The trapped geothermal heat in the infinite rock mass through which mine tunnels are excavated is a great threat to the safety of personnel and mine operating equipment in deep underground hot mines. In order to lessen the temperature inside the tunnel, a considerable amount of energy is being...
Influences of Fibers on Expansive Shotcrete Mixture Consisting of Calcium Sulfoaluminate, Portland Cement, and Calcium SulfateDownload
Shotcrete is often used by the mining industry as rock support, tunnel lining, and concrete repair. However, cracking within shotcrete is common, which delays production schedules and increases maintenance costs. To reduce cracking, expansive shotcrete mixtures are often used. While several...
