The longwall mining method is one of the most applied methods in extracting low-inclined to high-inclined coal seams. Selection of the most suitable extraction equipment is very important in the economical, safety, and productivity aspects of mining operations. There are a lot of parameters affecting the selection of an extraction equipment in mechanized longwall mining in steeply inclined coal...

Variations in rock mass properties are well-established mechanics and underground mining. The literature is replete with methods of assessing them determining values that used design or numerical analysis. In this paper, a simplified 3D model constructed for tabular orebody the Canadian Shield instability quantified using ”brittle shear ratio” criterion to calculate volume at risk. A 1-4-7 stop...

This study aims to quantify effects of hanging-wall/footwall fault parameters on dynamic responses base-isolated and base-fixed ancient timber buildings. Finite element models a real building with without isolation technology are first built verified by comparison existing studies. Fitting analysis three typical models, Abrahamson-Silva-Kamai, Campbell-Bozorgnia Chiou-Youngs as well 622 recorde...

PURPOSE A framework for multidimensional assessment of patient room configurations is presented. Twenty-three issues are considered and categorized under six domains of assessment: (1) patient safety, (2) staff efficiency, (3) circulation, (4) infection control, (5) patient considerations, and (6) family amenities. Use of the framework to rank issues by importance and assess six alternative pat...

We examine the tectonic geomorphology of La Sila, Calabria, southern Italy, a high-standing (1500 m) plateau surrounded by crustal extension, with map, DEM, and field data. These data are used to constrain a simple geodynamic model that describes short-wavelength deformation of the plateau rim. Topographic metrics including drainage patterns, river longitudinal profiles, and swath profiles are ...

The Yadong cross structure (YCS), occurring at ~89°30' east longitude in the Himalaya, is the largest across-strike discontinuity in the geologic structure and topography of the High Himalaya between the Himalayan syntaxes. It is manifest by a plan view left offset of the topographic crest of the range and a coincident, apparent, left strike offset of the South Tibetan Detachment System (STDS) ...

[1] The Wasatch Mountains are often cited as an example of normal fault growth and footwall flexure. They represent a tilted footwall at the edge of the Basin and Range extensional province, a major rift basin. Thus understanding the detailed spatial and elevation changes in coupled thermochronometer data, and how these changes can be interpreted, may aid in the analysis of thermochronometer da...

An assemblage of hydrous, Cl-bearing alteration-induced minerals is present within 150 m of footwall-style Cu–Ni–PGE sulfide mineralization hosted by the Sudbury Breccia at the Fraser Copper zone, Fraser mine, Onaping–Levack area, Ontario. The pyroxene hornfels to hornblende hornfels contact-metamorphic aureole of the Sudbury Igneous Complex (SIC) contains less than 15 modal % hydroxysilicates....
