Raw Gangue Filling Mining under Construction —A Case Study in China

In order to recover the strip pillar coal resources, reduce the amount of gangue mountain and realize remediation of the goaf environment in the old mining area, the raw gangue filling mining technology was proposed. According to the previous practical experience, the feasibility of the implementation of raw gangue filling mining technology in the coal-pressed area was analyzed. Through the filling gangue compaction test, the deformation under different loading stages was obtained. Further, a reasonable prediction of the deformation beyond the experimental limited loading load was made based on the experimental results. Through the deformation source analysis of the whole process of gangue filling, the key factors for controlling deformation before, during, and after filling were determined. Additionally, the proportion of deformation during different stages was quantified. Considering the protection of surface buildings, mining fullness of the working face and mining technology, the production parameters of 1209 and 1210 filling working faces were preliminarily determined. Through numerical simulation, the rationality of mining scheme was verified. Based on the practice of 1209 working face and the key factors to control the deformation of gangue filling, the mining system and process in 1210 working face were optimized. According to the measured surface rock movement, raw gangue filling mining technology can meet the requirements of surface building protection level. Especially, this paper provides a method to quantitatively calculate the equivalent mining height (EMH) of raw gangue filling and its mining deformation, which has reference significance for old mining areas.

Build an International Teaching Resource Construction System and Practice International Talent Training in the Context of “Double First-class” ——Take the School of Software of Northwestern Polytechnical University Case as an Example

From the perspective of the development of world-class universities,internationalization is an essential strategic choice and external feature,and also an inevitable choice to improve the discourse power and competitiveness of international higher education.In line with the national“double first-class”international development strategy of higher education,based on the cultivation of students’overall quality,the improvement of teachers’professional ability,and the development of school’s improvement of quality and efficiency,we School of Software,Northwestern Polytechnical University,explore new ideas and new measures for the cultivation of international software engineering talents,build a set of international teaching resources construction system,to form a reference standard and scheme for the cultivation of international software engineering talents.At present,we have achieved excellent results.

上海市精神卫生专科医院心理应急管理现状研究

目的 了解新型冠状病毒肺炎疫情影响下上海市精神卫生专科医院心理应急管理现状及面临的主要问题,为建立健全精神卫生专科医院心理应急管理体系提供对策和建议。方法 采用定量研究和定性研究相结合的方法,面向上海市18家精神卫生中心的心理危机干预管理人员及272名心理危机干预队伍成员开展问卷调查,选取24名心理危机干预相关工作人员进行访谈。结果 (1)管理设置方面,18家医院中仅上海市精神卫生中心设置了独立的心理危机干预办公室,15家(83.3%)已制定心理应急总体干预方案或预案,11家(61.1%)已建立健全心理应急管理相关制度,12家(66.7%)配备心理危机干预工作经费。(2)队伍建设方面,心理危机干预队员以兼职为主(84.9%),年龄主要在35~<45岁(47.8%),96.3%的队员具有大学本科及以上学历,所学专业以精神医学为主(40.4%),85.7%的队员具有心理咨询师资格证书,40.1%的队员具有突发公共卫生事件心理危机干预经验,81.3%的队员能够有效处理创伤后心理问题。(3)心理应急管理过程中存在的主要问题包括队员压力过大、能力水平参差不齐、队伍人手不足和保障机制不完善4个方面。结论 目前,上海市已初步形成心理危机干预体系,但在管理机制和队伍建设方面仍存在不足。建议进一步完善心理危机干预体系管理机制和人才队伍建设。

General review of National Digital Library development in the National Library of China

As an important part of National Digital Library(NDL),the National Digital Library Project(NDLP),which was launched in 2005,has attracted wide attention of the society in general.This paper introduces the general situation of the project from the following aspects,namely,the characteristics,objectives and contents.It also expounds on the basic ideas and the overall structure of the project and gives an introduction to the design of its basic platform,its application platform,its business management system and its standardization control system.In this paper,the digital resources construction and service delivery of the National Library of China(NLC)are introduced to cover both its present operation as well as those in conjunction with the opening of its new library building during its second-phase of library development.Finally,the most important and difficult point in the construction of the National Digital Library Project is analyzed from the following four perspectives:1)The long-term preservation of digital resources;2)the construction of knowledge organization system;3)the organic integration of the digital library and the traditional library;and 4)the risk of project management and system integration.
