In order to actively explore efficient means of gas control in mines, Jineng Group Zuoquan Panchengling Coal Industry makes full use of the ultra-high pressure hydraulic slit device unloading and permeation technology, and conducts a 30 d comparative investigation of the pumping and discharge effect in the mining face of the 150106 transportation downstream coal roadway, groping for an ultra-high pressure hydraulic slit unloading and permeation gas control scheme suitable for Panchengling Coal Industry, which significantly improved the efficiency of gas extraction. The gas extraction concentration increased by 1.9 times, the extraction flow increased by 1.35 times, and the time required to reach the standard was shortened by 60%, which effectively controlled the gas and ensured the safety of the mining.
