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
3Emotion processing in Parkinson's disease: a blood oxygenation level-dependent functional magnetic resonance imaging study显示文摘Parkinson's disease is a neurodegenerative disorder caused by loss of dopamine neurons in the substantia nigra pars compacta. Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade. The aim of this study was to investigate emotional processing organization in the brain of patients with Parkinson's disease and to explore whether there are differences between recognition of different types of emotions in Parkinson's disease. We examined 18 patients with Parkinson's disease(8 men, 10 women) with no history of neurological or psychiatric comorbidities. All these patients underwent identical brain blood oxygenation level-dependent functional magnetic resonance imaging for emotion evaluation. Blood oxygenation level-dependent functional magnetic resonance imaging results revealed that the occipito-temporal cortices, insula, orbitofrontal cortex, basal ganglia, and parietal cortex which are involved in emotion processing, were activated during the functional control. Additionally, positive emotions activate larger volumes of the same anatomical entities than neutral and negative emotions. Results also revealed that Parkinson's disease associated with emotional disorders are increasingly recognized as disabling as classic motor symptoms. These findings help clinical physicians to recognize the emotional dysfunction of patients with Parkinson's disease.Mohammed Benzagmout Sa?d Boujraf Badreeddine Alami Hassane Ali Amadou Halima El Hamdaoui Amine Bennani Mounir Jaafari Ismail Rammouz Mustapha Maaroufi Rabia Magoul Driss Boussaoud 2019Neural Regeneration Research2019,14,4:6
4哈尔滨城市森林土壤对污水的净化能力显示文摘为探明城市森林不同林型土壤对污水净化能力,为水岸防护林的配置提供依据,选择哈尔滨市城市林业示范基地内代表性的3种人工林(蒙古栎、黄檗、水曲柳)为研究对象,将无植被生长的裸地作为对照,通过室内土柱模拟法,定期采集马家沟污水进行室内模拟浇灌,对土柱中淋滤液进行成分测定。结果表明:所选的3个林型对铵态氮的去除效果显著(P<0.05),各林型土柱吸附的铵态氮量以及各林型与对照之间差异均不显著(P>0.05);3个林型及对照土柱淋滤液中硝态氮量与未经土柱过滤的污水相比均极显著增加(P<0.01),且滤出的硝态氮量随着进水量的增加而增加,3个林型土柱淋出的硝态氮量均低于对照,但差异并不显著(P>0.05),各林型间的差异也不显著;3个林型及对照土柱淋滤液的p H值均显著低于未经土柱过滤的污水;各林型土柱淋滤液中溶解氧均高于未经土柱过滤的污水,但差异并不显著,且与对照无显著差异;除蒙古栎人工林外,其他两个林型及对照土柱淋滤液的氧化还原电位、电导率和总溶解固体与未经土柱过滤的污水相比均显著增加。段文标 段文靖 陈立新 沈海龙 韩冬荟 曲美学 Amadou Touré 张玉双 2018生态学杂志2018,37,7:6
5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

7Geographic information technology usage in developing countries – A case study in Mozambique显示文摘Geographic information technologies(GIT)have matured,have become pervasive throughout many types of organizations over recent decades and gained a wide range of attention in diverse sectors of society.The goal of this paper is to identify the main drivers and uses of GIT in organizations and to give an overview of GIT uses in developing countries with a focus on a case study developed for Mozambique by analyzing the results of a survey of 123 Mozambican organizations that are current GIT users.The results show that the main drivers behind are compatibility,complexity,competitive pressure,donor pressure,government policy,intention to adopt,innovation,relative advantage,security,and technology competence.Organizations of the public and private sectors use GIT for customer/resource/risk management,decision support,education,research,monitoring,prediction,simulation,suitability analysis,sustainability,use and access.Nelson Amade Marco Painho Tiago Oliveira 2018Geo-Spatial Information Science2018,21,4:2
