Field investigation of multi-stage pulse hydraulic fracturing for improving permeability of coal seam in directional long borehole in underground coal mines

Directional long borehole has been promoted in underground coal mines. However, the hydraulic fracturing technology based on directional long borehole in underground coal mines is still in the initial stage. The uneven fracture distribution and small number of fractures in the conventional hydraulic...
