Fully mechanized caving face gas control method

The invention relates to the technical field of coal mining treatment, in particular to a fully-mechanized caving face gas treatment method which comprises a ventilation pipe, a valve, a connecting device, a height adjusting device, a direction adjusting device and a fully-mechanized caving face, a fully-mechanized caving face gas treatment device is fixed in the fully-mechanized caving face, and at the moment, the ventilation pipe is fixed in the fully-mechanized caving face; then a filter plate arranged on the connecting device is placed at a proper position on a supporting ring arranged in the connecting pipe, then a positioning pipe is moved upwards to enable the positioning device to penetrate through a through hole formed in a ring body, at the moment, a limiting ring arranged at the top of the filter plate moves to the outer side of the connecting pipe, meanwhile, the filter plate is attached to the connecting pipe, and then the positioning pipe is rotated; according to the filtering device, through th
