Abstract In view of poor permeability of coal seam and soft coal quality in
China's coal mining area, a point hydraulic fracturing method suitable for the
occurrence characteristics of coal seam is put forward based on the characteristics
of coal seam hydraulic fracturing and the field practical experience of coal seam
hydraulic fracturing for many years. A theoretical and mathematical model of
hydraulic fracturing is established. Based on the large-scale finite element
software ABAQUS, numerical simulation of two dimensional and three
dimensional hydraulic fracturing is carried out, and the fracture propagation law
and its parameter sensitivity… More >
