Grout head and method for suppresssing leaks at rock faces, in mines, mining and in circumstances requiring sealing of cracks as required to suppress leaking

A Grout Head Forming a Leak Suppression Apparatus (100) and the Method of Use comprising a grout head having a base plate including a circular flange (110) having a top side 111 and a bottom side (113) and;

• the top side (111) having a top outer edge (112) and the bottom side (113) having a bottom outer edge (114) and;
• the flange (110) having a flange thickness (116) and;
• the circular flange (110) having a center (122) and a flange aperture (117) concentrically positioned in the flange (110);
• the flange aperture (117) having a flange aperture diameter (118), and the flange having a flange outer diameter (120);
• and
• a pipe (130) having a pipe outer surface (132) and a pipe inner surface (134);
• and the pipe (130) having a pipe wall (131);
• the pipe wall (131) having a pipe wall thickness (133);
• and
• the pipe (130) has a pipe inner diameter (136), a pipe outer diameter (138), a pipe outer circumference (134) and a pipe inner circumference (135), a pipe first end (137) and a pipe second end (139);
• the pipe (130) concentrically contacts the flange (110) at the flange bottom side (113);
• and
• the pipe inner diameter (136) and the pipe outer diameter (138) are larger than the flange aperture diameter (118) and are smaller than the flange outer diameter (120);
• the flange (110) and the pipe (130) are interconnected by permanent affixing means between the flange bottom side (113) and the pipe first end (137) at either or both the pipe outer circumference (134) or pipe inner circumference (135);
• and the flange (110) and the pipe (130) are composed of a rigid material including metals and plastics;
• and
• the pipe (130) having a length (129) and, the pipe (130), distal from the flange bottom side (113), having pipe connection means (140);
• and the flange (110) and flange aperture (117) and the pipe (130) are sized to receive a rock bolt known in the mining industry.
