Structural Optimization of Slotting Nozzle Used to Improve Coal-Seam Permeability
Slotting directional hydraulic fracturing is a new method for improving permeability of a coal seam in underground coal mines that can solve problems related to non-uniform permeability enhancement in the seam. A slotting nozzle is the key to this technology: its performance determines the length an...
