摘要： A double ranging drum cutter for long wall type machines for coal extraction is disclosed, which comprises a drum cutter body, a television camera mounted on the drum cutter body for picking up an image of a coal layer cutting portion of a lower bedrock being cut by a cutter drum, a television camera mounted on the drum cutter body for picking up an image of a coal layer cutting portion of an upper bedrock being cut by a cutter drum, and a video image processing unit mounted on the drum cutter body and connected to the television cameras, whereby the boundary between a coal layer and bedrock can be readily judged to permit extraction of much coal without cutting much bedrock and also the ratio of the area of a bedrock to the area of a coal layer in a portion of the bedrock being cut can be readily detected.
摘要翻译：公开了一种用于提取长壁型机器的双重滚筒式切割机，其包括滚筒切割器主体，安装在滚筒切割器主体上的电视摄像机，用于拾取下基岩的煤层切割部分的图像，该图像由切割鼓，安装在滚筒主体上的电视摄像机，用于拾取由切割滚筒切割的上基岩的煤层切割部分的图像;以及视频图像处理单元，安装在滚筒主体上并连接到电视摄像机，由此可以容易地判断煤层和基岩之间的边界，以允许在不切割太多基岩的情况下提取大量煤，并且在基岩的一部分中基岩的面积与煤层的面积之比被切割可以容易地检测。
