Preparation and application of multi-factor coupling evaluation software for coal mine rockburst hazard

In order to rationally evaluate the risk of coal mine rockburst, the technical disadvantages of traditional evaluation methods are overcome.The influencing factors of rock burst and the existing classification evaluation criteria of rock burst risk are studied.With MATLAB software for the programming language, using a graphical user interface(GUI), through the formulation of impact ground pressure hazard in coal mine multi-factor coupling evaluation software, with mining depth, the coal and rock structure, geological structure, strata spatial structure and coal pillar induced five factors as evaluation index, has realized the coal impact ground pressure hazard assessment and grading.Taking a coal mine in Shandong province as an example, the multi-factor coupling evaluation of rock burst risk was carried out on a working face of the mine by using the multi-factor coupling evaluation software.The results show that the working face has a moderate risk level of rock burst, and the risk area includes six general risk areas, three moderate risk areas and one high risk area.The software can accurately reflect the degree of coal mine rockburst risk, improve the operability and practicability of the existing evaluation methods, and improve the accuracy and scientific nature of the rockburst risk evaluation.
