Abstract
The invention is a steel frame apparatus installed in a safe manner to provide support for the construction of a concrete (Shotcrete) bulkhead. In underground mines, bulkheads / barricades are used to contain solid material, liquids or as ventilation stops. The bulkhead sites are in dangerous areas and the installation of the bulkheads must follow the Mining Act. The Timony DT1947 onsite assembled apparatus meets the Mining Act requirements and the engineering containment specifications for use as a bulkhead and not only a barricade. The main steel components are an anchored top support beams, a locked wall frame matrix and an adjustable turnbuckle brace.
Description
SPECIFICATION:
This invention relates to the custom construction of reinforced concrete bulkheads and barricades for use in underground mines as containment for solid material, liquids or use as ventilation airflow stops.
Construction of concrete (Shotcrete) barricades is a common practice in underground mines. The most common use for the Shotcrete barricade is in the containment of pastefill (or sandfill) used in the backfilling process of previously mined out areas. This is done in order to maintain ground stability to the surrounding mining areas. As the entrances to the open areas are uniquely different and dangerous, due to falling rocks, it is necessary to custom construct these barricades from a safe distance as dictated by the Mining Act. A number of barricade systems (i.e. inflatable balloon) have been tried and failed both from the safety aspect and the structural engineering aspect. None have met the Mining Act requirement to be deemed a Bulkhead. The Timony DT1947 meets both requirements.
In the Timony DT1947 custom bulkhead frame system, structural steel components and fabrication techniques are used to meet the engineering and mining construction requirements for structural integrity. Also the Timony DT1947 meets the Mining Act requirement for safety working from the brow opening by the unique remote installation method and the final in place locking arrangements to hold the barricade wall frame matrix in an upright position ready for the application of remotely applied sprayed concrete.

This is done in order to maintain ground stability to the surrounding mining areas.

A number of barricade systems (i.e. inflatable balloon) have been tried and failed both from the safety aspect and the structural engineering aspect.

In the Timony DT1947 custom bulkhead frame system, structural steel components and fabrication techniques are used to meet the engineering and mining construction requirements for structural integrity. Also the Timony DT1947 meets the Mining Act requirement for safety working from the brow opening by the unique remote installation method and the final in place locking arrangements to hold the bulkhead wall frame matrix in an upright position ready for the application of remotely applied sprayed concrete.
When a mine has a requirement to construct a backfill bulkhead the mine engineering department needs to provide specific measurements for the size of the opening and the safe installation distance measurement, in order to manufacture the Timony DT1947 rigid steel bulkhead assembly. The measurements determine if 1, 2, 3 or more top beams (fig.4) will be required and the size of the wall frame (fig.10) matrix to be manufactured.
The Timony DT1947 rigid steel bulkhead assembly consists of field assembled bolt on the structurally engineered components which are delivered in a compact package suitable for the mine's conveying system to the underground installation location.
All the components (fig. 4 to fig. 17) that have been matched marked, are assembled inside the safety zone on the floor of the drift/tunnel ready for remote lifting into the final bulkhead wall position.
The Line up plate (fig.l) which includes the hinge bracket (fig.3), is installed by Dywidag resin anchor bolts (fig. 2) at the exact location on the drift/tunnel's roof/ceiling which has been determined by the Mine's Surveying measurements. The line up plate/hinge bracket assembly has been custom manufactured to provide a base for as many top beams (fig.4) that is required for that bulkhead location. The lineup plate is critical to this invention. Once the Line up plate has been installed, the floor assembled components of the Timony DT1947 can be raised into position for fastening with the 1" bolts by a mechanized rubber tired bucket loader or other mechanized lifting equipment that maybe available such as a pitman crane truck or "zoom-boom"
forklift. Once all top beams have been secured, the lifting equipment continues to raise the complete assembly (fig.7 to fig.17) until the wall matrix swings into the final position and locks (fig.5) automatically. The wall matrix assembly has been designed from the Surveyor's measurements with 12" of clearance all around so that it can swing freely into the lock position.
With the wall now locked in place the Bracing assembly (fig.7 and fig.8) can be connected by 1" bolt fasteners to the Top beam brace bracket (fig.6). The bracing assembly is adjusted and tensioned in place by the unique Turnbuckle Tensioners (fig.7).
A final check of the Wall matrix is made and any adjustments are made prior to application of the remotely applied fast setting spray-on concrete (Shotcrete) by the mine personnel.
What has been achieved with this invention has to provide mines with an engineered bulkhead wall system that can be installed in a remote and safe manner that can meet the Mining Act and the Mines own strict safety codes.
