Scope

NB/T 10722-2021 is the English-translated version of 矿井漏泄通信系统通用技术条件.

NB/T 10722-2021 sets general technical conditions for leaky feeder communication systems in underground mines, in which radio waves are carried along leaky cables linked to base stations that exchange, connect, control and manage information.

It classifies the systems and specifies their technical requirements, test methods and inspection rules. Radio performance is measured with the FM transmitter and receiver methods of GB/T 12192 and GB/T 12193 and assessed against the leaky cable system specification GB/T 15875.

Explosion protection follows the GB 3836 series, including encapsulation to GB 3836.9, and immunity is tested to GB/T 17626.3-2016, 17626.4-2018 and 17626.5-2019. Issued on 16 November 2021, it has applied since 16 February 2022.
