Latest Patents

Yabin Gao holds a patent for a method of performing combined drilling, flushing, and cutting operations on coal seams that have high gas content and are prone to bursts. This method is designed to relieve pressure and increase permeability when drilling through-seam boreholes to pre-drain gas belts in coal mine roadways. The patent outlines a pressure relief and permeation method that adjusts the water jet inlet pressure in different stages based on the drilling construction's position. During the drilling stage, low-pressure water flow is used for drilling, while medium-pressure water flow is employed for flushing. Upon withdrawing the drill, high-pressure water flow is utilized for slotting, effectively relieving pressure in a stepwise manner.
