Rock strength, specifically the uniaxial compressive strength (UCS), is a critical parameter mostly used in effective and sustainable design of tunnels other engineering structures. This determined using direct indirect methods. The methods involve acquiring an NX core sample sophisticated laboratory procedures to determine UCS. However, are time-consuming, expensive, can yield uncertain results due presence any flaws or discontinuities sample. Therefore, most researchers prefer for...
The geological strength index (GSI) is one of the most exceptional rock mass classification system which used to evaluate very weak and highly jointed by different approaches related geomechanical properties including generalized Hoek & Brown constants, deformation modulus, properties, Poisson’s ratio for an appropriate design tunnels, caverns, other engineering structures. distinctiveness this over rating (RMR), Q‐system, empirical methods as follows: it utilized field observations,...
In recovering additional oil from extensively fractured reservoirs, cyclic water pulsing has been found helpful. Cyclic gas can be even more effective. This study indicates that by judiciously combining the two methods some of limitations each could overcome and recovery amounting to as much 25 percent pore space contacted achieved. Introduction Low-permeability reservoirs are dissected a network interconnected fractures, solution channels, vugs generally not suited for waterflooding or...
The rock mass deformation modulus (Em) is an essential input parameter in numerical modeling for assessing the behavior required sustainable design of engineering structures. situ methods determining this are costly and time consuming. Their results may not be reliable due to presence various natures joints following difficult field testing procedures. Therefore, it imperative predict using alternate methods. In research, four different predictive models were developed, i.e., one statistical...
Numerous researchers have examined the co-current flow of oil-water and aqueous solutions containing polymers surfactants in thin gaps for oil recovery. While some focused on charges forces at interfaces oil-surfactant during flow. The study structures, interface behavior, relative permeabilities phases surfactant through has been less explored. For first time, this research aims to comprehensively investigate a gap (Hele-Shaw cell) with particular focus impact sodium dodecyl sulfate (SDS)....
The aim of the research work was to optimize cyanidation leaching parameters for maximum extraction gold and silver from complex ore Shoughur area district Chitral, Khyber Pakhtunkhwa on laboratory scale testing. carried out into two parts. In first part like grinding time, dosage pH, sodium cyanide (NaCN) lime Ca (OH)2 were optimized. samples were subjected differential time varying 20 35 minutes, pH slurry adjusted 9 11 by adding 0.5 1.5 gm/kg , NaCN varies from 0.1% 0.02 % 0 40 hours....
Discussion of this paper is invited. Three copied any discussion should be sent to the Netherland Section Society Petroleum Engineers, P.O. Box 228, The Hague, Netherlands. Such may presented at above meeting and, with paper, considered for publication in one two SPE magazines. Abstract Laboratory investigation has been made a novel approach designed improve displacement efficiency waterflood. This consists injecting slurry finely divided solid particles water, linear advance rates 3 20...

Nature has blessed Pakistan with huge reserves of dimension stone that are mostly extracted through conventional mining methods. Different mechanized techniques have been tested and some give propitious results but failed to get popularity in the sector Pakistan. One such attempt is made this work a non-conventional method expansive mortar (EM) introduce into sector, reduce waste cracks produced during (drilling blasting). The proclaim efficiently reduced production increased productivity....
The design of a stable slope in rock mass environment is quite complicated job due to the anisotropic behaviour mass. In this research work, cut slopes at Swat motorway weakest schist numerically analyzed by shear strength reduction (SSR) approach using Finite Element-based 2D RS2 software. divided into two cases according nature rock. Each case stabilization methods: 1) changing characteristics 2) support system installation based on Mohr-Coulomb (MCC) and Generalized Hoek Brown (GHB)...
Despite the slope stability measures, rock falls are witnessed at section KM-37 of Swat motorway (M-16), Khyber Pakhtunkhwa, Pakistan. The geotechnical data analysis site reveals that although chances plane/slope failures reduced from 43% to 23% with help existing design, still there possibilities fall sight, which has also been during field visits. hazards assessed through tests and simulation, significant stabilization measures suggested. conducted, then using obtained, simulation is...
