Electromagnetic compatibility requirements in underground coal mines

1 Scope

GB 48006-2026 is the Chinese national standard on requirements of electromagnetic compatibility in underground coal mine, in the field of mining and minerals. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 28 January 2026 by the State Administration for Market Regulation; Standardization Administration of China, and takes effect on 1 November 2026. Classification: ICS 73.100.99, CCS D98. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the electromagnetic compatibility requirements for electrical equipment in underground coal mines and describes the corresponding test methods. This document applies to the limit measurement of electromagnetic environment in underground coal mines, and to the measurement of operating frequencies in underground coal mines within the range of 0Hz to 400GHz. Electromagnetic compatibility design, manufacturing and inspection of electrical equipment and its downhole installation. This document covers the emission requirements for radio frequency interference in the 9kHz~6GHz frequency band. This document covers the immunity requirements for underground electrical equipment in coal mines operating in the frequency range of 0Hz to 400GHz.
