Rock reinforcement and ground control are key issues in underground excavation.
One scope of research, which is in particular of interest for underground tunnelling,
are self drilling anchor products. In the past decades, substantial
technical advances in the development and design of these systems have been
accomplished. On the basis of some practical examples, this manuscript illustrates
the development and successful application of self drilling anchor system.

The main features of all self-drilling anchors and rock bolts are the application of a
single-use drill bit in combination with the anchor rod being used as a drill steel. Thus,
the anchor or rock bolt is connected to the hydraulic rock drill by an adapter device
and installed in the way a conventional borehole is drilled. In modern underground
mining and tunnelling, the following types of self-drilling anchors and rock bolts are in
development or already available:
− Self-drilling hollow bar bolts
− Self-drilling resin grouted bolts
− Self-drilling friction bolts
− Self-drilling mechanical anchors

Metis has significant experience and know-how in the supply of self drilling anchor, components, finished goods, specially designed/engineered equipment, and services from China. The company caters to medium to large scale clients who are doing projects.

The self-drilling bolt is a hollow rod with coarse thread which is a design similar to the drill rod. The bar, being hollow inside, allows passage of water / flushing air during drilling; as well as, injecting grout or resin. This bar carries at its end a bit or cutting tool with several holes sweeping, which is lost in the perforation process.

The bar to the being threaded along its length allows the coupling successive bars using connectors or couplets.

The self—piercing bolt consists of a hollow rod with thick thread whose design is similar to that of a drilling rod. The rod, which is hollow, allows water/purge air to circulate during drilling; it also allows cement grout or resin injections. This rod has a bit or cutting tool with various mapping drills, which is lost in the drilling process.

The rod, which is twined across its length, allows rods to be successively coupled through the use of connectors or couplets.

The design of the self-drilling bolt considered a cold rolling to form a standard thread profile (R25, R32, R38 and R51 and T76). As accessory, a plate and nut are used.

In mining, tunneling and specializing civil engineering are used as reinforcement bolts.

A self-drilling bolt is comprised of:

• A hexagonal nut.
• A support plate.
• Extension couplings, consisting of several sections of bolt.
• Hollow bar.
• Sacrificial rod.

Applications and uses

They are typically employed in extremely poor rock and soil susceptible to collapse as an alternative casing drilling.

Among the applications include: micropiles, soil nailing, slope stabilization, consolidation, marchiavanti, etc.

Advantages

• High quality for a limited life.
• Major length of anchoring installed.

Metis offers the tightest tolerances in the industry. We are able to do so through stringent control of our process parameters and because of
proprietary processes that we have developed. With over 4 years of experience in operating rock bolt, we have a complete understanding of the
primary parameters that are responsible for variations in product quality and we are able to control these parameters very carefully.
Similarly, we have developed special surface treatment and cold sizing processes that allow us to ensure extremely good dimensional control
as well as surface cleanliness. In case of rock bolts, tighter tolerances translate directly into cost savings.
Metis rock bolt systems effectively improve the stability of underground rock masses. The increased load bearing capacity of the rock
conditions enables an early construction start, thus providing both technical and economic advantages.Thanks to our systems’ flexible
application options, our customers can choose next to mechanical and chemical anchors and bolts from a variety of anchoring systems, which
are all customtailored to satisfy individual project requirements.

Rock Bolts are an essential part of concrete construction. These are bolts, placed in the concrete with the threaded side up. They allow you
to secure wall forms or other portions of the construction onto the concrete foundation slab. It’s important when placing rock bolts to
place them carefully and accurately, since moving them later will be extremely difficult and will hold up your construction project
significantly.
Equipped with anchor head,stop-grouting plug and couples,rock bolt can provide strong bonding stress between rock bolt and boreholes to
install rock bolt in the center of borehole,so that the bolt will be able to acquire average procetion thickness and the durability of rod
body can be extensively improved.
Metis’s rock bolt can completely solve the problems of conventional anvhoring system.
Metis – We aim to better our position as the leading rock bolt supplier and warehouse distributor of anchor bolt in the world,by providing
our customers with value for money,quality products and timeous service.
Metis developed its rock bolt system technology and manufacturing capabilities in response to problems associated with construction.And Metis
committed to become the first-class self drilling rock bolt manufacturer.
