Method and device for dividing outburst dangerous area based on gas-stress quantitative coupling

The invention relates to the technical field of coal and gas outburst dangerous area division, in particular to an outburst dangerous area division method and device based on gas-stress quantitative coupling, and the method comprises the steps: extracting coal seam gas data, and drawing a coal seam gas pressure distribution diagram; simulating coal seam stress field distribution of a full mining area scale according to mining area geologic features, and extracting coal seam stress gray value data from the simulated stress distribution diagram; respectively applying an analytic hierarchy process and an entropy weight method to determine subjective weights and objective weights of two indexes of coal seam gas pressure and coal seam stress, and comprehensively obtaining a comprehensive weight; coal seam gas pressure and coal seam stress distribution are coupled, a comprehensive index reflecting outburst danger is calculated, and the outburst danger is partitioned. According to the method, the two factors of coal
