Wood Vs. Steel Support Beams - B

Durability

Steel support is very durable and is more likely to survive natural disasters like hurricanes, earthquakes, and fire. Steel also does not rot, mold, or dry out. It is not subject to infestation and will not shrink or warp in different weather conditions. Steel supports, walls, and frames stay straight and flat through construction and during its lifetime better than wood.

Construction

Steel beam support can be pre-engineered or prefabricated, meaning the construction is done beforehand. This can save time and money and is generally an easier way to construct a building. This is done by constructing certain parts, bodies, or pieces in a factory before they are shipped to a construction site.

Environment

Both steel roof support and wood have claims to being green, or environmentally-friendly. Wood grows naturally so the energy needed to process it is little. Iron on the other hand must be dug from the ground and then processed in large factories. This can create large amounts of greenhouse gases and pollution. However, while wood is a renewable resource, it is dependent on the time it takes to grow a tree and whether or not enough trees are growing. Steel is not a renewable resource, but it easier to recycle than wood. In fact, a great deal of steel in the United States is recycled.

Wood Vs. Steel Support Beams - A

Wood has traditionally been the building material for most support beams in home construction. However, with steel proving itself as an excellent building material in large buildings, it is slowly replacing wood construction in conventional homes as well. This is due to many factors, from price and availability, strength and durability, and the elimination of misconceptions. Although wood remains important in home construction, steel support provides many advantages. Steel buildings can even be pre-engineered to speed construction and efficiency.

Price
Fortunately, wood and lumber is a renewable resource. Unfortunately, the rate of its needs versus how fast it is replanted is much higher. This means lumber prices can fluctuate. Steel mining support , on the other hand, is readily available in large quantities. It is also recyclable. Steel prices, although historically higher than wood, is now on par with wood. The pricing of steel is usually consistent.

Strength
Steel support beams have very high load strength and can handle stress much better than wood. Aside from being one of the strongest building materials available for home construction, it is a manufactured metal, meaning its strength isn’t dependant on things like knots, twists, or defects that may be found in wood.

Underground Mine Roof Support & Mine Roof Bolting

Mining and Ground Support

Satrise® friction rock stabilizers are used for underground or surface support in many applications:

Underground Mine Support & Mine Roof Bolting

Every kind of underground mine uses Satrise® friction rock bolts for mining and ground support. Miners use them for mine roof bolting and mine roof support as well as to pin mesh, hang conveyors, hold pipes, and cables, secure rails in place, and for other needs.

Ground Support for Tunnels and Other Excavations

Satrise® stabilizers have solved many problems for contractors in construction and in maintaining railway and road tunnels, hydropower tunnels, powerhouse and storage caverns, shafts, water and sewage tunnels, and others.

Ground Support for Surface Jobs Satrises are being used more often for above ground applications or anywhere reliable ground stabilization is needed. Open-pit mine and quarry operators use them to stabilize high walls for the most effective ground and mining support. Open-pit miners find that using Satrise® stabilizers with mesh can permit a steeper mining angle, reducing overburden removal.

Contractors find Satrise® friction rock stabilizers ideal for attaching screen to control spalling cuts. Construction contractors use them with mesh to tie back the ground and contain rock falls on steep highway cuts, as well as in building excavations.

DESIGN AND SUPPORT OF TUNNELS

When a tunnel is excavated in all but the most competent of ground conditions it is an inevitable consequence that some form of mining support will be required if the tunnel is to retain adequate stability and/or maintain sufficient dimensions to facilitate its use in the intended manner.

The form and function of the support will vary according to a wide range of factors apart from just geotechnical considerations and it would seem that for every different tunnel there is a different lining solution 

Tunnel linings: main types. Tunnel linings are grouped into three main forms some or all of which may be used in the construction of a tunnel:
1. Temporary mining ground support
2. Primary lining
3. Secondary lining 

Temporary mining ground support. In rock tunnels where the ground has insufficient stand-up time to allow the construction of the primary lining some distance behind the face, then some form of temporary ground support applied at the- tunnel face is required eg rock bolts, shotcrete and steel sets tunnel support. 

