The invention discloses a coal mine working face top plate high position directional drill hole group pressure relief gas extraction method. According to the principle, the coal mine working face topplate high position directional drill hole group pressure relief gas extraction method comprises the steps that before a working face is stoped, by constructing a high position directional drill holegroup along the working surface in an air return way of the working surface, main hole sections of high position directional drill holes are extended in an O-shaped circle fissure zone of a goaf formed after the working face is stoped, and lower position drill holes are appropriately lowered at the position of open-off cut close to the working face, crossing branch holes facing upward are constructed in upper position drill holes, after the working face is mined by adopting the combining extraction of all drill holes, gas guiding of the fissure zone is carried out, and pressure relief and desorption of gas in the fissure zone are carried out. The coal mine working face top plate high position directional drill hole group pressure relief gas extraction method can play a dual role of reducing the gas concentration in the corners of the working surface and in the return current and extracting high-concentration gas in the pressure relief and desorption zone of the goaf, gas control of theworking face is achieved, and the recycling of gas resources is realized.
