摘　　要：主要介绍了液动冲击螺杆马达与配套的ZYWL-6500DS定向钻机在鑫运煤矿的使用情况。通过瓦斯抽放孔施工,证实液动冲击螺杆马达在施工超硬岩石时比普通液动马达效率更高,平均单班进尺不低于30 m。解决了煤矿在硬岩(f>8)钻进中速度较慢的问题。施工结果表明,液动冲击螺杆马达比同类型的孔底马达在钻进速度和成孔率方面有着明显的优势。Mainly introduced the use condition of hydraulic impact screw motor and supporting ZYWL-6500DS directional drilling rig in Xinyun coal mine.Through the construction of gas drainage holes,it is confirmed that hydraulic impact screw motor has higher efficiency than ordinary hydraulic motor in construction of superhard rock,and the problem of slow drilling speed in hard rock(f>8)in coal mine has been solved.The construction results show that the hydraulic impact screw motor has obvious advantages in drilling speed and hole formation rate compared with the same type of bottom hole motor.
