Abstract: In the underground construction roadway, the use of monitoring technology can predict no-working part of deformation of surrounding rock, the role of roadway deformation monitoring and stability supporting can not be ignored.This paper studies the monitoring method of underground roadway site, analyses the monitor content that must be measured, recommends a complete monitoring program and rock failure warning mechanism should be established to monitoring the trends of roadway deformation.It is a certain guiding significance to technology of monitoring underground construction roadway.
