摘　　要：针对下沟煤矿硬厚煤层的特点,试验了一种顶煤深孔快速定向成孔及快速装药的工艺方法。该法对硬厚煤层顶煤弱化提供了必要的技术支持。According to the characters of hard-thick coal seam in Xiagou mine, a test was carried out to analyse the technique of the directional hole-forming and the projectile filling in long-borehole of the top-coal, which provides the technical support for the top-coal avianize. The technique has the generalization and application value for top-coal avianize under the same geological conditions.
