| 1 | Width design for gobs and isolated coal pillars based on overall burst-instability prevention in coal mines显示文摘An investigation was conducted on the overall burst-instability of isolated coal pillars by means of the possibility index diagnosis method(PIDM). First, the abutment pressure calculation model of the gob in side direction was established to derive the abutment pressure distribution curve of the isolated coal pillar. Second, the overall burst-instability ratio of the isolated coal pillars was defined. Finally, the PIDM was utilized to judge the possibility of overall burst-instability and recoverability of isolated coal pillars.The results show that an overall burst-instability may occur due to a large gob width or a small pillar width. If the width of the isolated coal pillar is not large enough, the shallow coal seam will be damaged at first, and then the high abutment pressure will be transferred to the deep coal seam, which may cause an overall burst-instability accident. This approach can be adopted to design widths of gobs and isolated coal pillars and to evaluate whether an existing isolated coal pillar is recoverable in skip-mining mines. | Junfei Zhang Fuxing Jiang Sitao Zhu Lei Zhang | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，4： | 6 |
| 2 | Evolution and modeling of mine water inflow and hazard characteristics in southern coalfields of China:A case of Meitanba mine显示文摘In this paper,the hydrogeological characteristics in the southern coalfields of China are first briefly outlined.Then,taking the Meitanba mine as an example,the evolution and modeling of mine water inflow are studied.Finally,the hazard characteristics related to mine water and mud inrush are analyzed.The results show that the main mine water sources in the Meitanba mine area are groundwater,surface water and precipitation.The evolution of mine water inflow with time indicates that the water inflow is closely related to the development of karst structures,the amount of water from rainfall infiltration,and the scope of groundwater depression cone.The mine water inflow increases with time due to the increase in mining depth and the expansion of groundwater depression cone.Using the big well method and following the potential superposition principle,a hydrogeological model considering multi-well interactions has been developed to predict the mine water inflow.Based on the monitored data in the Meitanba mine area over a period of nearly 60 years,it is found that with increasing mining depth,the number of water and mud inrush points tended to decrease.However,the average water and mud flow rate per point tended to increase. | Jinhai Liu Yanlin Zhao Tao Tan Lianyang Zhang Sitao Zhu Fangyan Xu | 2022 | International Journal of Mining Science and Technology2022，32，3： | 2 |
| 3 | Electrical and Optical Properties of Nano Aluminum Film/Particle Structure显示文摘The electrical and optical effects of particles on the nano aluminum film deposited by thermal evaporation was investigated. From the characterization results of scanning electron microscope(SEM), the accumulation in tens of nanometers had been observed. The current-voltage(I-V) curve of the sample indicates its nonlinear electrical characters expecting the corresponding nonlinear optical properties. By the theoretical calculation, nonlinear conduction of the carrier transportation may result from the barrier-well-barrier structure, where negative resistance and Coulomb blockade effect appears. The simulation results are approximately matched with the experimental results. By testing the fluorescence emission spectrum of the sample, peaks were found to be located at 420 and 440 nm. In addition, the full width at half maximum(FWHM) had been obviously broadened by means of adding 2, 5-diphenyloxazole(DPO). Therefore, discrete energy levels could be estimated inside those particles. | 孟庆云 LI Siqi KANG Yixin ZHAI Xiaoyu WEI Sitao HE Huimei 王云 殷子文 | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，5： | 2 |

| 16 | Effect of Rho-kinase pathway on neurite outgrowth of rat hippocampal neurons under atomic force microscopy显示文摘Hippocampal neurons of neonatal rats were cultured in serum-free culture medium for 5 days in vitro, and treated with the Rho-kinase inducer lysophosphatidic acid. Atomic force microscopy revealed that the numbers of level-1, -2 and -3 neurites protruding from rat hippocampal neurons was significantly reduced. After treatment with the Rho kinase inhibitor Y27632, a significant increase in the numbers of these neurites was observed. Our experimental findings indicate that the Rho-kinase pathway is closely associated with the neurites of hippocampal neurons. | Jing Chen Hu Hao Guoqing Guo Sitao Li Xin Xiao | 2012 | Neural Regeneration Research2012，7，7： | 1 |
| 17 | Permafrost environment monitoring on the Qinghai-Tibet Plateau using time series ASAR images显示文摘The permafrost in Qinghai-Tibet Plateau(QTP)has long been the focus of many researchers.In this study,we first use the method that integrates synthetic aperture radar(SAR)intensity and phase information to monitor permafrost environment in the Beiluhe Region,using time series advanced SAR images.The backscattering coefficients(σ^(0))and deformation were extracted for the main features,and the influences of meteorological conditions to them were also quantified.The results show that both the change inσ^(0)and surface deformation are closely related to the active layer,and the deformation is also affected by the permafrost table.First,over meadow and sparse vegetation regions,σ^(0)rose about 6.9 and 4 dB from the freezing to thawing period,respectively,which can be mainly attributed to the thaw of the active layer and increased precipitation.Second,seasonal deformation,derived from the freeze-thaw cycle of the active layer,was characteristic of frost heave and thaw settlement and exhibited a negative correlation with air temperature.Its magnitude was larger than 1 cm in a seasonal cycle.Last,significant secular settlement was observed,with rates ranging from-16 to 2 mm/a,and it was primarily due to the thaw of the permafrost table caused by climate warming. | Zhen Li Panpan Tang Jianmin Zhou Bangsen Tian Quan Chen Sitao Fu | 2015 | International Journal of Digital Earth2015，8，10： | 1 |
