Introduction

1. Background of Standard Formulation and Analysis of Technology Evolution

The main background of the revision of this standard is to meet the needs of safe production in the coal industry, combining the latest technology and engineering practice experience. New chapters such as mine pressure monitoring and geological survey equipment, and water exploration and drainage equipment have been added, and some outdated content has been updated.

Standard dimensions Original content New additions/adjustments in the revised version
Ventilation equipment Basic ventilation detection equipment Increase online monitoring system requirements and improve the level of intelligence
Gas prevention and control Basic burst prevention equipment New real-time diagnosis and early warning system and acoustic emission monitoring equipment
Geological survey Traditional geophysical methods Introduce microseismic monitoring and positioning technology to improve accuracy

2. Core equipment and practical applications

online ventilation monitoring system has significantly improved the ventilation efficiency of mines, especially in large and medium-sized mines, where its use can monitor key parameters such as wind speed and air pressure in real time.

Actual application case: Equipment upgrade of a high-gas mine

The mine effectively reduced the gas accident rate by deploying a new gas extraction pipeline gas parameter measuring instrument and coal seam gas pressure measuring device. After the equipment was updated, the monitoring accuracy was improved by 15% and the response time was shortened to 1/3 of the original.

3. Implementation suggestions

  • Gradually replace old equipment and give priority to upgrading safety protection and gas prevention and control equipment
  • Strengthen the construction of mine pressure monitoring system and improve prediction and early warning capabilities
  • Train professionals to ensure the correct use and maintenance of new equipment
