Reconstructing Human‒Coal Space Relationship Through Coalmine Intellectualization

Fan Jingdao, Jin Zhixin, Wang Guofa, Li Chuan, Liu Wei, Yan Zhenguo

Strategic Study of CAE 2023, Volume 25, Issue 2, Pages 243-253 doi: 10.15302/J-SSCAE-2023.07.014

Abstract:

The human‒coal space relationship is significant for the safe and efficient production of coalmines. Reconstructing the human‒coal space order using intelligent technologies in coalmines will provide a core technical support for the high-quality development of the coal industry. This study examines the evolution and research progress of the human‒coal space relationship and proposes a human‒physical‒information (HPC) space form to break constraints from the traditional human‒physical space structure of coalmines. We find that coalmine intellectualization can change the physical locations and relative motions of coalmine production factors; it can reconstruct the three major factors of production, establish an integrated intelligent production management mode, and improve the development space of miners’ social values, thereby achieving an interconnection-of-everything production scene and liberating human from underground mining. Moreover, the study analyzes intelligent coal-mining and intelligent well-construction cases and reveals the practical values of coal mine intellectualization for the change of the human‒coal space relationship. We suggest that a development mode integrating new-generation technologies and modern coalmines should be established based on the intelligent HPC space theory of coalmines and by targeting human liberation and comprehensive development. This will promote the safe, efficient, intelligent, and green development and thus the overall upgrading of the coal industry.

Collaborative learning via social computing None

Ricardo S. ALONSO, Javier PRIETO, Óscar GARCÍA, Juan M. CORCHADO

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 2, Pages 265-282 doi: 10.1631/FITEE.1700840

Abstract:

Educational innovation is a field that has been greatly enriched by using technology in its processes, resulting in a learning model where information comes from numerous sources and collaboration takes place among multiple students. One attractive challenge within educational innovation is the design of collaborative learning activities from the social computing point of view, where collaboration is not limited to student-to-student relationships, but includes student-to-machine interactions. At the same time, there is a great lack of tools that give support to the whole learning process and are not restricted to specific aspects of the educational task. In this paper, we present and evaluate context-aware framework for collaborative learning applications (CAFCLA) as a solution to these problems. CAFCLA is a flexible framework that covers the entire process of developing collaborative learning activities, taking advantage of contextual information and social interactions. Its application in the experimental case study of a collaborative WebQuest within a museum has shown that, among other benefits, the use of social computing improves the learning process, fosters collaboration, enhances relationships, and increases engagement.
