摘　　要：针对地质力学模型试验中围岩断裂缝测试技术要求,提出采用断裂丝测试围岩断裂缝的方案,并对断裂丝材料进行筛选。通过对比试验,最后选择石墨型线材,该材料基本上能与模型介质的断裂缝同步发生,满足试验要求。将该材料应用到淮南煤矿中,得到围岩断裂缝的发生、发展过程。本技术可为类似试验中的断裂缝测试提供借鉴。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 development processes of surrounding rock fissures testing in similar experiments. is applied to the Huainan coal mine and the occurrence and are obtained. This technique can provide reference for fissuretesting in similar experiments.
