摘　　要：为解决现阶段煤矿井下探放水中存在的问题及安全隐患,以山西天地王坡煤业有限公司为例,通过分析煤矿井下工作面探放水作业钻孔施工的特点,研制了一种钻杆扶正器,用来辅助钻机开孔施工。该设备可以有效地控制钻杆,减少钻杆摆动幅度,保证开孔时钻头可以快速切入煤体,同时保证在整个施工过程中钻孔精度。经过现场实践,所获得的结果和反馈基本符合预期效果,验证了该设备的可靠性和安全性,同时也为同类条件下探放水钻孔及瓦斯抽采钻孔施工提供了技术设备借鉴。In order to solve the problems and safety hazards of underground water exploration and drainage in coal mines at the present stage,taking Shanxi Tiandi Wangpo Coal Industry Co.,Ltd.as an example,a drill pipe centralizer was developed to assist the drilling hole construction by analyzing the characteristics of drilling water exploration and drainage operation in underground working face of coal mines.The equipment can effectively control the drill pipe,reduce the swing amplitude of the drill pipe,ensure that the drill bit can quickly cut into the coal body when opening the hole,and ensure the drilling accuracy during the whole construction process.Through field practice,the results and feedback obtained are basically in line with the expected results,which verifies the reliability and safety of the equipment,and also provides technical equipment reference for the construction of water exploration and drainage boreholes and gas drainage boreholes under similar conditions.
