    • A method of controlling a shearer is disclosed. The shearer may be configured to travel along a longwall face to extract material with a first cutting drum and a second cutting drum. The method may include setting a first cutting profile including a plurality of desired positions (Di) to be approached by the first cutting drum in a first travel direction (E). Further, the method may include determining a plurality of actual advancing vectors (vi) indicating a change of a position of the shearer resulting from advancing the shearer towards the longwall face. The method may also include determining a plurality of shearer orientations (Oi) along the longwall face. In addition, the method may include generating a second cutting profile to be approached by at least one of the first cutting drum and the second cutting drum in a second travel direction (F) of the shearer.
    • 公开了一种控制采煤机的方法。 采煤机可以被构造成沿着长壁面行进以用第一切割滚筒和第二切割滚筒提取材料。 该方法可以包括设置包括第一切割滚筒在第一行进方向(E)处接近的多个期望位置(Di)的第一切割轮廓。 此外,该方法可以包括确定多个实际前进向量(vi),其指示由于将采煤机推向长壁面而导致的采煤机位置的变化。 该方法还可以包括沿长壁面确定多个剪切方向(Oi)。 此外,该方法可以包括产生第二切割轮廓,该第二切割轮廓将在第二切割滚筒和第二切割滚筒中的至少一个沿着第二行进方向(F)接近。

    • A method for controlling a longwall mining operation, including a face conveyor, at least one extraction machine, and a hydraulic shield support, in underground coal mining. Using inclination sensors disposed on at least three of the four main components of each shield support frame, such as floor skid, gob shield, support connection rods, and gob-side region of the top canopy, the inclination of the shield components relative to horizontal is ascertained in the direction of step. In a computer, the ascertained inclination data is compared with base data stored in the computer that defines the geometrical orientation of the components and their movement during stepping. From the comparison, a respective height of the shield support frame, at the forward end of the top canopy, is calculated as a measure for the face opening.
    • 一种在地下采煤中控制长壁采矿作业的方法,包括面部输送机,至少一台提取机和液压盾构支架。 使用设置在每个屏蔽支撑框架的四个主要部件中的至少三个的倾斜传感器,例如地板滑板,料滴屏蔽,支撑连接杆和顶部顶盖的料滴侧区域,屏蔽部件相对于水平面的倾斜度 在步骤的方向确定。 在计算机中,将确定的倾斜度数据与存储在计算机中的基本数据进行比较,该数据定义了组件的几何取向及其在步进过程中的运动。 根据比较,计算顶盖顶端处的屏蔽支撑框架的相应高度作为面部开口的度量。
