Definitions
- This invention relates to transport apparatus and more particularly, though not exclusively, to transport apparatus suitable for use in mines tunnels and other excavations. 5
- One particular application of the apparatus of the invention relates to its use in longwall mining systems.
- Longwall mining is a mining system whereby equipment and effort are concentrated into a relatively small area of the mine.
- a longwall mine face can vary in width from 50 to
- the longwall mining system comprises two basic forms, namely advancing face 15 system and retreating face system.
- An advancing face as the term implies, advances, together with its roadways deeper into the area of material such as for example coal being mined, each day moving further away from the entrance main roadway.
- a retreat face starts at the furthest point required in the area of material to be extracted and retreats towards the entrance, using previously prepared roadways. In both cases the distance travelled varies 20 according to the area of material to be extracted and the mining layout adopted.
- .Longwall panels can vary in block length from 300 to 6000m and can be used to extract seam sections from 0.75m to 5m in a single pass.
- the headings are driven to the boundary of an area to be worked and then are connected together across the block of material such as, for example, coal to form the longwall face.
- This drivage is normally referred to as the "set up entry” or “face line” .
- the mine face thus developed will be equipped with an armoured flexible conveyor (AFC), commonly called a face conveyor, a power loader (shearer) which usually runs on the AFC, and a set of powered roof supports called chock shields.
- AFC armoured flexible conveyor
- shearer power loader
- the coal is mined by the shearer moving to and fro along the face conveyor, taking slices of coal or webs 500mm to 1200mm thick.
- the mined material is loaded onto a belt conveyor which transfers the material to the mine entrance.
- a transport apparatus which can be in the form of a monorail to which a series of carriages are mounted.
- the carriages are arranged to support the service hoses and cables which deliver power to the mine face.
- a problem associated with longwall mining and in particular, to retreat face mining is the limited access available to and from the mine face. As retreat proceeds the cables and hoses are compressed into a reduced area so as to form loops and these loops further limit access to the mine face. Furthermore, during the mining operation it is often necessary to supply various equipment to and from the region of the mine face. This often necessitates the mining operation to be shut down and the belt conveyor is used to transfer the equipment to the mine face.
- transport apparatus suitable for use in mines, tunnels and the like, the apparatus including a primary transport device which includes a primary support rail having a remote section, a plurality of primary carriages which are movable along the support rail, a remote section, the apparatus further including a secondary transport device which includes a secondary support rail operatively connected to one or more carriages of the primary transport device, the secondary support rail being disposed in the region of the remote section of the primary support rail and including a plurality of secondary carriages which are movable along the secondary support rail, the secondary carriages being adapted to receive an object or equipment to transfer the object or equipment along the remote section of the primary support rail.
- the primary carriages in the region of the remote section of the primary support rail are operatively interconnected so as to form a substantially rigid series of carriages.
- the term rigid means that the primary carriages in region of the remote section move together along the rail in fixed position to one another.
- the primary carriages forming the services of carriages each include a main body and at least one wheeled bogie which is adapted to travel along the primary rail, a cable support member and connector members interconnecting adjacent main bodies.
- the secondary carriages each include a main body and at least one wheeled bogie which is adapted to travel along the secondary rail, and connector members interconnecting adjacent main bodies so as to form a rigid series of carriages.
- the term rigid as used here has the same meaning as described above.
- the transport apparatus further includes drive means movable along the secondary support rail and operatively connected to the secondary carriages to cause movement thereof; and a plurality of individual auxiliary carriages operatively connected to the drive means and being adapted for movement along the second rail towards or away from one another.
- the apparatus further includes hoist means on one or more of secondary carriages for raising and lowering the carrier.
- the apparatus is disposed within a mine heading having two gate roads and a plurality of access roads therebetween and including an innermost access road wherein the remote section extends towards the mine entrance beyond the innermost access road.
- the system is, however, designed to operate in single or multi-heading panels.
- Figure 1 is a schematic side elevation of part of a transport apparatus according to the present invention.
- Figure 2 is a similar view to Figure 1 with a modified form of carrier
- Figure 3 is a schematic side elevation of another part transport apparatus, the right side of the figure connecting with the left side of Figures 1 or 2;
- Figure 4 is a schematic partial plan view of a longwall mine layout incorporating transport apparatus according to the present invention.
- FIG. 4 illustrates in partial plan view a schematic illustration of part of longwall mine.
- the view shown is for a retreat face type system.
- the body of material to be mined is indicated by reference number 200.
- the mine face is indicated at 50 and mining takes place in the direction of arrow B towards the mine exit.
- a heading 52 which comprises two gate roads 55 and 56 with a series of pillars 57 therebetween the gate roads being interconnected by a series of access roads 54.
- the access road which is most remote from the mine entrance is indicated at 53.
- the parallel gate roads permit a ventilation cycle to be created with air being delivered down one gate road and returned to the mine entrance via the other gate road.
- Gate road 56 provides a roadway by which personnel can reach the mine face 50.
- the gate road 55 has a belt conveyor 58 therein along which the mined material is removed from the mine and a transport device in the form of a monorail 60 which transports the service lines to the mine face 50.
- the access roads 54 permit access to between the roads and are also used to position power sources for the various equipment within the mine.
- a temporary support roof 59 is disposed at the mine face.
- the transport apparatus 60 is shown in detail in Figures 1 to 3.
- the apparatus 60 is in the form of a monorail which comprises a primary support rail 62 which is secured to the roof of the gate road 55 by means of mounting brackets 64.
- the support rail 62 comprises a series of interconnectable rail sections 65.
- the apparatus further includes a plurality of primary carriages 70 which are suspended from rail 62 via wheeled bogies 72.
- the carriages 70 in the region of the mine face are coupled together through coupling members 76.
- This rigid section is indicated by dotted line 61 in Figure 4.
- the rigid section 61 extends past remote access road 53.
- Each carriage 70 includes a cable support member 78 for supporting the service cables thereon.
- a section of supporting cable is shown in phantom in Figure 2 and indicated by reference numeral 75.
- the carriages 70 are pushed along the rail 62 by means of a stage loader 210 (see Figure 4). Because of the rigid section of carriages the service cables 75 in this area to will not form loops in this region, the loops commencing to form in a region beyond the roadway 53.
- the monorail apparatus 60 further includes a secondary support rail 80 which is operatively suspended from the primary carriages 70 by means of hook chains 82.
- the secondary support rail 80 is formed from a series of interconnected rail section 83.
- the carriages 85 are interconnected by coupling section 87.
- the carriages are adapted to support an element such as tray 90 as shown in Figure 1, or carrier 91 as shown in Figure 2.
- Pneumatic, hydraulic, electric or manual hoists 94 are adapted to raise or lower the carrying element 90 or 91.
- the secondary rail 80 is arranged in the gate road in the region of the rigid end section 61 adjacent the mine face.
- the area adjacent the mined section can be kept clear providing ready access and not be blocked by service cables and the like.
- the secondary carriages 85 are driven by drive means in the form of a traction drive 96.
- the traction device 96 is operatively connected a series of trolleys 98 which support air hoses 99 or other apparatus.
- the traction drive may in some instances be replaced by a winch or the like.
