[0037] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0038] Please refer to figure 1 As shown, the Bayesian method-based dynamic-static coupling evaluation method for coal mine rock burst risk provided by the present invention comprises the following steps:
[0039] S1. The data received by the microseismic sensor and drilling stress sensor installed in the well are transmitted and stored to the monitoring system through the data transmission device, and the dynamic index parameter data with time series characteristics are obtained; by analyzing the database types of each monitoring system Translate the code, and then write the interface to read the data of the database in real time, and integrate and analyze the data of multiple monitoring systems.
[0040] S2. Carry out comprehensive index eval...
