| Abstract: | During the coal mine work process,there must be a support device for the working face within 20 m of the safety exit section of the coal face in each section and the roadway interface.A large-step advance support hydraulic support design scheme was proposed,so as to solve the support problems of complex sections such as the two ends of the section and the rectangular and trapezoidal flat lanes.Through simulation experiments,testing of support strength and bearing pressure,the validity of the design was verified,the expected design goals were achieved.The efficiency of underground operations was improved,and the requirements for safe production were guaranteed. |
