Hydraulic Fracturing and Anti-reflection Test in Guizhou Yushe Coal Mine No.11014 Mining Face
In view of the fact that there is a blank belt in the 11014 mining face of Yusha Coal Mine in Guizhou,which is not controlled by pre-drilling,the hydraulic fracturing and anti-pressure technology is used to carry out gas drainage in the 11014 mining face.Field tests were carried out by designing a reasonable hydraulic fracturing borehole and selecting suitable fracturing equipment.After the implementation of this technology,the single-hole extraction concentration of the 11014 mining surface is more than 30%,and the pure flow rate is increased by 17%compared with the fracturing.This effectively solves the difficult problem of eliminating the quasi-reaching standard and it ensures the safe and efficient mining of coal mines.
