Abstract: In order to realize the high-yield, high-efficiency and safe production of high-gas outburst mines, the gas drainage technology application in the goaf of a coal mine was carried out. A test investigation to improve the gas drainage concentration in the goaf, a gas change parameter investigation on the simulated failure pump stop working face, a gas overrun and production situation inspection, and a gas extraction test to close the goaf when the tail exhaust effect is poor were carried out. The effects of gas drainage in goaf were summarized. The study results not only solved the problem of gas overrun at the return corner of the working face and gas overrun of coal production, but also provided a reference for the gas control of high-efficiency and efficient construction of similar mines.

Abstract: Agricultural economy is not only related to the national economy and people's livelihood, but also the necessary channel for hundreds of millions of farmers to survive. In recent years, with the enhancement of people's awareness of environmental protection and the deepening of the understanding of the concept of green consumption, Chinese people's demand for high-quality and green agricultural products is growing. At the same time, the export of agricultural products in China is increasingly restricted by green barriers, and the implementation of green logistics of agricultural products has become an inevitable choice for the development of agricultural economy in China. This paper analyzes the problems and further development of green logistics of agricultural products in China, and discusses the mechanism of coordinated development of green logistics of agricultural products and agricultural economy in China.
Keywords: Green logistics, Agricultural economy, Development mechanism

Abstract: In order to achieve the purpose of coal mine long bedding drilling high-efficiency, the main factors affecting the hole-forming effect of the bedding drilling were analyzed, the technical ways to increase the hole-forming length of the soft outburst coal seam were studied, and a reasonable drilling construction parameters, wind slag discharge parameters and suitable auger rigs have proposed a new set of long bedding drilling gas drainage technology, and carried out on-site practice at the Wangpo coal mine 3212 working face. The results show that the drilling technology using spiral drilling and air pressure slag discharge, large-capacity spiral drilling rigs and supporting drilling tools are currently the main technical ways to increase the length of holes formed in soft and outburst coal seams. After using the new complete bedding gas drilling technology in the 3212 working face, the hole-forming rate can be increased from 7.5% to 14.3%, the average hole depth increased by 12.3%, and the average daily drilling footage increased by 26%. It shows that under the condition of extremely difficult coal seam drilling, the new set of gas drainage technology and equipment has stronger adaptability and better hole-forming effect.

Synthetic Evaluation of Power Quality Based on Prospect Theory and Membership Grade
Author: Liguo Fan
Author affiliation: Department of Economic Management, North China Electric Power University, Baoding , China
Abstract: In view of the problem of synthetic evaluation of power quality, considering that measured data of observation points vary during monitoring period, their values may be clear numbers, interval numbers and linguistic assessment terms. At the same time, considering that the decision makers have certain expectations for the power quality index, a hybrid multi-attribute synthetic evaluation method of power quality based on prospect theory and membership grade is proposed. Firstly, Decision matrix with clear numbers, interval numbers and linguistic assessment terms is transformed into a prospect decision matrix according to the expectation of each attribute. Then, variable fuzzy pattern recognition model is established according to the generalized weighted Euclidean distance between each alternative and decision expectation. Thirdly, optimal membership grade and corresponding attribute weight of each alternative are obtained by means of building a Lagrange relaxation function to carry out the cross iterative calculation. Finally, by synthesizing accumulative prospect value and membership grade, ranking results of each alternative is determined according to comprehensive prospect value. Synthetic evaluation of power quality is realized.

Abstract: Powder metallurgy connecting rod is the main moving part of refrigerator compressor. During the surface treatment, it is easy to form crystal like viscous yellow foreign matters on its surface, which causes the connecting rod and the matched parts to be stuck, and the compressor does not start. In this paper, firstly, the influence of steam treatment on the processing of connecting rod and the production of yellow foreign matters is compared and analyzed, then the processing and surface treatment process before the use of connecting rod are discussed and compared, and the process of eliminating the production of yellow foreign matters from the source is studied. Finally, the feasibility of adopting the new process is confirmed through the comparative test and test method analysis.

Study on the direct impact of environmental regulation policy on carbon emission intensity in China
Author: Xinli Wang
Author affiliation: School of Economics and Management, North China Electric Power University, China.
Abstract: The assessment of the effectiveness of differentiated environmental regulation policies on China's carbon emissions is an important research topic to accelerate the transformation of China's low-carbon economy. This paper uses the systematic GMM method to investigate the heterogeneous effects of three environmental regulation policies. The results show that: (1) the direct impact of emission fee on carbon emission intensity is inverted U-shaped, but the impact is not significant. (2) The investment in industrial pollution control directly suppresses carbon emission without "green paradox".;(3) The direct impact of local environmental protection standards on carbon emissions has produced a "green paradox" effect. The above results show that China's current environmental regulation policies can effectively curb carbon emissions. Identifying the differences in the effectiveness and impact paths of different environmental regulation policies can provide reference for government departments to formulate, and maximize the carbon emission reduction effect of different environmental regulation policies, and promote China's implementation Now we are committed to carbon emission reduction in the world.
Keywords: Environmental regulation, Green paradox, Backward emission reduction
