Abstract EN
The rupture of the shaft lining caused by grouting has seriously undermined the safety in coal mining.
Based on BOTDR distributed optical fiber sensing technology, this paper studied the layout method of optical fiber sensors and the anomaly detection method of the deformation and obtained the evolution law of shaft deformation triggered by grouting.
The research results showed that the bonding problem of optical fiber sensors in damp environment could be effectively solved, by applying the binder consisting of sodium silicate and cement.
Through BOTDR-based deformation detection, the real-time deformation of the shaft lining caused by grouting was immediately spotted.
By comparing the respective strain of shaft lining deformation and concrete deformation, the risk range of shaft lining grouting was identified.
With the additional strain increment of the shaft lining triggered by each process of grouting, the saturated condition of grouting volume in strata was analyzed, providing an important technical insight into the field construction and the safety of the shaft lining.
