Practices on Selection and Application of Hydraulic Powered Support for Fully Mechanized Coal Mining Face
Abstract：In order to select a hydraulic powered support suitable for mining conditions of the coal mining face in No. 15 seam of Jincheng Mining Area and to realize the mine high production and high efficiency, based on the application experiences of the ZZ6000/17/32 mode hydraulic powered support applied in No. 15 seam mining of Wangtaipu Mine and the mine strata pressure observation information, the powered support stressed conditions in No. 2306 coal mining face of the mine were studied when the immediate roof initially fell down, the main roof initially pressurized, the main roof pressurized periodically and pressurized non-periodically. A study and analysis on the insuffi- cient rated working resistances of the support in the coal mining face and the problems existed in the powered support were conducted. The results showed that the ZY10000/16/32D mode two legs shield powered support selected for the coal mining face would have good suitability to the mining conditions of No. 15 seam in the mining area.
