Article Preview

The gob-side entry retaining technology can be used to not only solve the problem of intensity in successive mining but also reduce the 10,000 tons' drivage rate and improve the coal recovery. Based on the established roof cutting mechanical model, the method of numerical simulation is used to determine the technical parameters of gob-side entry retaining in one coal mine. The reduction in cross-section of the roadway is 10.8% according to the field observation, which shows that the gob-side entry retaining has obtained preferable results and fulfilled the demand of safe production in the face.
