“…Fig 8 shows the simulation results of the oxygen concentrations in the goaf. The oxygen concentration method is used to divide the risk area for spontaneous combustible residual coal in the goaf [27]. Fig 8 shows that the range 0~33 m from the working face is the heat dissipation zone with an oxygen concentration greater than 18%.…”

“…Automated ventilation system adjustment software has been developed by monitoring the air volume of the minimum remainder branch in the network, and all air volumes of the branches in the network can be obtained by inverse calculation of associated branches [ 32 ]. Song et al [ 33 ] proposed a method for determining the changing trend of gas concentration in the goaf. Lyu et al [ 34 ] proposed a gas concentration prediction method based on the ARMA model, the CHAOS model, and the encoder–decoder model (single-sensor and multisensor).…”

“…In recent years, researchers have found that the gas concentration generally rises abnormally before incidents of coal mine gas explosions [ 5 ]. Therefore, in order to predict gas concentration accurately and prevent gas accidents effectively, researchers have proposed some gas prediction methods.…”
