The Application of Cementation in Mining

THE first application of the cementation process took place in the year 1864, according to H. Standish BaU, when a break in the brickwork lining at a depth of 270', in one of the Rhine Preussen pits near Homburg, was sealed by running in milk of cement from the surface by means of a small hand pump. At about th e same time Monsieur Portier adopted the method in F rance for repairing breaks in shaft lining. Figure 1 is descriptive of the Portier system and is of interest when compared with modern practice. During the next thirty years numerous attempts were made to improve the process ; the general method used in sinking being to put clown bore holes outside the pe ri meter of the shaft for the purposes of inj ection.
