Yu Jiang, Yuning Yang, Rui Li, Beidou Xi, Mingxiao Li, Yan Hao, Fanhua Meng, Shaobo Gao, Lei Chen

Strategic Study of CAE 2018, Volume 20, Issue 5,   Pages 142-147 doi: 10.15302/J-SSCAE-2018.05.021

Abstract:

The coordinated development of Beijing, Tianjin, and Hebei is the core strategy of China’s political, economic, scientific, and cultural construction. The environmental protection of regional agricultural producing areas is a strategic location for the battle against pollution. The problem of excessive heavy metals Cd and Hg in the soil of agricultural producing areas is prominent in Beijing and Tianjin, and the pollution risk cannot be ignored. The main causes of soil pollution in the agricultural producing areas in the Beijing–Tianjin–Hebei region are heavy metal pollution by industrial development zones, sewage irrigation, inadequate sewage treatment capacity, imperfect regulations and policies, and backward technical standards. This study proposed to comprehensively deploy a “sky-ground integrated” environment monitoring system for the agricultural producing area, implement the clean production of in-dustrial and mining enterprises, and promote comprehensive strategies of soil pollution prevention and control such as comprehensive management of livestock and poultry pollution. Engineering cases for environmental pollution prevention and control of a pit-pond pollution site and an informal refuse landfill in Tianjin are enumerated to provide references for strategic decisions of soil pollution prevention and control in the Beijing–Tianjin–Hebei agricultural producing areas.

Environmental Protection System Engineering and Case Studies of Agricultural Products Producing Areas in Southern China——Taking Poyang Lake as an Example

Caihong Huang, Beidou Xi, Wenchao Yuan, Zhurui Tang

Strategic Study of CAE 2018, Volume 20, Issue 5,   Pages 148-152 doi: 10.15302/J-SSCAE-2018.05.022

Abstract:

As an important part of the Middle-Lower Yangtze Plain, the Poyang Lake Plain is an important commodity grain production base in China, with a good environmental quality, a low level of heavy metal pollution in soil, and a low ratio of pollution sites. Therefore, environmental protection system engineering in Poyang Lake agrees with the environmental protection concept of giving priority to protection, and could be a typical and representative case for the agricultural producing areas in Southern China. This paper clarifies the main environmental problems of the Poyang Lake Plain and analyzes the causes. It proposes environmental quality improvement measures and key projects based on a landscape-forest-lake systemic protection concept, which has important guiding significance for the improvement of environmental quality of the main agricultural producing areas in the Poyang Lake area. The results show that environmental pollution in the Poyang Lake Plain is dominated by heavy metal pollution in soil, the proportion of living-source pollution is increased, livestock and poultry breeding pollution has not yet been effectively curbed, and industrial and mining enterprises as well as the background value of heavy metals in soil are the main causes of pollution. Accordingly, measures should be implemented in the following three aspects. First, multiple environmental factors should be combined to strengthen systematic protection and unified supervision. Second, meticulous management should be performed by focusing on the water environment quality. Third, we should attach importance to environmental emergency plans and strictly control the pollution sources that may enter into the soil.

An Innovative Non-Pillar Coal-Mining Technology with Automatically Formed Entry: A Case Study Article

Xingyu Zhang, Manchao He, Jun Yang, Eryu Wang, Jiabin Zhang, Yue Sun

Engineering 2020, Volume 6, Issue 11,   Pages 1315-1329 doi: 10.1016/j.eng.2020.01.014

Abstract:

A non-pillar coal-mining technology with an automatically formed entry is proposed, which reduces the waste of coal resources and the underground entry drivage workload. Three key techniques in this technology cooperate to achieve automatic formation and retaining of the gob-side entry, and to realize non-pillar mining. Constant-resistance large deformation (CRLD) support ensures the stability of the entry roof; directional presplitting blasting (DPB) separates the entry roof and the gob roof; and a blocking-gangue support system (BGSS) integrates the caved rock material as an effective entry rib. An industrial test was conducted to verify the engineering effects of these key techniques. The field application results showed that the retained entry was under the pressure-relief zone due to the broken-expansion nature of the caved rock mass within the DPB height. After going through a provisional dynamic pressure-bearing zone, the retained entry entered the stability zone. The final stable entry meets the requirements of safety and production. The research results demonstrate the good engineering applicability of this technology. By taking the framework of the technology design principles into consideration and adjusting the measures according to different site conditions, it is expected that the proposed non-pillar coal-mining technology can be popularized on a large scale.

