摘要

This paper presents case histories of grouting water-bearing fractured rock during driving of drifts in coal mines in Ukraine and the elimination of sudden inrush of water from large faulted zones in long Pin Lin Tunnel in Taiwan.In order to provide safe excavation of drifts and tunnels through water-bearing faulted zones and fractured rock the Ukrainian Donbas Special Grouting company (former STG Co.) implemented the new High Ben-tonite-Based Grouting Technology.
