Drilling holes might sound pretty straightforward, but once you get down to business it becomes a high-tech form of art. No need to worry, though! Robit Plc is here for you, whether you’re mining, quarrying, constructing or stabilizing ground to find a sure footing for your work.


Forepoling

Broken rock is no obstacle for tunneling when you are using Robit® Casing System. Forepoling, also known as tube umbrella, is an application used to strengthen tunnel roof in broken rock conditions. Drilling system consists of casing tubes which are drilled through the overburden as an umbrella and filled with grouting. Robit® Casing System allows easy driving of the casing tubes into the ground with low torque demand.

Robit® Casing Systems mostly used in forepoling are RoX+ 88,9/8, RoX 114,3/10, and RoX 139,7/10.

Piling, Micropiling and Underpinning

During decades and centuries of urbanization, the best available ground for construction has often been populated or otherwise utilized already. Softer ground conditions require a stabilizing technique before construction. The technique is to drill casing tubes through the overburden to the solid bedrock and fill them with concrete.

Drilled piles made with Robit® Casing Systems have significant advantage compared with other piling methods and systems: Fast drilling with maximum straightness of the hole, reliability to reach the targeted depth, and extreme simplicity to use.

Robit® Casing Systems mostly used in piling are DTH-RoX+ for permanent casing and DTH-RoX MU for temporary casing.

Water and thermal well drilling

Casing drilling is used in making water and thermal wells in broken overburden conditions. Robit® Casing Systems allow easy driving of the casing tubes into the ground with relatively low torque demand. The casing is left in the ground as a protection pipe of the water or thermal well.

Robit® Casing System mostly used in water and thermal well drilling is DTH-RoX+(+).

Anchoring

Anchoring is a method where walls with masses of overburden are anchored to the solid rock. To start, casing tubes are driven through the overburden. After anchoring the drilling can proceed with a normal drill bit. After drilling, a steel cable is inserted to the bottom of the hole and the hole is filled with grouting.

New Robit® Non-Stop Casing System is perfect for anchoring.

Drifting and Tunnelling

Underground mining and construction require both drilling to excavate and to support the rock. In drifting and bolting the diameter of drill bits used is typically 33-60 mm.

Construction

Drilling and blasting is an age-old method of rock excavation and is still one of the most used worldwide. Robit supplies tools from underground to surface applications, for tunnels, roads and for dams and much more.

Horizontal drilling

Drilling is often not about how deep you can go, but how far you go. Horizontal drilling is used to lead water, sewage, or cable pipes under roads, rivers, and buildings. There is no need block roads or ruin with extensive digs to the surface. Instead, horizontal holes can be drilled with Robit® Casing System without harming the surroundings.

Robit® Casing Systems typically used in horizontal drilling are large diameter tools such as DTH-RoX HZ 406,4/12,7.

Site investigation

Site investigation is used to evaluate the site and its suitability for proposed development. A casing tube is driven down to the selected depth and a sample is taken with a coring tool. Robit® Casing System enables more accurate drilling to reach the targeted depth.

Robit® Casing System typically used in site investigation is DTH-RoX MU when the holes drilled are relatively shallow.

Bench and Production drilling

Open pits and Underground mines (production), as well as Quarries are associated with bench and production drilling applications, the diameter of the drill bits used is typically 64-152 mm.
