Study on mechanical bebavior of epoxy bonded bolt system and bolt bearing characteristic in coal mine roadway
Abstract：Boh or cable supporting technology which is active supporting method to control the surrounding rock stabil- ity has been widely applied in underground coal mining in China. Based on the complexity of surrounding rock, princi- ples of bolt supporting have not yet common and completely understood, the bolt supporting need more study on the an- chorage mechanism, interactive relationship with the surrounding rock, stress distribution along the embedded direc- tion, bolt bearing characteristic and etc. This study took epoxy boned bolt system and bolt supported in coal mine road- way as research back ground, applied theoretical analysis, numerical simulation ,field measurement, laboratory test and engineering practice to explore the mechanical behavior of epoxy bonded bolt system and bolt bearing characteristic. The following findings were made：
