Discussion on comprehensive gas control model of the first mining area at the second level in Taoer mine
For the present situation that existing gas control model cannot guarantee safe and efficient production of mine, based on the reference of comprehensive gas control technologies in Huainan, a new control model, which is suitable for the mine, was explored.The model mainly uses cross-seam drilling of rock roadway in floor to pre-extract gas in coal roadway strips and arranges n+ 1 layout method of floor rock roadway, which can be used as air return airway, tail extraction roadway and gas control roadway, so one roadway has several uses can be realized.The comprehensive gas control measures of gas extraction from extracting seam by hole drilled along seam, hole drilled along roof in highly-located drilling field, pipe buried in upper corner and gob-side roadway retaining with Y type ventilation system are used to control the gas of mining face.
