摘要
Disclosed in the invention is a multi-information coupling prediction method of coal and gas outburst danger, which is achieved by establishing a multi-index coupling prediction model to detect indexes including original gas pressure of a coal layer, the original rock stress, the critical burst gas pressure of a coal sample, the mechanical performance of coal body, the exploit influence, the drilling cutting gas desorption index, the drilling cutting quantity index and the like, therefore to coupling predict the coal and gas outburst danger. By the multi-information coupling prediction method, the information of the coal and gas outburst danger can be fully complemented; the gas and crustal stress outburst danger prediction is carried out; the defects of insufficient complementation information of a single-index and inaccurate prediction are overcome; and the accuracy of the coal and gas outburst danger prediction is improved.
