Abstract

The expandible, lost sealing plug (10) seals a borehole filled with pressurised liq. for rock consolidation in underground mines. It has a sealing portion (16) between an inlet(12) and an outlet head (14) in the form of an elastic hose expanded by the pressure against the hole wall, and enclosing a rigid spacer (38) between the heads. A passage (22,24) for the liq. passes through each head. These passages extend into the spacer end sections (80,82) to outlets (88,90), adjacent to the heads, between the sealing portion and the spacer.
