摘要： The mobile stope support apparatus comprises a number of individual units (10) which are interconnected by hydraulic cylinders (12). Each of the units (10) has a series of upright, double-acting legs (20). The legs (20) have independent bases of rounded shape and they are pivoted to an overhead canopy (22) which can be raised and lowered by appropriate actuation of the legs. Each unit also has a fore-and-aft hydraulic cylinder (34) which is connected to a common rail (37), the cylinder (34) being pivotable, by the action of a cylinder (36) in an upright plane to raise and lower the rail. By appropriate sequential operation of the various cylinders, the units can be advanced in turn to advance the whole apparatus. In addition, by appropriate operation of the cylinder (36), the front legs (20) can be lifted off the footwall to facilitate movement of the unit over a rough or uneven footwall.

摘要： A bi-directional shearing machine mines a longwall face at the bottom of a thick mineral seam in a retreat operation under the protection of a row of adjacent powered roof supports each of which extends in a direction transverse to the solid face. Progressive advance of these roof supports allows the overlying mineral strata to cave. Each roof support is separated into articulated forward and aft units provided with separate sets of hydraulic props and having their solid canopies interfitted in end-to-end relation. The bases of the two units are interconnected with a push-pull hydraulic ram which enables relative longitudinal movement between the two units so that they may be advanced independently along a common axis toward the solid longwall face as the work progresses. During the advance of the forward units to provide face support, plowing and loading of caved mineral on the gob side may proceed without interruption. To accelerate caving, the aft units are independently advanced with an attached gob side chain conveyor and gob plow retracted beneath their canopies for protection. Starting from this retracted position, the gob conveyor and gob plow are allowed to load gradually out into the flushed coal.
摘要翻译：双向剪切机在一个相邻的动力屋顶支撑的保护下，在一个后退操作中，在一个厚厚的矿物接缝的底部开采一个长壁面，每个相邻的动力屋顶支撑沿垂直于实心面的方向延伸。这些屋顶支撑的进步使得上层的矿物层可以洞穴。每个屋顶支撑分离成铰接的前后单元，其具有单独的液压道具套件，并且具有以端对端关系相互配合的固体檐篷。两个单元的基座与推拉液压柱塞相互连接，其能够在两个单元之间进行相对的纵向运动，使得当工作进行时，它们可以沿公共轴线独立地朝向实心长壁面前进。在前进单位提前提供面部支撑的情况下，可以在不间断的情况下进行在料滴侧犁耕和装载塌陷矿物。为了加速塌陷，尾部单元独立地前进，附着的料滴侧链式输送机和在它们的檐篷下方的料滴犁保护。从该缩回位置开始，允许料滴输送机和料滴犁逐渐加载到冲洗的煤中。

摘要： A mine roof support assembly comprises three basically similar mine roof support units positioned in a side-by-side relationship along a beam. The central unit is fastened to the beam for movement therewith, and the two outer units are flexibly connected to the beam by respective guide rod assemblies. Each of the outer units is provided with an alignment device, such as a short working stroke hydraulic ram, which acts on the beam in the direction of the longitudinal axis of the beam.

摘要： A roof support for use in mines is moved by its own drive mechanism while under permanent load. The support comprises two side-by-side lower carriages with articulated tracks, cross members joining those carriages and an arm articulated to the cross members so as to swing up and down under the action of a jack connected between the arm and the cross members. At least one upper carriage having an articulated track is carried on the upper end of the arm, and is pushed against the roof of a mine gallery by the jack.

摘要： A longwall mining system includes at least one face end roof support having a longitudinal length, and at least one near end roof support adjacent the face end roof support. The near end roof support has a longitudinal length substantially shorter than the face end roof support longitudinal length. There is also at least one face roof support adjacent the near end roof support, and the face roof support has a longitudinal length substantially shorter than the near end roof support longitudinal length. There is also a forward conveyor extending forward to and attached to the face end roof support, the at least one near end roof support, and the at least one face roof support, and a rearward conveyor extending rearward of and attached to the face end roof support, the at least one near end roof support, and the at least one face roof support. This creates an effective cave line at an angle to the coal face, that helps reduce the goaf pressure on the face end, thereby increasing the stability of the main gate roof support.

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： A walking mine roof support wherein one or more roof engaging caps are pivotable on the upper end of at least one extendable pit prop which is mounted on the floor engaging base. Balancing rams connect the rear ends of the caps with the base or such rams carry bars which are movable against the roof behind the caps. The props and the rams are operated by a hydraulic control system in response to signals from pressure gauges mounted on the front and rear ends of the caps. Such signals indicate changes in pressure which the mine roof exerts against the respective ends of the caps.

摘要： Coal in the roof of a seam being mined by the long wall method is recovered by supporting an elongated area of the seam roof using a plurality of cradle supports, the front cradles being moved forward stepwise parallel to the long wall to form a passage with cantilevered roof supporting arms of the rear cradles. When the rear cradle at one end of the passage is moved forward into engagement with the front cradles, the coal in the roof is left unsupported, is collapsed, and is removed via a conveyor and a loader in the passage.
