多因素综合分析法在煤与瓦斯突出区域预测中的应用

Application of Multi-factor Comprehensive Analysis Method in the Regional Prediction of Coal and Gas Outburst

通过多因素综合分析法对影响煤与瓦斯突出的各因素进行细致的分析,可以有效避免单一因素易造成误判的缺点,提高突出区域预测的准确性。以丁集煤矿东一采区13-1煤层为例,运用多因素综合分析法对该煤层进行了突出区域划分,确定了突出危险区和非突出危险区。

Abstract. Through meticulous analysis of various factors affecting the coal and gas outburst by the multi - factor comprehensive analysis method, the defects of misjudgment caused by single factor can be effectively avoided, which improves the accuracy of regional predic- tion. Taking No. 13 - 1 coal seam in the east NO. 1 mining area of Dingji coal mine as an example, the coal seam outburst areas are di- vieded by using multi - factor comprehensive analysis method, which determines the danger zone of outburst and non - outburst.
