Technology and practice of the roof-caving of hydraulic fracturing in a fully mechanized caving face

Year: 2021

Type: article

Abstract: A fracture expansion criterion of hydraulic fracturing was suggested to deal with the hard and stable roof control in coal mines. An experiment was designed for the roof control, and the reliability of model was verified. Four different types of fracturing holes and fracturing technology were designed in the setup room, and the hydraulic fracturing in the roof of a fully mechanized caving face was implemented.
