Hierarchic Analysis Method to Evaluate Rock Burst Risk

Table 22

Verification of the model evaluation.

Mine ID	Mining depth	Mechanical characteristics of coal and rock	Geological structure	Coal thickness	Burst tendency of coal rock	Roof Control	Pressure release	Degree of production concentration	Rings of coal burst	Investment	Prevention measures	Training	Comprehensive index	Model results	Actual grade	Contrast result
1	6	4	2	2	4	2	2	6	2	2	4	2	3.2411	Level I	Micro-impact	Coincidence
