Abstract
In view of the difficult problem of insufficient support resistance of hydraulic support existing in the fully mechanized mining face of Jinjitan Coal Mine,taking the 08103 working face of the 4th coal seam as the engineering background,based on the basic mining conditions of the working face,the stable support performance of the hydraulic support is analyzed and calculated using methods of theoretical calculation,numerical simulation,and comprehensive analogy analysis.According to the principle of improving the recovery rate of the working face,combined with the subsidence amount of the working face roof controllable range,the height of the hydraulic support is determined to be 4.9-7.5 m.The minimum support strength of the hydraulic support calculated by the self weight method is 1.44 MPa,which is verified by comparing the numerical simulation results with the theoretical calculation results in the surrounding mining area.Analyze the adaptability degree of different hydraulic supports to the coal mine environment,and determine the ZY21000/38/82D two column shield type fully mechanized top coal caving hydraulic support with a support strength of 1.45 MPa and a working resistance of not less than 21000 kN for the support of the large mining height fully mechanized working face,ensure safe and smooth mining of the fully mechanized mining face.关键词
