  This evaluates the load supporting characteristics of grout columns used as point supports for mine subsidence abatement. The cone-shaped columns were constructed with sodium silicate and cementitious grout in both wet and dry environments. The scope of work included the testing of seven full-scale grout columns in the Bureau's Mine Roof Simulator (MRS) from which the load-deformation and failure characteristics were determined.
