Auto-orientation Scheme of Hydraulic Correction for Nearly Horizontal Hole and Its Hardware Implementatio
For actual demand of nearly horizontal hole drilling of coal seam methane, the paper proposed a scheme of auto-orientation of jet stream of hydraulic correction combining with hydraulic correction technology and designed a correction system based on the scheme. The correction system takes a single-c...
