摘　　要：专用线电机车通信已在美国煤矿试验成功，较好地解决了电机车载波通信距离和噪声干扰问题；在国内也进行了理论研究和短距离实验。为使这种简单易行的通信方式引入我国煤矿，我们研制了实验用通信机，在三个煤矿井下运输大巷进行了实地测试，测试结果为我国煤矿井下建立和完善专用线通信系统提供了有实用价值的参考数据。The trolley communication through a dedicated-wire has been successfully used incoal nunes of the USA. It resolves the problems related to the communication distance and thenoise interference presented in the trolley communication. The theoretical research and testsfor short distance communication have also been carried out in China. In order to utilize thesimple and feasible communication technology in domestic coal mines, we have developed communication devices and made tests in tunnels of three coal mines. Results of these tests give thevaluable reference data to establishment and improvement of the underground trolley dedicat-ed-wire communication system in domestic coal mines.
