involves enlarging the initial hole to the desired diameter in order to accommodate a pipeline of the required diameter. as the pilot hole is being drilled, bentonite drilling mud is pumped down the aperture in the centre of the drilling rods. jets of bentonite mix penetrating through nozzles cut the soil

and facilitate the removal of soil particles by washing them to the surface where they settle out in a reception pit. the direction of drilling is guided by turning the head down, up, right or left, as required. the drilling of the pilot hole is monitored by a specially designed survey system. a sensor...

cosmic rays on oxygen and nitrogen . this beryllium (being soluble in water at ph below ) readily dissolves in rainwater (which generally has a ph less than five) and is transported to the earth's surface. as this water quickly becomes more alkaline, be drops out of solution and accumulates at the soil

surface. given its half-life of million years, be has a long residence time before it decays to b (an isotope of boron ). the isotope be and its daughter products have therefore been used to examine soil erosion, soil formation from regolith , and the development of lateritic soils . it has also been...
