| 1 | Mechanism of rock burst caused by fracture of key strata during irregular working face mining and its prevention methods显示文摘To study the occurrence mechanism of rock burst during mining the irregular working face,the study took irregular panel 7447 near fault tectonic as an engineering background.The spatial fracture characteristic of overlying strata was analyzed by Winkler elastic foundation beam theory.Furthermore,the influence law of panel width to suspended width and limit breaking span of key strata were also analyzed by thin plate theory.Through micro-seismic monitoring,theoretical analysis,numerical simulation and working resistance of support of field measurement,this study investigated the fracture characteristic of overlying strata and mechanism of rock burst in irregular working face.The results show that the fracture characteristic of overlying strata shows a spatial trapezoid structure,with the main roof being as an undersurface.The fracture form changes from vertical‘‘O-X'type to transverse‘‘O-X'type with the increase of trapezoidal height.From the narrow mining face to the wide mining face,the suspended width of key strata is greater than its limit breaking width,and a strong dynamic load is produced by the fracture of key strata.The numerical simulation and micro-seismic monitoring results show that the initial fracture position of key strata is close to tailgate 7447.Also there is a high static load caused by fault tectonic.The dynamic and static combined load induce rock burst.Accordingly,a cooperative control technology was proposed,which can weaken dynamic load by hard roof directional hydraulic fracture and enhance surrounding rock by supporting system. | Zengqiang Yang Chang Liu Hengzhong Zhu Fuxing Xie Linming Dou Jianhang Chen | 2019 | International Journal of Mining Science and Technology2019，29，6： | 12 |

| 4 | Analysis of the Correlation between Tourism and Climate in the Ancient City of Langzhong显示文摘Based on the meteorological data of Langzhong from 1981 to 2016,a comprehensive comfort index model of tourism climate suitable for Langzhong is established by calculating the meteorological and climatic factors affecting tourism in the ancient city of Langzhong.The model is used to evaluate the climate comprehensive comfort of Langzhong,and its grades and suitable tourism periods are divided.Based on the monthly index of passenger flow volume in the ancient city of Langzhong from 2013 to 2015,a mathematical model is established through OLS regression analysis to analyze the correlation between changes in monthly passenger flow volume in a year and the comprehensive comfort of tourism climate in the ancient city of Langzhong.The results show that the climate in Langzhong is suitable for tourism in spring and autumn.It is suitable for tourism from February to June and from September to December,of which it is most suitable for tourism from April to May and from September to October.It is less suitable for tourism in only January and from July to August,and there is no unsuitable period.The changes in monthly passenger flow volume in a year are mainly affected by the meteorology and climate.The changes of climate comprehensive comfort in various month have an extremely significant impact on passenger flow volume.The elastic coefficient of impact of climate comprehensive comfort index on the monthly index of passenger flow volume is 0.9614%. | Rui MA Linming XIE Shuhan JIA | 2020 | Meteorological and Environmental Research2020，11，4： | 0 |
| 5 | Design and Implementation of Multi-element Integration Platform Based on Tianqing Data显示文摘In order to better carry out meteorological service and improve service efficiency,based on Tianqing data multi-factor integration platform,using Tianqing intensive data source of big data cloud platform,daily and hourly precipitation,temperature and wind data can be acquired,and C#language can be used to realize data analysis,text template nesting,meteorological material generation and archive management functions.The application shows that the platform can quickly complete the production of rain information within 2 min,and the material filing management has zero errors,which is superior to the traditional methods in terms of framework design and data processing material management. | Peiqiang WANG Jing QING Linming XIE Qiqin ZHONG Shuhan JIA Rui MA Xiaobing YANG | 2022 | Meteorological and Environmental Research2022，13，2： | 0 |
