美国通用电气公司新近设计了一种适用于长壁采煤机自动切割SIS—100型煤层分界面传感器。通过检测切割力的变化,使长壁采煤机自动化。当遇到煤——岩分界面时,指示灯亮并显示电信号,使司机避开能损坏采煤机截齿和设备的坚硬岩层。这种SIS—100型传感器是通用设计的,它能用于任何长壁采煤系统;既适用于从软到硬的各种煤层,也适用于坚硬砂岩到页岩的不同特性的顶底板。
US General Electric recently designed a suitable for long-wall shearer automatic cutting SIS-100 type coal seam interface sensor. By detecting changes in cutting force, longwall shearer automation. When confronted with a coal-rock interface, the light is on and an electrical signal is displayed, keeping the driver away from hard rock formations that can damage the shearer’s picks and equipment. The SIS-100 sensor is a versatile design that can be used with any long-wall coal mining system; it is suitable for all types of coal from soft to hard as well as roof to floor features of hard sand to shale.
