Zusammenfassung: | The invention provides a risk determination method, device and system for coal mine rock burst. The method comprises the steps of obtaining multiple pieces of index data of a target area, and classifying the multiple pieces of index data to obtain multiple types of index data; determining the weight of each type of index data by adopting an AHP algorithm; calculating a weighted average value of all the types of index data according to the plurality of weights to obtain a comprehensive score, and enabling the weights to be in one-to-one correspondence with the types of index data; and according to a size relationship between the comprehensive score and a threshold value, determining whether a rock burst phenomenon occurs in the target area. In the scheme, a rock burst risk determination scheme is provided, multiple index data which can cause the rock burst can be classified, the index data are all influence factors of the rock burst, analysis is carried out through the AHP algorithm, the index data are scored, |
