First International Symposium on Mine Safety Science and Engineering Research on comprehensive early-warning technology of Coal and gas outburst

摘要

The paper proposed the principle and approach of comprehensive early warning of coal and gas outburst. Objectively existing outburst risk of working face, defects of outburst prevention measures and management are the main source of danger of coal and gas outburst. Based on the opinion, the integrated index system of outburst early warning is established. According to relevant regulations, standards, and actual mine condition, the rule base models of comprehensive early warning of outburst were established, and the warning degree system is divided into two major categories: the state and the trend. Implementation method of the warning system was studied, and the software, hardware architecture and computer systems were built. The onsite trials and applications indicate that the comprehensive early warning system of coal and gas outburst can realize the intelligent advance warning of hazards, improve the mine management level of outburst prevention, and secure the mine production safety.
