Horizontal drilling machines are specialized equipment used to create horizontal boreholes in the ground. They are commonly employed in the oil and gas industry to access resources located deep underground without disturbing the surface. This technique minimizes environmental impact and allows for efficient extraction of materials. These machines operate by using a rotating drill bit that cuts through soil and rock, while simultaneously installing a casing to support the borehole. Horizontal drilling is also used in other applications, such as installing utility lines and geothermal systems, making it a versatile tool in modern construction and resource extraction.
