GB/T 47115-2026 Mining—Air quality control systems for operator enclosures—Performance requirements and test methods

Scope

This document specifies the performance and design requirements for the air quality control system and its monitoring devices in the operating room. These design specifications are universal and not targeted at specific mining environments. They are designed to meet the established pressure parameters, respirable particulate matter concentration parameters, and carbon dioxide concentration parameters requirements. This document also stipulates the testing methods for evaluating the above parameters and provides operating and maintenance instructions, while making recommendations for the operational integration of the air quality control system. This document does not include content related to harmful gases and vapors that may exist in the working environment outside the operating room.
