A Discussion on Coalmine Shaft Pilot Hole Construction Techniques

The paper introduced characteris tics and technical, quality requirements of the shaft pilot hole in coalmines. Put forw ard technical measures based on engineerin g object lessons in days gone by, in allusio n to engineering technical nodi such as cor ing, hole deviation controls, pumping opera tion as well as flush fluid selection and ma intenance etc those are key links to affect quality and construction time limit. That c an be used for high quality and high efficie ncy construction references in projects be long to the same kind.
