Economics of a hydraulic hammer for forest road construction in a mountainous area

open access: yesJournal of Forest Science, 2011
This research deals with productivity and cost of rock disintegration and side casting of materials with the use of a hydraulic hammer mounted on a PC 220 Komatsu crawler excavator, which is used on rocky slopes of Hyrcanian forests of Iran. A continuing

Evaluation of slope failure potential in forest roads (Case study: 46th watershed, North of Iran) [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2015
Forest road networks are the essential bases of modern and sustainable production within Hyrcanian forests of Iran. In most mountainous areas, the slope failures are often caused by the construction of forest road on steep terrains.

Pomeron with a Running Coupling Constant: Intercept and Slope [PDF]

open access: yes, 1994
The equation for two reggeized gluons with a running QCD coupling constant, proposed earlier on the basis of the bootstrap condition, is investigated by the variational technique in the vacuum channel.

Physical modeling of slope failure during slope cutting work

open access: yesDoboku Gakkai Ronbunshuu C, 2009
Full-scale slope model tests and centrifuge model tests were conducted to examine the mechanism of slope failure during slope cutting works. It was found that local slope failure was observed before complete slope failure and this mechanism was consistent with previous slope failure accidents. The horizontal and vertical movements of the slope could be

Analysis of Excavation Stability and Reinforcement Treatment of the Cutting Slope under the Influence of Old Goaf

open access: yesApplied Sciences, 2022
To analyze the excavation stability and reasonable reinforcement measures of cutting slope with a goaf collapsed roadway and collapsed mining face, the finite element software Midas GTS NX was used to model and analyze the change in the slope stability ...

Coupled hydro-mechanical modelling of a 1995 Hong Kong landslide [PDF]

open access: yesE3S Web of Conferences, 2020
The paper deals with the modelling of the instability mechanism induced by rainfall in an unsaturated cut-slope. A large-sized landslide occurred in 1995 in Hong Kong (the so-called “Fei Tsui Road landslide”).

LiBeB Production and Associated Astrophysical Sites [PDF]

open access: yes, 2000
The various modes of spallative LiBeB production are summarized, and classified according to their dependence or independence on the abundance of medium heavy elements (CNO) illustrated by that of oxygen in the interstellar medium.

Natural revegetation of forest road slopes

open access: yesGlasnik Šumarskog Fakulteta Univerziteta u Banjoj Luci, 2010
The revegetation of forest road slopes depends on many factors. For this research work we studied 170 transverse profi les of forest road in Menina mountain (Alpine region, northern Slovenia) on hard, mainly limy ground surface.

Methods applied in Australian industry to evaluate coal mine slope stability

open access: yesInternational Journal of Mining Science and Technology, 2020
Strata failure is a principal hazard in open cut coal mining as it has the potential to cause multiple fatalities. Prior to the excavation of any slope, a geotechnical assessment should review the likely slope performance, including the risk of slope ...
