Abstract EN
Rock burst is a common mine disaster often accompanied with casualties and property damage.
In order to effectively predict and prevent the rock burst occurrence, an effective and accurate method for predicting rock burst is necessary.
This paper first establishes the relationship between the drilling cuttings and the releasable elastic deformation energy.
However, the traditional drilling cutting method has the defect that the drilling depth cannot reach the stress concentration area and the drilling cuttings cannot accurately reflect the internal stress variation in the deep part of coal body.
So, an improved drill cutting method is presented to make up for these defects.
Finally, the combined monitoring method based on the improved drilling cutting method and the microseismic monitoring method is established.
It not only overcomes the limitations of a single prediction method but also effectively utilizes the advantages of improved drilling cutting method and the microseismic monitoring method.
And this combined monitoring method is applied to the No.
3302 coalface of Xingcun Coal Mine.
The obtained results indicate that the combined monitoring method can improve the prediction capabilities of the rock burst and provide novel insights for preventing the rock burst occurrence.
