摘要： The invention relates to a mine roof support assembly for use in winning mineral material from a mineral mining working having a mineral face. The assembly comprises three roof support units positioned side-by-side along the face, and a goaf shield common to the three units. Each of the roof support units has a roof shield supported on a floor sill. The goaf shield is adjustable in height so as to extend from the floor to the roof of the working. Advance means are provided for advancing the roof support units towards the face, and further advance means are provided for advancing the goaf shield to follow up the advance of the roof support units. The further advance means acts between the goaf shield and the roof support units, and is such as to advance the goaf shield by a distance greater than the distance through which the advance means advances the roof support units.

摘要： Apparatus for controlling the position of a mineral winning machine, such as a plough, movable along a guide at one side of a scraper-chain conveyor employs cantilevered beams extending between the conveyor and roof supports as known per se. Brackets are provided at the goaf side of the conveyor and these brackets are pivotably coupled to the cantilever arms by way of flat pan-like components. Upstanding piston and cylinder units are positioned close to the conveyor goaf side wall preferably within protective walls of the brackets. These units are pivotably connected at their upper ends to the brackets and to extensions of the pan-like components so that the beams are effectively pivotably coupled to the units at positions offset towards the conveyor relative to the pivot connections with the brackets. The space between the conveyor and the supports is relatively unrestricted. The units are extended or retracted to tilt the conveyor and the guide whereby to control the cutting position of the machine.

摘要： A mine roof support has a main roof bar which is pivotably connected to an auxiliary forwardly-extendible bar. At least one piston and cylinder unit serves to swing the auxiliary bar about the main bar to bring the auxiliary bar into a roof-contacting position aligned with the main bar or into a stowed position beneath the main bar or into some intermediate position. One or more pivotable guide levers connect the auxiliary bar to the piston and cylinder unit. A guide member is also connected to the unit and slidably locates in longitudinal guideways formed in ribs or the like at the underside of the main roof bar.

摘要： A mobile mine roof support assembly has three mine roof support units coupled together by a common transverse beam. Roller devices are mounted beneath the floor sills of the support units. The roller devices are spring biased away from their floor sills so that they can lift the floor sills away from the floor of a working when the assembly is to be moved. At least one roller device of each support unit is a steerable roller device so that the assembly can be steered round bends. Each steerable roller device is pivotally mounted on its floor sill about a vertical axis, and is provided with an associated steering device. The steerable roller devices are preferably coupled together by means of a common steering device.

摘要： A mine roof support has a goaf shield with a lemniscate guide system linking the shield to floor-engaging skids. A walking-mechanism is disposed in a channel between the floor skids. In order to prevent rubble or goaf material from penetrating into the channel the guides of the lemniscate system have connections which are spaced one above the other and to which one or several screen plates can be removably and replaceably attached with the aid of push-in locking-bars. The screen plates also advantageously serve to keep the floor skids apart by a minimum distance to prevent jamming of the walking mechanism.
