Definitions

  • the present invention relates to a mechanized device for the mining of ore in a cut. It is advantageously used for the mining of long pruned ore in a bedding layer.
  • the mining of long-cut ore is generally carried out either by a cutter or by a planer (see for example DE-C-1 175 629).
  • the shearers are made up of drums fitted with picks (see for example FR-A-2 303 155). These cutters generally carry out slaughtering over the entire height of the working face. This process is well suited as a layer of hard or semi-hard ore with good strength.
  • the planes are masses provided with knives which are moved back and forth controlled by guides parallel to the cutting face.
  • Such planers are for example described in the book Exploitation des Mines by Whatever Victor VIDAL, Tome 1 from page 283.
  • the planers are used to make a bleeding in the ore layer at the bottom. The bleeding obtained is sufficient to obtain a natural separation of the ore up to a well-determined level constituting the crown under which the caps of the walking support piles will bear. Planing is well suited for thin, heavily sloped layers and for not too hard ores.
  • the felling device used is associated with a series of walking support piles aligned in front of which, parallel to the cutting face, passes a conveyor which collects all the ore.
  • the mechanized device according to the present invention makes it possible to completely mechanize the felling and the retaining in size when the layer is deburring.
  • the subject of the present invention is a mechanized device for the mining of ore in a size, comprising at least one walking support stack, a serving conveyor, a first planer associated with this conveyor and a second planer, characterized in that it further comprises a set of elements forming a metal plate, located between the sole and the stack cap, at the front of said device, over the entire length of the waist, said second plane being disposed at the front of said plate, each of the elements forming the metal plate being connected to the sole which corresponds to it by means of at least one jack.
  • the cylinders are advantageously hydraulic.
  • the functions fulfilled by the device are: for the metal plate: block any landslides coming from the front of the extensions of the walking support caps,
  • Each plate is connected to the sole of the corresponding stack by at least one jack having a stroke preferably such that the metal plate can advance by the step of the walking support.
  • the device according to the invention is such that each plate is connected to the stack which corresponds to it, in addition to at least one jack, by a passive jack comprising, fixed to its outer casing, one end of a jack of rearing up the other end of which is fixed to said plate.
  • a passive jack comprising, fixed to its outer casing, one end of a jack of rearing up the other end of which is fixed to said plate.
  • the set of plates aligned parallel to the cutting face and forming the metal plate advantageously carries at the front a guide for the back-and-forth movement of the plane.
  • the planer used can be any planer of known type.
  • a turret planer is preferably used so that the ore can be cut down at the level of the caps.
  • each plate is rigid.
  • each plate is formed of 2 parts and articulated in the direction of the length so that the rear part can oscillate around a longitudinal axis.
  • the oscillation can for example be 20 up or down without changing the direction of the plane.
  • the rear part of each plate is preferably slightly bevelled so as to give a certain flexibility of articulation to the set of aligned plates forming the metal plate.
  • the second planer makes it possible to attack the front of the deposit whatever the hardness of the ore treated.
  • the metal plate retains the landslide which cannot reach the unstacking conveyor.
  • the rear part can be raised to retain the landslide by closing its outlet, or lower it to clear the ore outlet on the contrary without changing the inclination of the plane.
  • Figure 1 is a partially cutaway perspective view of an installation according to the present application.
  • Figure 2 is a vertical sectional view of an installation according to the present application.
  • FIG. 3 represents the particular embodiment in which the plate is articulated (FIG. 3a: top view; FIG. 3b and 3c: sections along AA 'and BB', respectively).
  • each stack consists of an arrow (2), a cap (3) having an extension (4), and two soles (5), (5').
  • the soles (5) and (5 ') are connected to the cap using jacks (6), (6'), (6 ") (6" ') supplied in a manner not shown by a hydraulic network.
  • the cap In the type of battery represented in FIG. 1, the cap consists of a rear shield provided with flaps (7) by which the charred coal can be collected, being the roof and the crown and which falls on the racking conveyor (8 ) ( Figure 2).
  • the coal coming from the working face is collected on a serving conveyor (9) placed in front of the supporting piles (1,1 ', 1 ", ...) parallel to the working face.
  • This conveyor (9) carries guides (10) for the first planer (11).
  • a plate (12) carrying at the front a guide (13) for the second planer (14), is connected by the cylinders (15), (16), (17), (18) with flanges (5) and (5 ').
  • the cylinders (16) and (17) are thrust cylinders.
  • the cylinder (15) is not not active, it is in fact a simple slide which, with the jack (18), is used to tilt the chainring.
  • the triangulation constituted by the jacks (15) and (18) is essential if one wishes to be able to pitch up the platform and stiffen the assembly.
  • the tray-second planer + jacks system only rests on the coal at the front of the tray and on the stack bridges (points marked A and B in Figure 2).
  • the plate is articulated and comprises a box (19) and a flat part (20) joined together so as to be able to pivot with the aid of a jack (21).
  • the device according to the present invention is implemented in the following way:
  • a bleeding is practiced using the second planer carried by the plate in front of the stack slightly below the level of the hat.
  • a second phase we extend the hat extensions above the board.
  • the base is tapped with the first planer and then the racking conveyor is advanced. The entire stack can then advance one step towards the face. If the pile caps do not have extensions, the second phase can be omitted, the front end of the pile cap then making its place in the charcoal felled at the time of the shifting of the pile.
