Abstract: Based on the engineering practice of the 90111 Transportation flexible template gob-side entry retaining,combined with the stability of the surrounding rock and the special process optimization of the hard roof. The hard roof of the top working face was suspended. To deal with the problem, optimize the construction process of the flexible template gob-side entry retaining and optimize the parameters of the roadway. The effect of practice is well. The various supporting and flexible template gob-side entry retaining achieve the desired results and achieve good economic benefits.
