed improvements.

How to determine the effectiveness of ventilation design of underground mine?

Determine the effectiveness of ventilation design of the underground mine by proper monitoring. In case of incorrect entries or improper data details, it indicates the airway number along with the type of problem existed. Helps in monitoring of leakage in the goaf side due to sudden change of air quantity.

What is a mine ventilation design?

Recently, research on mine ventilation has focused on analytical methodology [4, 5] and optimization [6, 7]. Mine ventilation design includes estimates of air quantity required by each branch, ventilation network analysis, and the development of various measures to satisfy such requirements.

What is the control model of a mine ventilation network?

The control model of a mine ventilation network is based on Kirchhoff’s current and voltage laws and fluid dynamic equations of individual branches. The branches are modeled using lumped parameter approximations of incompressible Navier–Stokes equations . The airways are treated as circuits .

How does mining environment affect ventilation system performance?

It is well-known that mining environments are dynamic and changing very rapidly as mining excavation continues using road header/continuous miner progressing. In essence, changes in mine environment will also change the ventilation system performance, e.g., ventilation area, methane flow rate, dust generated and so forth.
