@@@@According to the occurrence condition of coal seams of Yangdong coal mine, the gob-side entry retaining technology of the first lib-erated seam face is put forward. The gas control measures of working face and the holing between heading face and roadway of gob-side entry retaining is summarized. Practice has proved that it is of great significance in saving tunneling project amount, improving the recovery rate of coal resources and solving the outburst of the upper coal.
