Deep Seismic Reflection Profiling Technology In Land Areas: A Review And Prospects, Yue Hangyu, Wang Xiaojiang, Wang Lei, Wang Kai, Zhang Baowei
Coal Geology & Exploration
Deep seismic reflection profiling has been internationally proven to be a leading technology for deep earth exploration. With longer arrangement and greater energy than those used in oil seismic exploration, this technology can detect the fine-scaled structures and tectonic features from the earth surface to the upper mantle. Therefore, it is widely applied to the detection of continental and marine crust and upper mantle, with fruitful achievements having been made in revealing deep earth dynamic processes, expounding on the geotectonic evolution, determining the basin-mountain coupling, inferring the metallogenic and reservoir formation conditions, and analyzing earthquake disasters. This paper systematically reviews …

Research And Practice On Key Technologies For Intelligentization Of Coal Mine, Wang Haijun, Cao Yun, Wang Honglei
Coal Geology & Exploration
Intelligentization of coal mine is an important way for coal industry to achieve sustainable development. It provides effective guarantee for coal mine enterprises to reduce workers, increase efficiency and improve the production safety. The new generation of information technologies, such as big data, robotics and artificial intelligence, strongly support the intelligent construction of coal mines. Firstly, the design ideas of intelligent mines are introduced in this paper, and the overall technical system of intelligent construction are developed. Secondly, the development status and trend of key technologies for the intelligentization of coal mine are analyzed, including the general heterogeneous control and …
Parallel Method For Extracting Pulses From Multi-Source Massive Partial Discharge Signals, Liuwang Wang, Yongli Zhu, Yafei Jia
Parallel Method For Extracting Pulses From Multi-Source Massive Partial Discharge Signals, Liuwang Wang, Yongli Zhu, Yafei Jia
Journal of System Simulation
Abstract: Aiming at the issue of discharge pulse extraction for multi-source and massive PD signals, a novel parallel method based on Message Passing Interface was proposed. The proposed method applied a parallel mode called manager-worker-writer. In this method, a manager dynamically assigned task to several workers, and these workers executed tasks in parallel and a writer received results from workers in real time, so data management was separated from task execution. In addition, the manager identified sources of PD signals and sent them to workers as the keys for analyzing different data files and setting algorithm parameters, so multi-source and …
