It seems to me that its impossible to achieve rotation ONLY along the drill string axis as the inclination differs from 0. Surface collapse is typically a result of a significant overexcavation above the bore hole, which can be caused by large volumes of thin drilling fluid used at high velocities, incomplete filling of the annulus with drilling fluids for a large-diameter bore near the surface, or leaks in high- pressure pipes after installation, which erode the soil above the bore hole.
