Research on software development of air temperature prediction in coal face

Journal of Coal Science & Engineering(China) 2011年第3期17卷 294-297页

作者： QIN Yue-ping LIU Hong-bo WANG Ke LIU Jiang-yue State Key Laboratory of Coal resources and Safe Mining China University of Mining and Technology （Beijing） Beijing 100083 China

With ever-increasing depth of coal mine and the continuous improvement of mechanization, heat damage has become one of the major disasters in coal mine exploitation. Established the temperature prediction models suitable for different kinds of tunnels through analysis of the heat of shafts, roadways and working faces. The average annual air temperature prediction equation from the inlets of shafts to the working faces was derived. The formula was deduced using combine method of iteration and direct calculation. The method can improve the precision of air temperature prediction, so we could establish the whole pathway air temperature prediction model with high precision. Emphasizing on the effects of leakage air to air temperature of working face and using the ideology of the finite difference method and considering the differential equation of inlet and outlet at different stages, this method can significantly improve the accuracy of temperature prediction. Program development uses Visual Basic 6.0 Language, and the Origin software was used to fit the relevant data. The predicted results shows that the air temperature generally tends to rapidly increase in the air inlet, then changes slowly on working face, and finally increases sharply in air outlet in the condition of goaf air leakage. The condition is in general consistent with the air temperature change tendency of working face with U-type ventilation system. The software can provide reliable scientific basis for reasonable ventilation, cooling measures and management of coal mine thermal hazards.

A comparative study on institutional collaboration characteristics in EM and LIS in China

引用

Chinese Journal of Library and Information Science 2015年第4期 62-77页

作者： Yating LI Bin ZHANG Center for Studies of Information resources Wuhan University

Purpose： This study analyzes the current status of institutional cooperation in economics and management （EM） and library and information science （LIS） in China.Design/methodology/approach： Based on the Chinese Social Science Citation Index （CSSCI） database, we constructed institutional collaboration networks in EM and LIS, and analyzed the collaboration characteristics through social network analysis.Findings： In the development and evolution of the collaboration network of institutions in humanities and social sciences, EM is always at the center. It has extensive cooperation relationships with other fields. The position of LIS has also become centralized, and its interdisciplinary cooperation has increased. For both EM and LIS, we observed ＂small-world＂ and ＂scale-free＂ networks, indicating full communication and mature development in both disciplines. Based on a comparison of two institutions in the two fields, we confirmed the comprehensive development in EM and the extensive information exchange in LIS.Research limitations： We collected data only from humanities and social sciences, but did not consider the connection between EM and natural sciences, or between LIS and natural sciences. In addition, the paper lacks analysis of institutional collaboration at the micro level.Practical implications： The paper provides insights into the institutional cooperation characteristics in EM and LIS in China.Originality/value： The paper offers a new perspective on the characteristics of institutional collaboration in China.
