国内金属矿山井下第一个国产元器件泄漏电缆移动通信系统,由梅山冶金公司铁矿和机电部22所研制成功。该系统应用泄漏电缆远距离有线传输和横向近距离无线传输相结合的技术,双向中继器串联组网,实现井下移动通信。通过井下200m运输巷道和采掘面400m泄漏电缆移动
Domestic metal mine downhole first domestic component leakage cable mobile communications system, by Meishan Metallurgical Company Iron and Mines Department 22 successfully developed. The system uses a combination of long-distance cable transmission and horizontal short-range wireless transmission of leaky cables and a bidirectional repeater series networking to realize underground mobile communication. Through the underground 200m roadway and mining face 400m leak cable move
