Study on Support Optimization of Coal Face Passing through Super-high Gob Roadway
In order to solve the problem that the hydraulic support can not connect the roof of the super-high gob roadway,the support technology of"anchor rope hanging shed+wooden crib+one beam and two columns"is adopted to solve the problem that the support can not connect the roof of the super-high gob roadway and the destruction deformation of the gob roadway.The results of ground pressure observation and support resistance change after gob roadway support optimization show that this support technology can effectively prevent gob deformation and solve the problem of support roof connection,the high strength support has the similar support strength compared with the solid coal,and can meet the requirements of gob roadway entry.
