Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0028] In the process of coal mining, the load sources that induce rock burst can be divided into three types according to the spatial scope: long-distance large-scale, short-distance small-scale, and in-situ load sources in the start-up area. The coal mine rock burst split-source comprehensive early warning method of the present invention proceeds from the perspective of rock burst occurrence mechanism, and performs separate source monitoring and early warning for different load sources that induce rock burst in different spatial ranges.
[0029] figure 1 It is a method flowchart of the present invention, as shown in the figure, the coal mine rockburst sub-source comprehensive early warning method of the present invention comprises the following steps:
[0030] S10: Arrange and install microseismic monitoring system, ground sound monitoring ...
