Directional drilling has several key advantages over traditional non-directional drilling techniques when dewatering strata in advance of mining. Holes can be maintained within a targeted strata layer or steered to intercept water-bearing features at intentional angles that maximize hydraulic connectivity and drainage. In addition, sidetracking capabilities allow for maximum coverage from fewer borehole collars and setup locations. More novel applications include vertical well intercepts to drain water collected in horizontal laterals to a production well.
