| Abstract: | Preliminary experimental studies are conducted on such mechanics as com-pressive strength, shear strength and deformational characteristics of flying ash in place of sand in shotcreting. Analysis is made of the mechanism of the flying ash in the process. Upon this basis, the conditions for the use of flying ash in underground shotcreting and the optimum preparation recipe are proposed. |
