在多水平(中段)开采的井下矿山中,为了保证矿井卷扬提升工作的安全进行,规定有各种联系信号。(1)罐笼运行区间信号;(2)工作制度信号(运送人员、设备、提矿和检修等);(3)卷扬机操作执行信号(上升、下降和停止操作)。前两种信号以醒目的灯光标志向卷扬机司机显示,而操作执行信号则是靠电铃响声的次数和长短加以区别。目前国内很多中小矿山采用下列操作执行信号制度:一声铃响:停止二声短铃:上升三声短铃:下降二声长铃:缓慢上升三声长铃:缓慢下降目前,电铃响声的次数和长短是总信号工用按钮开关或用能复位的手拉开关发出
In the multi-level (middle) underground mine exploitation, in order to ensure the safety of the hoisting and hoisting work of the mine, there are all kinds of contact signals. (1) Cage operation interval signal; (2) Working system signal (conveying personnel, equipment, mining and maintenance, etc.); (3) Winch operation execution signal (rising, falling and stopping operation). The first two signals are displayed to the winch driver with eye-catching light signs, while the operating signals are differentiated by the number and length of bells. At present, many small and medium-sized mines in our country use the following operations to implement the signal system: One ring: Stop two short rings: Three short rings up: Two second ring down Long bells: Slowly rise three Long bells: Slow down Currently, the number of bells and The total length of the signal is to use the button switch or hand reset switch can be issued
