在瓦斯含量极高的煤层（厚）和不同地层段涌水的超厚水敏性地层中钻进施工，合理设计钻孔结构、选择设备、钻进方法、钻进参数和正确操作，是顺利完成钻进施工的前提，正确使用泥浆是孔内事故预防措施的关键。正确使用“高密度”水基成膜泥浆，既能保持孔内液柱与孔壁之间的压力平衡，也能降失水抑制水敏性地层水化膨胀和分散脱落，从而达到防止孔壁坍塌，起到稳定孔壁的作用。介绍了这些技术措施在贵州扬寨煤矿高瓦斯涌水超厚煤系复杂地层中的应用及效果。

In high gas coal measure and ultra thick water sensitive formation with water gushing in different formations, ra-tional design of borehole structure, selection of equipments, drilling methods, drilling parameters and correct operation are the premise of successful completion of drilling operation.And the correct use of slurry is the key for prevention of hole ac-cidents.By proper application of high density water-based film forming mud, the pressure balance between liquid column and the hole wall can be kept and hydration expansion and dispersion breaking off can also be inhibited by fluid loss control in water sensitive formation to prevent the collapse of hole wall and realize the stabilization.The paper introduces the appli-cation of these technical measures in complex formation of high gas ultra thick coal measure with water gushing of Yangzhai coal mine in Guizhou and the application effects.
