Accurately determining rock elastic modulus (EM) and uniaxial compressive strength (UCS) using laboratory methods requires considerable time cost. Hence, the development of models for estimating mechanical properties is a very attractive alternative. The current research was conducted to predict UCS EM sandstone rocks quartz%, feldspar%, fragments%, compressional wave velocity (PW), Schmidt har...

The uniaxial compressive strength (UCS) and Youngs’ modulus (E) of rock are important parameters required during design stability analysis mining geotechnical structures. There is correlation between UCS E rock, the proper estimation such for reliable engineering analysis. However, limited quantity data pairs often available most project sites makes it difficult to estimate E. This study addres...

The thinning of tailings gradation during ore processing leads to a sizeable fall in the strength cementitious paste backfill (CPB), increases operational risks, and encourages researchers use alternative economic products. This study aims increase performance by improving CPB’s while cutting costs reducing sum binder employed per unit volume. An evolution slump/strength/structural properties s...

Abstract Laboratory tests were conducted on sugarcane bagasse ash treated sewage sludge-soil mixture with 5%, 10% and 30% to assess its strength behaviour. Unconfined compressive (UCS) was performed observed influence of content (BAC), curing time, water value UCS axial strain. Soil sample prepared using standard proctor at 60% optimum content. Results recorded reached peaked 20% BAC then dropp...

This paper provides physical and chemical performances of mass stabilised organic and inorganic contaminated site soils using a new group of MgO-bearing binders over 3 years and evaluated the time-dependent performance during the 3 years. This study took place at a contaminated site in Castleford, UK in 2011, where MgO, ground granulated blastfurnace slag (GGBS) and Portland cement (PC) were mi...

Cemented tailings backfill (CTB), prepared by a mixture of tailings, binder, and water in certain proportion, is widely applied to mines worldwide for ground support disposal. The prediction the mechanical properties CTB during whole consolidation process great practical importance. objective this paper focuses on investigation performance based ultrasonic pulse velocity (UPV) method. samples w...
