Specific conditions of underground coal mines at great depth, such as high temperatures, high rates of methane inflow and natural ventilation pressure provide considerable challenges for
It identifies the major factors impacting the design of a ventilation system for the prevention of spontaneous heating/ fires in one of the deep underground coal mines of the
Our novel concept assumes placing the thermal energy storage (TES) system based on the use of solid storage material in the volume of the post-mining shaft forms a sealed air pressure
Intelligent ventilation is a highly integrated system, which should be different from tra- ditionalexpertsystemsbasedonknowledgesearchandneural network technology.
Energy storage is the key to solving the above problems. The present study focuses on the compressed air energy storage (CAES) system, which is one of the large-scale energy storage
The ventilation effect has a direct influence on the efficiency and security of the construction of an underground cavern group. Traditional forced ventilation schemes may be ineffective and result in
The solar - water thermal energy storage system investigated in this study consists of several subsystems, i.e. key components illustrated in the following Fig. 4, including solar collector, a
An engineering software to design the auxiliary fan and the ducting system was developed to optimize the auxiliary ventilation systems in mines and tunnels. Different duct material and
Ventilation in an underground coal mine is a key risk control. When the ventilation fan stops unintentionally or there is reduced performance there will be a change to the ventilation currents
