An Experimental Study on the Mechanical Properties and Expansion Characteristics of a Novel Self-Swelling Cartridge for Rock Breakage

The application of conventional soundless (or silent) chemical demolition agents (SCDAs) is complicated and it is easy for the agents to extrude from boreholes; it is also difficult to use it in wet or up-tilt boreholes, which limits their engineering application. In this paper, the components of conventional SCDAs are optimized and an innovative SCDA cartridge is presented, which is called self-swelling cartridge (SSC). Water absorption,...
