Research on filling wall parameters of gob roadway

On the base of TunLan mine's geology conditions, the author put forward gob roadway and Y model ventilation scheme for full mechanized mining working face. According to the need of gob roadway working face, the parameter's calculation and optimizing of roadway fill wall have been completed by analyzing the first and second mining affect and combining the rule of roof moving and mine pressure. The paper's results afforded theory basis for gob roadway technology's application, scientific solving method for gas preventing and the new idea for safe production in high gas mines.