Such support is not required in soft ground in conjunction with a shield driven tunnel as temporary ground support is provided by the body of the shield itself.

Primary lining. A primary lining is the main structural component of the tunnel support system which is required to sustain the loads and deformations that the ground may induce during the tunnel's intended working life. A further function performed by the primary lining is the control of water egress (exit) and ingress (entrance). 

Secondary lining. Various tunnels require smooth bore profiles for their intended use, eg sewer and water tunnels or aesthetic finishes for public usage, eg highway and pedestrian tunnels. Erosion and corrosion protection for the primary lining and further waterproofing may also be required, all of which are provided by secondary linings.

The terms temporary, primary and secondary linings are not always defined on a consistent basis in various texts 

Common Support Types used in Mining Engineering Tunnels

From the earliest days of mining until the middle of the 20th Century timber was the standard supporting medium due to its abundant availability and attractive strength and load-deformation characteristics. Traditionally, timber has been employed extensively for support in coal mines even at shallow depths as roof support is required owing to the weakness of the rocks associated with the Coal Measures. in hard rock mines, however, this has not always been the case as the stronger rock types often provide safe, self-supporting tunnels particularly in shallow depth conditions.
The load-deformation characteristics of wood make it a suitable material for mine support purposes as even in the post-failure state it retains the ability to support a load even at high values of strain.
An early use of timber for support of mining tunnels was the herringbone system and appears to have led to development of the steel arch support. The use of timber required considerable craftsmanship and time and effort to perform the support operations. Large amounts of timber were required in broken ground conditions and even then such support tended to be less than satisfactory in view of the significant voids which were inevitably left. The use of the rolled steel joist significantly contributed to reducing the time and effort, in addition to skill, involved in erecting mine roadway supports. There was also a significant improvement in safety as a result of the adoption of steel mining supports as opposed to timber for use in mining tunnels and roadways. Undoubtedly, steel supports were better suited to the significant deformation characteristics of coal mining tunnels and roadways than was that of timber. The superior strength and durability properties of steel supports in addition to ease of construction were over-riding factors when compared to wood for support purposes.
Wood is rarely used as a main form of tunnel support in the majority of modern mines in developed countries. Standing steel sets and rockbolts are the most commonly applied forms of support in such mining excavations. Concrete and shotcrete supported tunnels have a relatively limited application but they tend to be used in special situations rather than as a general tunnel lining technique. There are some exceptions, however, and one example is that of deep level main tunnels used for developing mining districts in the Campine Coalfield, Belgium. These tunnels have been supported by concrete segmental types and given significant stability and durability advantages. This form of support has also found application in the coal mining industries of other countries where long life (>50 years) tunnels are required.

Mine and Tunnel Roof Support Systems

Sliding Arched Canopy

Satrise Industry has developed procedures and products for specialized mining support of caved areas and unsupported roof. The Sliding Arch Canopy System provides support and a safe work environment as you clean up roof falls or advance through broken strata. Once in place they can be cushioned using Satrise Geotek Bags filled with rock dust or other material. Contact Satrise to discuss your application.

Steel Arch Supports
Structural steel arch supports and circular ring sets are used for mining roof support or ground control where severe conditions are anticipated or to maintain critical areas of a mine or tunnel where roof bolting or cribbing is not sufficient or practical. Used in conjunction with Satrise Lagging systems, arches can solve difficult conditions on a long-term basis.

Steel arch supports range from almost rectangular shapes, to semi-circles, to Gothic shaped structures. Each has design advantages and disadvantages depending on the application.

Some of the standard configurations are shown to the figure, however the best approach is to determine your specific needs and layout a support around your specific criteria. We take into consideration your requirements as far as clearances, load capacity, handling, and other site specific issues and provide an arch to best fit your needs.
