文摘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.
