Abstract The geomechanical characteristics of a drill formation are uncontrollable factors that crucial to determining the optimal controllable parameters for drilling operation. In present study, data collected in wells drilled Marun oilfield southwestern Iran were used develop adaptive network-based fuzzy inference system (ANFIS) models parameters. specific energy (DSE) was calculated using s...

in advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. the gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (edz) above the gate roadway and 2) loading effect due to the caving zone (cz) above the longwall w...

the cold climate is a favorable parameter for the development of tension cracks and decrease of rock brittleness. therefore, this paper attempts to investigate the hamekasi porous limestone in order to predict the brittleness indices during freeze-thaw cycles. the freeze–thaw test was executed for one cycle including 16 h of freezing, and 8 h of thawing. the geo mechanical properties and brittl...

Shallow bedrock strength controls both landslide hazard and the rate form of erosion, yet regional patterns in near-surface mechanical properties are rarely known quantitatively due to challenge collecting situ measurements. Here we present seismic geomechanical characterizations shallow subsurface across central Himalayan Range Nepal. By pairing widely distributed 1D shear wave velocity survey...

Estimating porous media properties is a vital component of geosciences and the physics media. Until now, imaging techniques have focused on methodologies to match image-derived flows or geomechanical parameters with experimentally identified values. Less emphasis has been placed compromise between image processing consequences topological morphological characteristics computed such as permeabil...
