Abstract: In order to prevent coal and gas outburst accidents and improve mine security capacity, gas geological dynamic analysis and gas emission real-time pre-warning system was built in Xinyuan Company. Gas geology spatial database was built based on statistics and analysis of mine gas geological data. The main control factors affecting gas occurrence were summarized using dynamic analysis technique, and gas parameter isolines were drawn automatically. Outburst dangerous areas were compartmentalized, and outburst dangerous working faces were specially concerned. Gas emission features and pre-warning indicators were researched. Connected with gas monitoring system seamlessly, non-contact continuous pre-warning was achieved.
