The mine geostress
measurement is the indispensable key to safe and efficient production of the
mine. Currently, stress relief method, hydraulic fracturing method and acoustic
emission method are widely used in mine geostress test fields. As deficiencies
of the above several methods, the author designed a detailed borehole acoustic
program for the tectonic fault conditions of a mine in Huainan, and got
geostress parameter values according to the combination of site measured
velocity values and laboratory tests.
