Study on Key Parameters of Directional Long Borehole Layout in High-Gas Working Face by Zhenguo Yan, Yanping Wang, Jingdao Fan, Yuxin Huang, Yanpeng He

“…The test results showed that the layout horizon of the directional long boreholes is determined, and the layout was within the height range of 20–40 meters, clarified the relationship between the drainage data and the exposure level of the borehole and the layout of the borehole, compared the gas concentration in the upper corner of the working face before and after the drainage, and constructed a three-dimensional comprehensive drainage mode for the high-gassy working face, which provided a worth-promoting method that supports surrounding rock oil-type gas and gas treatment in the high-gas mining area.…”

Analysis of the Error Sensitive Direction and Establishment of the Equation of Face Gear Tooth Surface with Error by Ming Xingzu, Li Mande, Wang Wei, Zhao Lei

“…Based on the theory of multi-body system and the principle of gear meshing,according to six-axis five linkage gear CNC machine structure and the actual conditions of grinding,the grinding tooth surface equation of face gear with error of six-axis five linkage CNC machine is established.Through the simulation,the influence of the grinding wheel spindle kinematic pair on different error sensitive direction is analyzed,the results show that the feed axis B5 relative to machine tool bed B1 moving has larger effect on the tooth profile machining of face gear.A prejudge theory for CNC grinding to improve the machining precision and modified tooth surface error is provided.…”

Study on the Stability and Control of Gob-Side Entry Retaining in Paste Backfill Working Face by Changtao Xu, Xiangyu Wang, Dingchao Chen, Guanghui Wang, Zhenpeng Niu, Huixing Lu

“…Third, under a backfill ratio of 95%, the evolution of the abutment stress during face advancement was investigated. It was found that as the working face advanced, the backfill material and the overlying strata gradually formed a stable composite structure, with the abutment stress in the mining area stabilizing over time. …”
