A mineral mining installation (1) incorporates a conveyor (2) composed of pans (4). A drive assembly (16) is attached to the drive head (10) and is arranged to drive the conveying flight of the conveyor. A guide track (30) is provided on the goaf side of the conveyor pans (4) extending the length of the face and up to the connection between the drive assembly (16) and the drive head (10). A machine (40) has shoes (48) which slide on the track (30) and rollers bearing on a further track on the face side of the conveyor, the machine underframe (44) thus straddling the conveyor (2). <IMAGE>
Description
SPECIFICATION
Improvements in or relating to mineral mining
installations
This invention concerns improvements in or relating
to mineral mining installations.
In particular, this invention has reference to such
installations for use at the face in a coal mine, an
installation including an armoured flexible conveyor
arranged adjacent to the coal face for guiding a
mineral mining machine movable reciprocally there
along. The conveyor extends the whole length of the
face terminating at each end in a roadway, the
discharge end of the conveyor being associated with
a stage loader which conveys the won mineral onto
a belt conveyor for transport away from the face
workings. One of the problems attendant upon
installations of this kind is that during operation
when the machine is mounted on the conveyor, the
drive head of the conveyor forms an obstacle to the
path of movement of the machine which, as a result,
cannot fully progress up to the end of the conveyor.
It is, however, advantageous and desirable that the
machine should be able to cut mineral beyond the
end of the conveyor and up to the boundary of the
roadway in order to facilitate stable hole and rip
elimination. Hitherto, one method of achieving this
has involved the provision of specially designed
machine bodies which can slide relative to their
supporting underframes which in turn bear directly
on the conveyor. In addition or alternatively ramps
have been provided in the vicinity of the drive head
for elevating the machine to enable it to cut at the
required height to eliminate ripping operations. As
will be understood these methods can require
complicated and expensive structures.
An object of the invention, therefore, is to provide
a mineral mining installation with improved means
for allowing the mining machine to travel further
towards the end of the conveyor without the sliding
or ramping referred to above.
Accordingly the invention provides a mineral
mining installation including an armoured flexible
conveyor comprising a plurality of line pans and a
drive head, a drive assembly being connected to the
drive head, a guide track located on the goaf side of
the conveyor pans and extending substantially the
whole length of the conveyor, a mineral mining
machine including a body supported by an under
frame, the underframe being provided at least on the
goaf side with shoes which are adapted to bear on
the guide track.
The guide track preferably extends between the
drive assembly and the line pans in the vicinity of the
drive head to allow the mining machine to move, in
use, as far as possible towards the end of the
conveyor up to the connection between the drive
assembly and the drive head, the track in this region remaining at the same general level as for the rest of
its length along the face.
The guide track may conveniently be disposed on
the goaf side of the conveyor pans at approximately
the same level as the top flanges of those pans. In an
alternative mode, the guide track may be at an elevated level relative to the top flanges of the conveyor pans but offset therefrom to be on the goaf side thereof.
The mining machine may advantageously have a further support shoe arrangement on the face side of the conveyor, the arrangement including a roller bearing on a further track formed by plates attached to the conveyor pans, this track extending substantially the same distance as the guide track.
It is envisaged that the present invention will have particular, but not exclusive, application where the means of machine traction is chainless and accordingly the relative locations of the guide tracks to the conveyor pans will depend upon the type of haulage to be adopted.
By way of example only, one embodiment of mineral mining installation according to the invention is described below with reference to the accompanying drawings in which:
Figure 1 is a side view;
Figure 2 is a plan view of Figure 1 with parts removed for clarity: and
Figure 3 is a cross-sectional view.
Referring to the drawings, a mineral mining installation is shown at 1 and includes an armoured flexible conveyor 2 comprising a plurality of pans 4 each having top flanges 6, 8 at the face and goaf sides thereof respectively. The conveyor 2 has a drive head 10 beneath which is positioned a stage loader conveyor 12 attached to the conveyor 2 as at 14. A drive assembly 16 for the conveyor 2 includes a motor 18, a fluid coupling 20 and a gearbox 22, the axis of the motor and coupling lying parallel with the longitudinal axis of the conveyor.
A guide track 30 is disposed on the goaf side of the conveyor pans 4 at a level as shown in Figures 1,2 and 3 just above the level of the top flange 8.
A mining machine 40 of the single ended ranging drum shearer type has a body 42 supported by an underframe 44 which bridges the conveyor 2 and has goaf side support legs 46 carrying shoes 48 which bear and slide on the guide track 30. On the face side of the machine, the underframe 44 has further support legs 49 which have rollers 52 which bear on a further track 54 consisting of plates 56 attached to the pans 4.
The machine 40 of Figures 1, 2,3 is shown as having a chainless haulage traction system 60 which includes a self-contained drive 62 on the machine body 42 including a drive member engaging a static and rigid rack 64 disposed adjacent the guide track 30.
In use, the machine 40 traverses the conveyor 2 reciprocally therealong, the cutter drum 70 extracting mineral from a face (not shown) along which the installation 1 is arranged, won mineral being conveyed by conveyor 2 towards the drive head 10 when the mineral is discharged onto the stage loader 12. Because of the provision of the guide track 30, the machine 40 is able to move right up to the drive head 10 and thus the cutting element can reach across the full width of the roadway (not shown) in which the stage loader 12 is located. Since the guide track 30 in the region of the drive head 10 is at the same level as its remainder along the rest of the face, the machine 40 does not have to climb any ramp.
Additionally, it can be seen that no special slide arrangements are necessary to allow the machine body to move further into the face end than the underframe will allow.
The straddling feature of the invention whereby the machine underframe completely bridges the conveyor and is supported by shoes travelling on tracks outside the lateral limits of the conveyor coupled with the extension of the goaf side guide track between the drive assembly and the conveyor provide a fresh departure in mining techniques and further add to the scope for stable hole and rip elemination.
