The Effect of Pore Water Pressure on Response of Roadway in Soft Rock
Large numbers of roadways in soft rock have been used to meet the need of coal production in HM mine. Based on coupled fluid -solid theorem, numerical analysis for the stability of surrounding rock has been done with fast Lagrangian analysis of continua in three-dimension by considering the effect of pore water pressure on displacement laws, block state distribution. According to the numerical analysis of different pore water pressure, the results of effect of high pore pressure on deformation of roadway in soft rock have been obtained. The achieved results are successfully applied to guidance of the support of roadway in the soft rock in HM coal mine. Furthermore, the results would provide a theoretical basis for the support design of roadway in soft rock with high pore pressure.
