1Optimization and application of blasting parameters based on the 'pushing-wall' mechanism显示文摘The large structure parameter of a sublevel caving method was used in Beiminghe iron mine.The ores were generally lower than the medium hardness and easy to be drilled and blasted.However,the questions of boulder yield,'pushing-wall' accident rate,and brow damage rate were not effectively controlled in practical blasting.The model test of a similar material shows that the charge concentration of bottom blastholes in the sector is too high;the pushing wall is the fundamental reason for the poor blasting effect.One of the main methods to adjust the explosive distribution is to increase the length of charged blastholes.Therefore,the field tests with respect to increasing the length of uncharged blastholes were made in 12# stope of 95 subsection and 6# stope of Beiminghe iron mine.This paper took the test result of 12# stope as an example to analyze the impact of charge structure on blasting effect and design an appropriate blasting parameter that is to similar to No.12 stope.Feng-yu Ren Thierno Amadou Mouctar Sow Rong-xing He Xin-rui Liu 2012International Journal of Minerals,Metallurgy and Materials2012,19,10:11
2北洺河铁矿改进装药结构试验研究显示文摘北洺河铁矿采用大结构参数无底柱分段崩落法开采,多年来大块率高、爆破隔墙事故与眉线破坏等爆破问题,一直没有得到很好解决。通过对扇形炮孔爆破机理的分析得出,形成推墙现象的主要原因,是扇形面内炮孔过于密集。以减小扇面炮孔的密度,将炮孔爆破的主导方向调整到抵抗线方向为出发点,进行了改进装药结构的现场试验,通过优化装药结构,改进了爆破效果。任凤玉 何荣兴 Thierno Amadou Mouctar Sow 李爱国 白伟现 2011金属矿山2011,40,2:9
3弓长岭井下矿采准巷道破坏形式及其支护技术研究显示文摘弓长岭井下矿中央区开采急倾斜中厚矿体,随着采深的增大,采准工程出现地压显现的部位增多、规模逐渐增大,进入-280m中段开采后,采准工程的塌冒已经严重影响生产的正常进行。经过调查巷道发生破坏的部位与破坏区岩性变化,查明上盘楔形体围岩的附加力作用是引发回采巷道大规模破坏的主要原因,为此提出卸压开采方案,即在高应力区先回采上分段沿脉进路,为下分段卸掉垂直压力后,再掘进下分段沿脉进路。此外,根据巷道破坏过程与地压显现形式,分析了现用工字钢金属架支护方法的不适应性,提出根据岩性与地应力大小选择树脂锚杆、喷锚网联合支护的改进方案。初步试验表明,改进方案可有效解决上盘沿脉巷道的塌冒难题,并可较好地适应弓长岭井下矿深部矿岩条件,不失为弓矿实用技术。Thierno Amadou Mouctar Sow 任凤玉 陈晓云 2012采矿技术2012,12,5:5
4Study of the impact of the compaction and curing temperature on the behavior of cold bituminous recycled materials显示文摘In most countries, there is a low temperature limit to lay down hot asphalt mixes because if it is too cold, it becomes impossible to get proper compaction. For cold recycled bituminous mixture(CRM), there is little information on the effect of the low temperature on their behavior. The goal of this study is to evaluate, in laboratory, the impact of the compaction and curing temperature on the behavior of CRM. To do so, CRM containing 50%reclaimed asphalt pavement(RAP) and 50% natural aggregates treated with foamed asphalt or bituminous emulsion were mixed and cured at different temperature between 0 and23℃ for up to 10 days before being tested in indirect tension. The results show that for all mixes, a cure at lower temperature means lower tensile strength, but the decrease is more noticeable for emulsion treated materials than for foamed treated mixes. The trend is not as obvious for Marshall stability results. A second cure at ambient temperature was also done, and the analysis of the results showed that the decrease in mechanical performance remains important even after a second cure at higher temperature for all mixes treated with bituminous emulsion, but there is some mechanical gain for mixes treated with foamed asphalt.Apparao Gandi Alberto Cardenas Djibril Sow Alan Carter Daniel Perraton 2019Journal of Traffic and Transportation Engineering(English Edition)2019,6,4:4
