Abstract: Taking QYW-31 drilling in Qiyuan Coal Mine as the object, the drilling engineering of high fluid volume water sand
fracturing gas control technology for vertical surface wells was designed and studied. The implementation of this project can
effectively improve the state of stress concentration in the area affected by fracturing, reduce the coal seam gas content through
pre-pumping, reduce the risk of coal seam outburst, improve the mining speed, and ensure the safety of coal mining.

Key words: water sand fracturing; gas control; drilling
