    • The present disclosure generally relates to a method for controlling a shearer (10) in an underground mine. The method comprises setting a first cutting profile (50) including a plurality of desired positions (D i ) to be approached by a first cutting drum (12) in a first travel direction (E), advancing the shearer (10) towards the longwall face (2), and generating a second cutting profile (51) including a plurality of desired positions (R i ) to be approached by at least one of the first cutting drum (12) and a second cutting drum (14) in a second travel direction (F) of the shearer (10) based on the set first cutting profile (50), a plurality of actual advancing vectors (v i ), and a plurality of shearer orientations (O i ).
    • 本公开一般涉及一种用于控制地下矿井中的采煤机(10)的方法。 该方法包括设置第一切割轮廓(50),该第一切割轮廓(50)包括在第一行进方向(E)上由第一切割滚筒(12)接近的多个期望位置(D i),使所述采煤机(10)朝向所述长壁 (2),并且产生第二切割轮廓(51),所述第二切割轮廓(51)包括将由第二切割滚筒(12)和第二切割滚筒(14)中的至少一个接近的多个期望位置(R i) 基于所设置的第一切割轮廓(50),多个实际前进矢量(vi)和多个剪切方向(O i),所述采煤机(10)的行进方向(F)。

    • The present disclosure relates to a clearing plow (8) for loosening material of a material cluster, which blocks travel of a material winning plow (100) in a longwall mining installation (2). The clearing plow (8) may comprise a first bottom guide member (32) including a first guiding element (40) for guiding the clearing plow (8) along a plow guide assembly (6) of the longwall mining installation (2). The clearing plow (8) may further comprise a main body (30) supported by the first bottom guide member (32), and providing a loosening tool mounting face (64) extending across the first guiding element (40) in a lateral direction of the main body (30). In clearing operation, the clearing plow (8) may be moved against the material cluster to loosen material.
    • 本公开涉及一种用于松开材料簇的材料的清除犁(8),其阻止在长壁采矿设备(2)中的材料获取犁(100)的行进。 清除犁(8)可以包括第一底部引导构件(32),第一底部引导构件(32)包括用于沿长壁采矿设备(2)的犁式引导组件(6)引导清除犁(8)的第一引导元件(40)。 清除犁(8)还可以包括由第一底部引导构件(32)支撑的主体(30),并且提供沿着横向方向延伸穿过第一引导元件(40)的松动工具安装面(64) 主体(30)。 在清理操作中,清除犁(8)可以移动到材料簇上以松开材料。
