Herrenknecht. Pioneering Underground Technologies 2 General idea of vertical shaft sinking machine General Focus: Safe and fast shaft installation in difficult ground conditions below ground water table. Main Features: Permanent holding of shaft-lining and controlled sinking

Underground works require some access for stopes, extraction of mineral resources, transport of ore and waste materials, water/power supply, ventilation of main and temporary accesses, drainage, transport of personnel and equipment. Typical underground mining access is shown in Fig. 3.

The right equipment is essential in designing and installing innovative hoisting, elevator and vertical conveyance systems. Our capabilities include service, slope (incline), emergency escape and production hoists — everything it takes to transport …

Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects, differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the ...

Shaft construction. A shaft is defined as a vertical or inclined permanent opening that gives access and services various levels of a mine. Shafts are designed according to their required purpose and depending on the demands set out. Types. Shafts can be either vertical or inclined.

Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.

bored tunnel. The main collider ring will be connected to the surface by clusters of vertical shafts which provide access for personnel, utilities, ventilation and equipment including the 17m long magnet cryostats. These shafts are located on the Service Areas at intervals of ap-proximately 4.4km around the ring.

Transferring the alignment underground For long tunnel excavation is carried inward from both parties. But vertical shafts are also sunk up to the required depth along the alignment of the tunnel at intermediate locations along the routes. The vertical alignment can be done by Plumb bob; Optical collimator; Laser

Vertical Shaft Sinking Machines (VSM) in operation For quick and reliable construction of vertical shafts, Herrenknecht developed its VSM (Vertical Shaft Sinking Machine) technology, today an established product on the market. This unique mechanized shaft sinking equipment shows its strengths particularly below groundwater.

Using the full-bottom method, Herrenknecht's SBM sinks shafts up to 12 meters in diameter and 2,000 meters deep. To develop deep deposits safely, economically, and above all quickly, Herrenknecht engineers worked with mining company Rio Tinto to develop the Shaft Boring Machine (SBM). The highly mechanized machine has been designed for full ...

Many mines have vertical shafts for transporting miners and equipment to the work areas and slopes with conveyor belts for bringing the coal out of the mine. Surveys must be made to keep the slopes in alignment, both horizontal and …

Many underground mines use an inclined shaft fo r the transport of pe rsons, materials and equipment to and from the underground. Figure 3 shows an inclined drift at Ikeshima Colliery. Figure 3: Inclined shaft at Ikeshima Colliery The inclined shafts are often used also for belt conveyor transport, and therefore are

Levels are established at 200-foot vertical intervals, and level development comprises the cutting of shaft stations and skip pockets, crosscuts to the vein with extensions to provide room for tail track, pump, and motor-charging stations near the shaft and drifts on the vein. Drifts are 13 by 13 feet in cross section and are timbered with ...

Figure 1: Example layout of an underground mine An inclined shaft is excavated for transporta tion of personnel and supplies in addition to a vertical shaft for hoisting mined ore and a ventilation shaft for enhancing circulation of fresh air with the aid of a fan. Alternatively, an inclined shaft can be used for main ore

increases greatly the service life of the bunton of the shaft equipment [17]. Fig. 4 New bunton construction of mine-equipment shafts. III. CONCLUSION The construction of a bunton of stiff shaft equipment of vertical shafts was developed, with the upper flange of H-beam, protected by strictly fixed metal bracket.

Underground mining surveys require specific techniques due to geometric constraints such as vertical shafts and narrow passages. There has been a growing demand for automated underground surveying solutions to measure and record the progress of underground mining works, monitor cavity deformations, and assess the stability of …

Miners can access slope mines by moving down an incline rather than a vertical shaft. In shaft mining, a shaft is dug straight down into the Earth to access buried deposits. People get in and out of the mine through lifts in the shaft, and additional shafts may be dug to create emergency exits and deal with ventilation needs.

In an underground transport system, for instance, the tunnels are driven to connect inclined or vertical shafts (points of surface entry to the transport system) whose relative locations are established by surface surveys. Thus the underground control networks must be connected and orientated into the same coordinate system as the surface networks.

The shaft will be serviced by a 65 t payload cage and counterweight by means of a Koepe winder, which will allow Mining to lower its continuous mining equipment into the underground workings.
