Research on the Lining Monitoring System of Mine Shaft in the Special Strata

摘要

The shaft lining in deep topsoil will be lead to fracture by the vertical additional force, which is caused by the bottom aquifer drainage settlement. Through the establishment of the shaft lining automatic monitoring system, the mechanical state of shaft can be effectively analyzed and the overall safety can be valuated. When monitoring data show that the shaft lining will be fractured, the rocks, management measures can be timely taken to prevent more damage by a ruptured shaft. In the process of ground grouting treatment to prevent shaft fracture, the monitoring data can be as shaft lining stability and grouting parameter adjustment basis, to ensure safety and grouting reinforcement effect.
