Abstract：Based on the technical requirements of surrounding rock fissure testing in geomechanical model test，a fissure testing scheme with fracture wire is put forward；and the fracture wire materials are sifted. Through contrast test，graphite wire is chosen finally. This material can basically crack synchronously with model medium and satisfy the test requirements. The graphite wire is applied to the Huainan coal mine；and the occurrence and development processes of surrounding rock fissures are obtained. This technique can provide reference for fissure testing in similar experiments.
