  Numerical study on the dynamic response of coal mine seals …

  2023121 · Gas explosions in chemical production, mine mining and urban public tunnels are among the most frequently encountered and most consequential accidents [11], [12], [13]. In comparison, the intensity of methane explosions in coal mines is much higher than in other environments due to enclosed spaces and crowded equipment [8], [14].

  Structure of shock and detonation waves propagating in hybrid methane ...

  20231024 · Explosions of methane, coal dust suspensions, and methane–dust mixtures are considered to be the main types of explosions in mines [ 1, 2, 3 ]. To prevent the development of a catastrophe, it is proposed to quench the shock or detonation wave (DW) at the initial stage of its formation and propagation.

  Influence of airflow movement on methane migration in coal mine …

  2021121 · Abstract Spontaneous coal combustion was proved to cause methane accumulation and methane explosions in coal mine goafs. To avoid possible methane explosions, the empirical engineering measure, ventilation dilution, is proposed in coal mines though its disaster prevention mechanism has not been well understood. Through …