5Composition-dependent ultra-high photoconductivity in ternary CdSxSe1-x nanobelts as measured by optical pump-terahertz probe spectroscopy显示文摘我们采用光泵兆兆赫探查光谱学在第三的 CdS x Se1x nanobelts 调查作文依赖者光导增益。CdS nanobelts 的观察搬运人动力学第三的 CdS x Se1x nanobelts 比那些显示许多更短的一生。这作为潜在地以切换的速度交换设备直到 46.7 GHz 的 ultrafast 显示 CdS nanobelts 的实现。令人惊讶地,第三的 CdS x Se1x nanobelts 被发现比二进制 CdS 和 CdSe 展出高得多的光导增益。这在第三的混合物被归因于更高的 photocarrier 密度。另外,在样品的 Se 的存在导致了突出的象 CdSe 一样横向光(到) 声子模式由于电子声子相互作用。这个模式的力量在 photoexcitation 之上显示出大落下,但是与时间逐渐地恢复。这些结果证明第三的 nanostructures 的生长能被利用在 nanostructures 减轻高表面缺点密度并且改进他们的光导增益。Hongwei Liu Junpeng Lu Minrui Zheng Sing Hai Tang Xinhai Zhang Chorng Haur Sow 2013Nano Research2013,6,11:3
6两种养殖模式中草鱼土腥味特征性物质累积变化显示文摘为探究养殖模式对草鱼(Ctenopharyngodon idella)养殖水体和肌肉中土腥味物质含量的影响,研究了池塘内循环跑道养殖系统(In-pond raceway system,IPRS)与传统养殖模式对草鱼中土腥味特征性物质土臭素(Geosmin,GSM)和二甲基异莰醇(2-methylisoborneol,2-MIB)累积的影响。通过对不同养殖模式中水体和草鱼肌肉中2-MIB、GSM的动态检测,探究养殖过程中影响土腥味物质累积的因素。结果表明,IPRS水体和鱼肉的2-MIB随养殖时间的延长显著上升,GSM呈现相同的逐步累积趋势,且鱼肉中这2种特征性土腥味物质的变化趋势与水体一致。传统养殖模式下,水体中2-MIB含量逐渐增加,鱼肉中的2-MIB含量在实验末期显著高于实验初期和中期;水体中GSM的变化差异不显著,鱼肉与水体的GSM含量变化趋势一致,但不同时期鱼肉中的GSM含量差异显著(P<0.05),且实验末期达最大值。相关性分析表明,土腥味物质的累积量与草鱼体质量、体长呈正相关。综上,养殖水体和草鱼肌肉中土腥味物质的累积受养殖模式影响,规格为0.42~1.23 kg的草鱼的土腥味特征性物质累积速率更快。闫莉 李慷 KAMALA Gharti Chetri 鲁强 徐岩 刘如聪 王桂香 ABDOUL Gadiri Sow 刘利平 2022南方水产科学2022,18,3:2

18Polychromic carbon black: Laser galvanized multicolour fluorescence display显示文摘Recovered carbon black (rCB),a very economical and abundance source of material,is transformed into dazzling multicolour fluorescence and visual display for the first time by way of a scanning focused laser treatment.This laser-initiated process is both straightforward and versatile,catering to both micro-and macro-scopic patterning with the sample in ambient or helium environment.The observed phenomenon is attributed to both chemical and structural induced colouration of rCB powder.Chemically,carbon infusion of oxidised metal occurs when photothermal reaction takes place in ambient.After laser modification with the sample in helium environment,the powder not only fluoresces due to sulphur impurities,control annealing of these powders results in formation of periodic arrangements of carbon nanoparticles.The periodicity of these arrangement falls within the range of visible wavelength,hence contributing to the visually observable rainbow coloured rCB flakes.The patterned sample is also transferrable using PDMS stamps.This in turn broadens the application of this material in flexible electronic devices/displays.Photocurrent measurements show most significant enhancement under yellow light illumination.Furthermore,in the presence of an applied potential,the fluorescence detected from the sample can easily be switched off.All in all,we present a simple process to add multiple functionalities to a material that is both inexpensive and sustainable.Sharon Xiaodai Lim Kae Lin Wong Zheng Zhang Antonio H.
