| Abstract: | The paper introduces that fhrough observation of excited grund sound, the stress states of coal body under various conditions evaluated in the process of mining the isolated pillars at Cheng Zi colleiry.
The observed information of excited ground sound shows that bosed on the main frequency of the ground sound event, stress drop and time change of unloading range we can give a reasonable explanation for the experimental preventative measures used used in the past. |
