Abstract

A method of blocking off a mine gallery, especially where there is water seeping through, uses a portion (31) which is the same shape as the contour of the gallery but smaller. The partition is anchored to the face (30) by a set of securing straps (33) around its periphery of the front and rear. The periphery may have a channel (38) around it, with the open side towards the face. Into this channel is inserted a hollow rubber ring (39) which is then inflated to form a tight seal all round. The face does not required treatment or cladding. Two closures of this type may be spaced apart to form a lock between them, each incorporating access doors. Each door has a wicket gate which can be opened so as to equalise the pressure on opposite sides of the lock.
