basic method and general situation of discontinuity surface mapping are summarized. Combined geodesic discontinuity surface parameters in the fields
a mapping method based on mechanics mechanism is put forward on the basis of considering mechanics mechanism of rock fracture. The technology is applied to forecast of overbreak in jointed rock masses openings. The veracity of the result will be tested by an engineering example. The result shows that discontinuity surface mapping considering mechanics mechanism of rock fracture can reflect the configuration of discontinuity and forecast properly overbreak in jointed rock masses openings.
