Introduction

Mining safety concerns all owners, developers, managers, and workers in all mining environments. Routine mining activities generate risks to personnel.

Particulate matter in the atmosphere is harmful to human health. Therefore, it is necessary to develop appropriate control measures to reduce operator exposure to particulate matter while operating equipment in the control room.

The risks associated with particulate matter in the atmosphere. As more and more countries implement air quality regulations in mining, construction, and industrial environments, equipment manufacturers are also...

There is a growing recognition of the need to establish standards and specifications for operator room design and performance. This document aims to clarify the basic requirements for operator room design.

The goal is to ensure that the control room can continuously maintain good air quality and reduce the concentration of inhalable particulate matter and carbon dioxide that are harmful to human health.

This document focuses on the following three aspects.

a) Design;

b) Performance testing of the air quality control system;

c) Maintenance and operation instructions for the control room.

Whether it is a new equipment or an existing old equipment control room, as long as it meets the requirements of this document, it can stably achieve air quality control performance.

The technical characteristics, design, and performance testing methods of the control room are universal; therefore, this document strives for broad applicability to meet the needs of fixed-type...

The need for mobile control rooms.

This document aims to protect the occupational health and safety of personnel working in the control room, primarily by setting parameters to determine air quality.

The effectiveness of the control system is crucial for solving air quality problems. Measures to control these air pollutants include. employing efficient air quality control systems.

Control system (simultaneously processes outside air and recirculated air), dilutes carbon dioxide concentration, regularly monitors air quality in the operating room, and in operation...

Effective maintenance should be carried out throughout the entire service life of the control room. Extensive research has been conducted and related results published on air quality control systems.

As a result, a rich knowledge system has been formed, which provides the basis for the formulation of this document (see references).

As shown in Figure 1, this document addresses the design, performance testing, and maintenance of the control room air quality control system from a full lifecycle perspective.

Standards have been established.

Mining Operation Room Air Quality Control System Performance requirements and test methods

1 Scope

This document specifies the performance and design requirements for the control room air quality control system and its monitoring devices. These design specifications are generally applicable.

It is not specific to any particular mining environment, but is designed to meet established requirements for pressure parameters, inhalable particulate matter concentration parameters, and carbon dioxide concentration parameters.

This document also specifies the test methods for evaluating the above parameters, provides operation and maintenance instructions, and outlines the operation of the air quality control system.

The integration proposed recommendations.

This document does not include information regarding hazardous gases and vapors that may be present in outdoor working environments.
