Study and Application on the Parameters of Gob-Side Entry Retaining in Thin Seam with Limestone Roof

Advanced Materials Research, 2011
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 ...
