The drilling process itself involves a technique known as 'circulation.' A drilling fluid, commonly referred to as 'mud,' is continuously pumped down the drill string, through the bit, and back up the annulus between the drill string and the walls of the hole. This fluid serves multiple purposes it cools and lubricates the bit, carries cuttings to the surface, stabilizes the borehole, and provides hydrostatic pressure to prevent underground fluids from entering.

2.Conductive fiberglass grating
Fibergalss grating itself is an insulator, non conductive, non thermal conductivity, but in some specific places, it also has a conductive requirements. The detailed operation method is to eliminate the damage of static charge inoculation in the rock layer with a thickness of about 3~5mm. The conductive grating also has same characteristics  with traditional glass steel grille ,such as corrosion resistance, flame retardant,anti strike, skid resistance, light weight and practical in refinery and armaments manufacturing factory, high-tech industry, computer room, chemical plants, dry areas and underground mining operations.
