4.     METHOD OF STABILIZING THE BOREHOLES





               •    Drill Mud

                    •   The drill mud is pumped down the drill rod and exits through

                        the drill bit.


                    •   It lubricates the bit, cools it, and carries cuttings to the surface.
                        The mud also provides hydrostatic pressure to prevent collapse.


                    •   Advantages: Effective in various soil types, including hard

                        formations.

                    •   Limitations: Requires proper management and disposal of used

                        mud.
