| Abstract: | Taking Linhuan Coal Mine in Huaibei City as an engineering example and considering various influential factors of the deformation of surrounding rock of deep roadway,the calculation models of deep inclined roadway of Linhuan Coal Mine are established through the field observation,research,sampling and laboratory measurement of coal rock’s mechanical parameters.By using the finite element analysis software ANSYS,the deformation characteristics of roadway under the influence of soft rock are studied.The coupling support theory suitable for the surrounding rock deformation control of soft rock roadway is discussed,and based on this theory and the stress damage characteristics of soft rock roadway,the optimization design of soft rock support of Linhuan Coal Mine is presented.The numerical simulation of the effect of the support design is performed,and the results are instructive for the continuative field engineering experiment. |
