摘要
钻孔偏移是矿井防治水工作中面临的重要技术问题之一。依据全方位钻孔测斜仪对刘一井田6号煤层底板注浆钻孔的测斜结果进行研究,对比分析了设计和实际钻进的差异。研究结果证实了测斜工作在煤矿防治水工作中的重要作用,并且通过总结钻孔偏斜规律,为以后提高钻探工程的准确度和效率提供依据。
Borehole deviation was one of the most important technical problems in mine water control. According to research application of omnibearing borehole inclinometer in inclinometer results of bottom grouting borehole in No.6 coal seam of Liuyi shaft area, the difference between design and actual drilling was contrasted. The results confirmed the important function of inclinometer work in coal mine water prevention and control work. At the same time, the regularity of borehole deflection was summarized, which provided a basis for improvhag accuracy and efficiency of drilling engineering in the future.
