Drill pipe is added behind the reamer or hole opener so that there is always drill pipe in the borehole. The back reamer is pulled back while rotating the drill pipe to enlarge the borehole with as many consecutive passes as are needed. Upon reaching the exit point, the drill bit is detached and the end of the drill pipe is attached to a back reamer or hole opener (for rock), if the borehole must be enlarged. Drilling fluid (mud) is classified as non-toxic and can be disposed of accordingly. As drilling fluid is pumped down the hole the cuttings are carried back out to the surface where they are either allowed to settle out in a pit or removed mechanically in a mud cleaning system. In softer soils the jet of fluid cuts through the soil, with the cuttings suspended in the drilling fluid. Directional drilling fluid is generally a mixture of bentonite clay and water, with additives used to improve borehole performance. Air & foam machines are used for drilling in rock. Most directional boring machines use drilling fluid while a few machines are designed to use either air or air and foam.
