Manual sampling during the closure of the mine fire area is usually accompanied by differential pressure measurements inside and outside the confinement wall. The only way to help rescuers determine the state of development of the fire zone is to obtain gas samples that reflect the internal composition of the fire zone. Therefore, it is necessary to study and analyse the reasons for the fluctuation of the differential pressure inside and outside the confinement wall.
