A causation mechanism for coal bursts during roadway development based on the major horizontal stress in coal:Very specific structural geology causing a localised loss of effective coal confinement and Newton’s second law

An assessment of coal pillar system stability criteria based on a mechanistic evaluation of the interaction between coal pillars and the overburden

引用

International Journal of Mining science and Technology 2017年第1期27卷 9-15页

作者： reed Guy Mctyer Kent Frith Russell Mine Advice Pry Ltd NewcastleNSW 2322Australia

Coal pillar design has historically assigned a factor of safety(Fo s) or stability factor(sF) according to their estimated strength and the assumed overburden load acting on them. Acceptable Fo s values have been assigned based on past mining experience or a statistical link between Fo s and probability of failure(Po F). Pillar width-to-height(w/h) ratio has long been established as having a material influence on both pillar strength and its potential failure mode. However, there has been significant disagreement on using both factor of safety(Fo s) and w/h as part of pillar system stability criterion, as compared to using Fo s in isolation. This paper will argue that there are valid technical reasons to bring w/h ratio into system stability criteria(other than its influence on pillar strength), as it is related to the post-failure stiffness of the pillar, as measured in situ, and its interaction with overburden stiffness. When overburden stiffness is also brought into pillar system stability considerations, two issues emerge. The first is the width-todepth(W/D) ratio of the panel and whether it is sub-critical or super-critical from a surface subsidence perspective. The second relates to a re-evaluation of pillar Fo s based on whether the pillar is in an elastic or non-elastic(i.e., post-yield) state in its as-designed condition, as this is relevant to maintaining overburden stiffness at the highest possible level. The significance of the model is the potential to maximise both reserve recovery and mining efficiencies without any discernible increase in geotechnical risk, particularly in thick seams and higher depth of cover mining situations. At a time when mining economics are, at best, marginal, removing potentially unnecessary design conservatism is of interest to all mine operators and is an important topic for discussion amongst the geotechnical community.

Poor maternal nutrition inhibits muscle development in ovine offspring

Journal of Animal science and Biotechnology 2015年第1期6卷 79-89页

作者： sarah A reed Joseline s Raja Maria L Hoffman steven A Zinn Kristen E Govoni Department of Animal science University of ConnecticutStorrsCT 06269USA

Background： Maternal over and restricted nutrition has negative consequences on the muscle of offspring by reducing muscle fiber number and altering regulators of muscle growth. To determine if over and restricted maternal nutrition affected muscle growth and gene fed 60%, 100% or 140% of National Research Council and protein expression in offspring, 36 pregnant ewes were requirements from d 31 ＋ 1,3 of gestation until parturition. Lambs from control-fed （CON）, restricted-fed （REs） or over-fed （OVER） ewes were necropsied within 1 d of birth （n = 18） or maintained on a control diet for 3 mo （n = ] 5）. semitendinosus muscle was collected for immunohistochemistry, and protein and gene expression analysis. Results： Compared with CON, muscle fiber cross-sectional area （CsA） increased in REs （58%） and OVER （47%） lambs at 1 d of age （P〈 0.01）; however at 3 mo, CsA decreased 15% and 17% compared with CON, respectively （P 〈 0.01）. Compared with CON, muscle lipid content was increased in OVER （212.4%） and REs （92.5%） at d 1 （P 〈 0.0001）. Muscle lipid content was increased 36.1% in OVER and decreased 23.6% in REs compared with CON at 3 mo （P 〈 0.0001）. At d 1, myostatin mRNA abundance in whole muscle tended to be greater in OVER （P = 0.07） than CON. Follistatin mRNA abundance increased in OVER （P = 0.04） and tended to increase in REs （P = 0.06） compared with CON at d 1. However, there was no difference in myostatin or follistatin protein expression （P 〉 0.3）. Phosphorylated Akt （ser473） was increased in REs at 3 mo compared with CON （P = 0.006）. Conclusions： In conclusion, maternal over and restricted nutrient intake alters muscle lipid content and growth of offspring, possibly through altered gene and protein expression.

Matrix Crack Detection by an Embedded Polarimetric sensor

引用

Journal of Materials science & Technology 2006年第2期22卷 220-224页

作者： H. Wang s.L. Ogin A.M. Thorne G. T.reed school-of Engineering University of Surrey Guildford Surrey GU2 5XH UK school of Electronic Engineering Information and Mathematics University of Surrey Guildford Surrey GU2 5XH UK

Polarimetric optical fibre sensors have been embedded within the 0° ply and close to the 0/90 interface of transparent cross-ply GFRP coupons. The laminate ply cracks may initiate and propagate across the coupon when the coupons were subjected to an increasing quasi-static load in a servo-hydraulic testing machine. Crack accumulation have been monitored using a long gauge-length extensometer. The response of the strain signal, the optical signal and the load signal to cracks at different positions in the coupon in relation to the extensometer and optical sensor positions have been acquired and compared by means of video images of the crack growth. The relationship between crack growth and sensor response was demonstrated. The displacement induced by a new transverse crack has been predicted and compared with experimental data.
