Slope stability is of significant importance for sustainable development in mining, civil-engineering, and urban planning. This paper attempted to assess the conditions road cut debris slopes along National Highway-7 (NH-7), Uttarakhand, India. The engineering parameters slope forming materials other inputs used analysis were evaluated based on different geotechnical tests such as direct shear strength, density test, rock hardness tests, particle size analysis, Atterberg limits, XRD finer...
Rock mass in open cast mines is generally fragmented by blasting. The sudden release of explosive energy not only fragments rock but also generates undesirable nuisances such as ground vibrations, fly rock, dust, toxic fumes, back break, air overpressure (AOp) etc. AOp can vibrate civil engineering structures, shatter glass windows and doors, adversely affect living quality. present study strives to develop a reliable artificial intelligence model (AI) for predicting some Indian mines. For...
Slope stability assessment is essential for safe and sustainable development widely applied in mining, civil, environmental engineering projects around the world. This study aimed to conduct a analysis of selected Himalayan road cut slope from two different sections, named sections (A) (B). The strength reduction factor (SRF) based on finite element method was used simulate using Phase2 software. A mesh pattern six node triangle elements during numerical simulation. Mohr-Coulomb parameters...
Regression analysis is commonly used to predict the compressive strength of soil-based materials reduce time and cost construction projects. This study presents results multivariate regression on prediction modulus rupture specific energy cement-stabilised earth bricks reinforced with bamboo cellulose fibres as a function fibre percentage, curing temperature time. Statistical modelling carried out experimental data four-point bending test clay brick stabilised 10 wt% Ordinary Portland Cement...
The production of cellulose in the nano-scale size and their application as a reinforcement construction materials have gained increasing attention due to unique properties, such high tensile strength modulus elasticity, large specific surface area. This study aimed evaluate mechanical, physical thermal behaviour extruded earth-based matrix reinforced with 0.1%, 0.3%, 0.5%wt. nanofibrillated (NFC). results shown that mechanical nanofibrillation process fibre improves its stability. Their...
Ground vibration induced by rock blasting is an unavoidable effect that may generate severe damages to structures and living communities. Peak particle velocity (PPV) the key predictor for ground vibration. This study aims develop a model predict PPV in opencast mines. Two machine-learning techniques, including multivariate adaptive regression splines (MARS) classification tree (CART), which are easy implement field engineers, were investigated. The models developed using record of 1001 real...
In this work, mineralogical and physical characterization of low-grade tantalum-tin ore-samples from Ntunga Kamonyi Rwanda were carried out using various techniques. The classified as non-radioactive ores they contained less than 0.1% Ta2O5 Nb2O5, the percentage radioactive oxides below critical value 0.5%. characteristic elements associated with tantalum detected quantified by Inductively Coupled Plasma-Optical Emission Spectroscopy expressed for their natural occurrence included Ta2O5,...
In this work, an experimental investigation on the use of eggshell powder from waste eggshells as alternative source bio-filler and flux to enhance technological properties fired clay bricks were carried out. Four different batch compositions formed with a replacing clay-soil up 15 wt.%. The prepared by casting method at 800, 900, 1000 °C heating rate 8 °C/min for 120 minutes. raw materials produced characterized SEM/EDS, XRF, XRD, respectively. Besides, (eg. water absorption, apparent...
Abstract Construction and mining industries around the globe have been criticized for production of enormous solid wastes that potential environmental impacts. Therefore, this study presents a feasible approach to recover utilize granite micronized stones waste eco-friendly bricks. This research work, aimed at substituting natural clay with powder produce value-added bricks pronounced physical–mechanical properties. The were crushed ground obtain fine sample. Thereafter, different batch...
The nature of gold (Au) ore deposits plays an essential role in determining the best recovery method as alternative to cyanidation, considering environmental concerns. Thiourea (Tu) leaching is lixiviant for treating sulfide ores and concentrates. present study investigated behavior Au from concentrates obtained Cripple Creek site (Newmont operated mine) using acidified thiourea solution. containing pyrite, K-feldspar, quartz, gypsum major minerals were roasted before break down complex...
