A Targeted Grouting and Water Blocking Method Based on Hydrological Tracer Testing and Its Engineering Applications

Hydrological tracer testing is an effective way to determine the law of recharge and the transport of groundwater. In karst collapse mine water treatment, the hydrological tracing test can determine information such as the runoff velocity and the pattern of underground runoff, so that targeted grout...
