Traditionally, underground communications are laid in a trench way. Its necessary to dig out the upper fertile soil layer and green space. If the work is passing across the road, its also necessary Horizontal directional drilling (HDD method) is a way to lay various Horizontal directional drilling is often used where open cut installations are not feasible, such as road and river crossings. Using directional drilling techniques to guide a drill string along a bore path under obstacles such as rivers, lakes, railway crossings or highways, enables replacement of existing water lines, or installation of new ones, at a relatively rapid rate.

Directional Drilling

Directional Drilling Directional drilling offers benefits such as increased productivity and pay zone of the reservoir, decreased costs associated with the same amount of productivity (it may take one horizontal well to recover a substantial amount of hydrocarbons in a

Horizontal Directional Drilling (HDD) is not a new technology when it comes to the installation of pressure pipe systems for water distribution or sewage conveyance.Until recently, the installation process has typically been more expensive than traditional open-cut

Directional drilling is used to install conduits under obstacles such as roads, buildings, and wetlands. As demonstrated in this video, conduits such as water, sewer, fiber, electric, and gas can be installed under very busy intersections without disruption of traffic.

A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water.The oldest and most common kind of well is a water well, to access groundwater in underground aquifers.The well water is drawn up by a pump, or using containers, such as buckets, that are raised mechanically or by hand.

A hand-dug well may look like the nursery rhyme well in Jack and Jill—a deep hole surrounded by a stone wall. Most wells however, appear as a pipe, usually 5 to 25 centimeters (2 to 10 inches) in diameter, sticking up a short distance above the ground, typically less than 60 centimeters (2 feet).

Underground coal mines commonly employ horizontal drilling technique from the coal face and perpendicular to the face cleat to maximize gas drainage in front of mining. This technique is more efficient in draining gas compared to a vertical well, which has to be drilled for some vertical distance before reaching the coal bed.

Back in the 1960s, job sites for horizontal directional drilling were nowhere to be found. It wasn't until Martin Cherrington observed a gas line being installed using a hand-held air drill that the idea for HDD became more than just a suggestion but a possibility.

Drilling Epiroc offers state of the art drilling equipment for underground mining and tunneling. Our comprehensive range of rigs cover all your needs for production drills and face drilling rigs. Our drilling rigs offer a variety of feed lengths, positioning configurations, rock

Perseverance Drilling was formed in March 1996 to provide a cost effective, underground contract drilling service to the Australian mining industry. It was realised that production drilling often takes a back seat to development activities, thus the company was set up to initially specialise in underground production long hole drilling.

Chapter 12 Horizontal Directional Drilling 423 establishes the path of the drill rod ("drill-path") and subsequently the location of the PE pipe. Typically, the bore-head is tracked electronically so as to guide the hole to a pre-designed configuration. One of the key

Directional Drilling Horizontal Boring Directional drilling is a trenchless method of underground pipe installation. Horizontal boring machines drill a pilot hole which is able to enter and exit at predetermined locations and even change direction to avoid underground obstructions and preexisting lines.

Conventional underground mines in South Africa traditionally have narrow reef ore bodies, with a rail track infrastructure, use compressed air as an energy medium and drilling is by hand. The HPE drilling rigs for horizontal development and incline tunnel
