近钻头电磁波随钻测量技术在井下定向钻探过程中，可提供孔底附近岩层的自然伽马值，从而对钻孔揭露的煤层、煤层顶底板岩性以及陷落柱、裂隙等构造进行有效识别。本文针对峰峰矿区地质条件复杂、陷落柱和裂隙等构造隐伏且无规律，以及采掘作业安全需求与构造精度探查不足的问题，通过研究无线随钻伽马测量技术，结合近钻头电磁波技术，以峰峰集团孙庄矿126402工作面为例，优化了该技术在非取芯钻孔中的应用。研究过程中，在井下定向钻探中实时获取钻头位置信息，并对周围岩性进行精准判定。结果表明，该技术能够高效识别煤层、顶底板岩性及陷落柱、裂隙等构造，提高了井下地质、水文地质、瓦斯探查钻孔的钻探成果质量，提升了隐伏地质构造的预测预报能力，为煤炭安全高效开采提供了地质保障。

 In the process of underground directional drilling, the near-bit electromagnetic wave measurement while drilling technology can provide the natural gamma value of the rock layer near the bottom of the hole, so as to effectively identify the lithology of the coal seam, the roof and floor of the coal seam, the collapse column and the fracture exposed by the borehole. Aiming at the problems of complex geological conditions, hidden and irregular structures such as collapse columns and fissures in Fengfeng mining area, as well as the safety requirements of mining operations and insufficient exploration of structural accuracy, by studying the wireless gamma measurement technology while drilling, combined with the near-bit electromagnetic wave technology, No.126402 Face of Sunzhuang Mine was taken as an example, the application of this technology in non-coring drilling was optimized. During the research process, the bit position information was obtained in real time in the downhole directional drilling, and the surrounding lithology was accurately determined. The results showed that the technology could effectively identify coal seam, roof and floor lithology, collapse column, fracture and other structures, improve the quality of drilling results of underground geology, hydrogeology and gas exploration drilling, improve the prediction and prediction ability of hidden geological structures, and provide geological guarantee for safe and efficient coal mining.
