COMPOSITION AND PROCESS FOR STRENGTHENING AND SEALING GEOLOGICAL FORMATIONS AND STRATA IN MINING AND DEEP DRILLING

摘要

Geological formations and strata are strengthened, solidified, and sealed in mining and deep drilling by means of a Sorel cement mixture containing a small amount of a water soluble ammonium salt such as ammonium chloride. A small amount of an aminoplast may be added. The magnesium oxide component of the Sorel cement may have admixed thereto magnesia usta.
