摘要： A coal plow that can be moved lengthwise in opposite directions along a coal face has an axle projecting horizontally from its mining side. A tool supporting member is mounted on the axle for rocking parallel to the guide beam of the plow. At each end of the supporting member there is a plurality of independent blade holders disposed in a row extending upwardly beside the beam. The lowest blade holder in each row supports a bottom plow blade for engagement with the foot wall of the mine. Cutter blades have inner ends secured to the rest of the holders and have outer ends projecting toward the adjacent ends of the guide beam. Each of these holders is hinged to the supporting member on a substantially vertical axis so that the outer ends of the blades can swing laterally away from the guide beam.

摘要： Connected to a side of a longwall conveyor in a coal mine is one side of an I-beam type guide bar that extends lengthwise of the conveyor and is provided with upper and lower longitudinal guide channels containing the upper and lower lengths of an endless drag chain. Retaining plate means connected to the opposite side of the bar extend above and below it and also at least part way across the top of the bar but only part way across its bottom, whereby to leave space for passage of an arm connecting a guide block attached to the chain in the lower guide channel to mining equipment between the conveyor and a coal mine longwall.
摘要翻译：连接在煤矿中的长壁输送机的一侧，是沿着输送机纵向延伸的I型梁式导杆的一侧，并设有上下纵向导流通道，上部和下部纵向引导通道包含无限拖链的上下长度。连接到杆的相对侧的保持板装置在其上方和下方延伸，并且还至少部分地跨过杆的顶部，但是仅部分地穿过其底部，由此留下连接连接导向块的臂的空间到下游引导通道的链条到输送机和煤矿长壁之间的采矿设备。
