Abstract:
On the basis of analyzing the influence of surrounding rock strength,structural surface and strata inclined angle on hollowinclusion stress relief method,it was put forward that applying information in detection borehole to selecting measurement layer.By constructing detection borehole near measurement point,measurement borehole parameters could be designed considering surrounding rock structure detection and strength test result.This method could largely improve measurement’s success rate.Underground application process and measurement effect was introduced and it was put forward that the intersection angle between axial line of borehole and layer plane should be 30 ~60°.
