昆阳磷矿是山坡露天矿,分两个采场同时作业,工作线较长,东西长达两公里,南北有半公里以上。采场内,各种机械设备较多,若有事需联系或设备发生故障要及时处理,专靠生产调度人员来回奔跑,往往需3～4个小时,影响生产。1966年矿山刚投产时,在主要设备上安设电话,建立了有线电话通讯系统。但因电铲、穿孔机、推土机移动频繁,显然此系统难以适应。自1974年后,改用无线电通讯机来代替。最初用硅两瓦军用电台,效果不够理想;其后又用JMD-1型单工报话机,效果尚好。直到1982年采用了JDD—8A型双工无线电话机,形成了本矿露天采场无线电通讯网路,并还可与有线电话系统汇接通话,大大改善了生产指挥系统的通讯工作。
Kunyang phosphate rock is a open pit mine, divided into two stope at the same time homework, work line longer, things up to two kilometers long, more than half a kilometer from north to south. Stope, a variety of mechanical equipment more, if something needs to be contacted or equipment failure to be handled in time, rely on the production scheduling staff to run back and forth, often take 3 to 4 hours, affecting production. When the mines were put into operation in 1966, they set up telephone lines on major equipment and established a telephone and telephone communication system. However, due to shovels, piercing machines, bulldozers moving frequently, it is clear that this system is difficult to adapt. Since 1974, the use of radios instead. The first two-watt military military use of silicon, the effect is not satisfactory; then use JMD-1 type simplex telephone, the effect is good. Until 1982, the JDD-8A duplex radiotelephone was used, forming the mine’s open-pit radio communication network and also connecting with the wired telephone system to greatly improve the communication of the production command system.
