The probability of a gas explosion in a high gas mine is not high, but a gas rush occurs in a low gas mine. In order to predict the gas hydrate pressure of mines in coastal areas, it is necessary to calculate the gas hydrate pressure of mines in coastal areas, and to propose a calculation method for the formation pressure of natural gas hydrates in coastal areas based on set pair analysis. The mine hydrate balance model in coastal areas was established by volume Kalman filter. The set pair analysis algorithm is used to optimize the distribution of mine gas hydrate formation pressure, and the quantitative calculation method is used to quantitatively control the mine gas hydrate formation pressure. The calculation of the pressure of gas hydrate formation in coastal areas has been realized. The simulation results show that the method can be used to calculate the formation pressure of mine gas hydrates in coastal areas, and it has good predictive performance and improves the prevention and prediction ability of mine gas disasters in coastal areas.
