The present invention (referring to all the holes in the ground, such as ground water, paper breaks, groundwater measuring ball) relates to ground water and geothermal resources, environmentally friendly drilling hole drilling apparatus and method for over the drilling effluent recycle injection, digging ball of soil drilling as it the pollution of the surrounding stream due to the drilling effluent by injecting material to the separated ground water to the drilling slurry and be mixed in the ground water in the drain water discharged from the drilling process selected from the ground by type within the excavated hole or other tricks ipgong are digging It made for the purpose of setting the environment so as to preserve prevented.
Underground water and environment-friendly drilling hole drilling apparatus for geothermal resources through the drilling effluent recycle injection according to the present invention, the drilling performed by rotating the drilling bit, wherein the drilling bit via at least one connecting rod, said connecting rod being connected to the drilling bit so that the drive means, is formed in the connecting rod chakjeong means 10 which is configured including an air compressor for injecting high-pressure air drilling a drilling hole in the ground and that; And groundwater screening chamber 20 to precipitate the slurry discharged from the drilling hole to ground and screened slurry; The underground water screened through the groundwater screening tank comprises a pressure-feeding means (30) for re-injection to the inside of the drilling hole, the pressure feeding means is press-feeding pump 31 for pumping the ground water the slurry is separated through the groundwater screening crude injection to connected to the force feed pump and supporting said pressure-feeding inlet tube as removably connected to the connecting rod of the pressure-feeding inlet tube 32, the chakjeong means for injecting ground water that is pressure-fed by the pressure feed pump inside the drilling hole It characterized in that it comprises a support tube.