Abstract:

The "Numerical Control (NC) Generation Innovation Project" aims to apply NC technology to the mechanical products of all industries to update and upgrade the overall installed base of manufacturing equipment, thus promoting upgrading of the industrial base. This paper takes the update and upgrade of NC equipment in Quanzhou city as a case study. Focusing on practical experience with the NC Generation Innovation Project within the framework of innovation governance, it discusses a new generation of "organized innovation" generated by the collaboration of multiple innovation participants. Through analysis and on the basis of strong demand pull from the user market and effective technology push from R&D agencies, the NC Generation Innovation Project, by playing a "skillful deflection" role, has enabled the government to kick-start extensive market resource investment with a small amount of policy resources, to mobilize the enthusiasm of multiple innovation participants such as enterprises, R&D institutions, intermediaries, and financial institutions and to organize many manufacturing enterprises in different industries. Using the principles of the market economy, these enterprises overcame all kinds of obstacles, actively accepting key generic technology. The result is a successful example of promoting generic technology diffusion in manufacturing industries. At the same time, this project has found existing insufficiencies in the course of summarizing the existing successful experience and has provided a decision-making basis for advancing of a broad-based manufacturing industry upgrade.

Adverse Geology Identification Through Mineral Anomaly Analysis During Tunneling: Methodology and Case Study Article

Zhenhao Xu, Tengfei Yu, Peng Lin, Shucai Li

Engineering 2023, Volume 27, Issue 8,   Pages 150-160 doi: 10.1016/j.eng.2022.09.013

Abstract:

Accurate and effective identification of adverse geology is crucial for safe and efficient tunnel construction. Current methods of identifying adverse geology depend on the experience of geologists and are prone to misjudgment and omissions. Here, we propose a method for adverse geology identification in tunnels based on mineral anomaly analysis. The method is based on the theory of geoanomaly, and the mineral anomalies are geological markers of the presence of adverse geology. The method uses exploration data analysis (EDA) to calculate mineral anomaly thresholds, then evaluates the mineral anomalies based on the thresholds and identifies adverse geology based on the characteristics of the mineral anomalies. We have established a dynamic expansion process for background samples to achieve the dynamic evaluation of mineral anomalies by adjusting anomaly thresholds. This method has been validated and applied in a tunnel excavated in granite. As shown herein, in the tunnel range of 142 + 80 0–142 + 860, the fault F37 was successfully identified based on an anomalous decrease in the diagenetic minerals plagioclase and hornblende, as well as an anomalous increase in the content of the alteration minerals chlorite, laumonite, and epidote. The proposed method provides a timely warning when a tunnel enters areas affected by adverse geology and identifies whether the tunnel is gradually approaching or moving away from the fault. In addition, the applicability, accuracy, and further improvement of the method are discussed. This method improves our ability to identify adverse geology, from qualitative to quantitative, and can provide reference and guidance for the identification of adverse geology in mining and underground engineering.

Multiple knowledge representation for big data artificial intelligence: framework, applications, and case studies Perspective

Yi Yang, Yueting Zhuang, Yunhe Pan,yangyics@zju.edu.cn,yzhuang@zju.edu.cn,panyh@zju.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 12,   Pages 1551-1684 doi: 10.1631/FITEE.2100463

Abstract: In this paper, we present a multiple knowledge representation (MKR) framework and discuss its potential for developing big data artificial intelligence (AI) techniques with possible broader impacts across different AI areas. Typically, canonical knowledge representations and modern representations each emphasize a particular aspect of transforming inputs into symbolic encoding or vectors. For example, knowledge graphs focus on depicting semantic connections among concepts, whereas deep neural networks (DNNs) are more of a tool to perceive raw signal inputs. MKR is an advanced AI representation framework for more complete intelligent functions, such as raw signal perception, feature extraction and vectorization, knowledge symbolization, and logical reasoning. MKR has two benefits: (1) it makes the current AI techniques (dominated by deep learning) more explainable and generalizable, and (2) it expands current AI techniques by integrating MKR to facilitate the mutual benefits of the complementary capacity of each representation, e.g., raw signal perception and symbolic encoding. We expect that MKR research and its applications will drive the evolution of AI 2.0 and beyond.
