The purpose of this work is the calculation of the optimal parameters involved with advanced drilling of gas-draining holes. These holes are made to floor entryways and provide an efficiency test for floor degas extractions, like the AB bed at the Uralkali’s Berizniki Ore Development Unit No 2 and Unit No 4 (Mine 2 and Mine 4). Current conditi...
View ArticleThe pozzolanic reactions, responsible for the resistance of soil-lime blends, are endothermic. As such, increasing the curing temperature in turn increases the strength of lime-stabilized soil. Recent research has shown that there is a maximum limit to the resistance of a specimen, based on its curing time. This study aims to predict the maximum tensile...
View ArticleThe dynamic cone penetrometer (DCP) is a widely used in-situ device to determine the engineering properties of soils. This paper reports a meta-analysis of laboratory calibration studies to establish a relationship between the rate of penetration and relative density for sands. Fourteen (14) different sands from different geographic and geological setti...
