摘　　要：针对厚煤层放顶煤开采的实际,改原有平行煤层钻孔为倾向注水钻孔,充分利用采煤工作面超前支撑压力影响,对工作面煤壁支撑区附近的注水孔进行复注,从而有效降低工作面产尘量,改善井下作业环境。Aiming at the top coal caving in thick coal seam, the author proposes the inclined water injection drilling instead of the original parallel seam drilling, and repeated injection in injection hole near the support area of coal wall based on the influence of advanced abutment pressure at mining face, which will reduce the dust arising and improve the underground working environment.
