Morphological characteristics and permeability evolution of deep mine gas drainage boreholes

Morphological characteristics and permeability evolution of deep mine gas drainage boreholes

Structural coal has low permeability and high gas content. The increase of mining depth seriously restricts the safe mining of deep mines. Hydraulic flushing is the main means of gas extraction. The shape of the hydraulic flushing hole is an important basis to determine the pumping radius, which is...
