    • A downhole recirculator for injecting two-phase lixiviant from a tubing string into a leaching interval of an in situ mine field injection hole, and for circulating the injected lixiviant within the leaching interval. The recirculator includes a core device which is adapted to be readily inserted or removed from its operating position in a fixture defining the upper limit of the leaching interval. The core device includes an induction valve arrangement whereby a primary flow of two-phase lixiviant supplied from the minefield surface by way of the tubing string induces a secondary flow of lixiviant from regions of the injection hole near the top of the leaching interval. The primary flow two-phase lixiviant is combined with the secondary flow lixiviant and injected to a region near the bottom of the leaching interval to establish a circulatory motion of lixiviant within the leaching interval.
    • 一种井下再循环器,用于将两相浸出液从管柱注入到原位矿场注入孔的浸出间隔中,并在浸出间隔内循环注入的浸取物。 再循环器包括一个芯装置,该芯装置适于在定义浸出间隔的上限的夹具中容易地将其从其工作位置插入或移出。 核心装置包括一个进气阀装置,由此通过油管柱从雷区表面供给的两相浸出液的一次流引起从浸出间隔顶部附近的注入孔区域的二次流动。 将主流两相浸出液与二次流浸剂结合并注入到浸出间隔底部附近的区域,以在浸出间隔内建立浸取液的循环运动。

    • A dust control system for a mining machine, particularly for controlling respirable dust in coal mining operations, comprising a ductwork system having intakes adjacent the cutter head of the mining machine, a fan for drawing air through the ductwork system, a flooded bed scrubber in the ductwork system upstream from the fan for entraining dust, including respirable dust, in the air in droplets of water, air flowing through the scrubber carrying the dust-laden droplets of water downstream from the scrubber, a sump below the ductwork system between the flooded bed scrubber and the fan, a demister in the ductwork system above the sump for separating the dust-laden droplets of water and directing them into the sump, and a pump for pumping the dust-laden water from the sump to a point adjacent the cutting head. A method of controlling dust is also disclosed.
    • 一种用于采矿机的粉尘控制系统,特别是用于控制采煤作业中的可吸入粉尘,包括:具有与采矿机的切割头相邻的入口的管道系统;用于通过管道系统抽取空气的风扇; 风扇上游的管道系统,包括可吸入粉尘,水中空气中的空气,流过洗涤器的空气,其携带洗涤器下游的灰尘的水滴;在淹水床之间的管道系统下方的集油槽 洗涤器和风扇,位于贮槽上方的管道系统中的除雾器,用于分离灰尘的水滴并将其引导到贮槽中;以及泵,用于将堆积的积聚的水从贮槽泵送到与切割头相邻的点 。 还公开了一种控制粉尘的方法。

    • Apparatus for and method of controlling the mining by a mining machine of a seam of material (e.g., coal) overlying or underlying a stratum of undesired material (e.g., clay) to reduce the quantity of undesired material mined with the desired material, the machine comprising a cutter movable up and down and adapted to cut down into a seam of coal on being lowered. The control apparatus comprises a first electrical signal constituting a slow-down signal adapted to be automatically operated to signal when the cutter has cut down into a seam of desired material generally to a predetermined depth short of the interface between the seam and the underlying stratum for slowing down the cutting rate as the cutter approaches the interface, and a second electrical signal adapted to be automatically operated subsequent to the first signal for signalling when the cutter has cut down through the seam to the interface for stopping the cutting operation, thereby to avoid mining undesired material with the desired material. Similar signalling may be provided on an upward cut to avoid cutting into the overlying stratum.
    • 用于控制采矿机采矿覆盖在不需要的材料(例如粘土)层上或下方的材料(例如煤)接缝的装置和方法,以减少用期望的材料开采的不需要的材料的量,该机器 包括可上下移动的切割器,适于在下降时切割成煤层。 控制装置包括构成减速信号的第一电信号,其适于自动操作以在切割器已经切割成期望材料的接缝时通常达到与接缝和下层之间的界面短的预定深度的信号,以供 当切割器接近界面时,减慢切割速度;以及第二电信号,适于在切割器通过接缝切割到接口以停止切割操作之后,在第一信号之后自动操作以进行信令,由此避免 用所需材料挖掘不需要的材料。 可以向上切割提供类似的信号,以避免切入上层。
