摘　　要：煤田地质钻探作为一项关键的勘探活动,在揭示地下结构、矿层分布和煤田地质特征方面具有不可替代的作用。钻孔漏失问题往往会成为工程进行的一个严峻挑战,漏失的发生可能导致地下液体的渗透,不仅对钻孔的稳定性造成威胁,也直接影响到数据的准确性和地质信息的获取。文章将深入研究钻孔漏失的类型、其对煤田地质钻探的影响,以及常见问题形成的原因。同时,将着重分析发生钻孔漏失时的堵漏情况,并详细探讨预防和应对漏失的技术手段。Coalfield geological drilling,as a key exploration activity,plays an irreplaceable role in revealing underground structures,ore distribution,and coalfield geological characteristics.The problem of drilling leakage often becomes a serious challenge in engineering.The occurrence of leakage may lead to the infiltration of underground fluids,which not only poses a threat to the stability of drilling,but also directly affects the accuracy of data and the acquisition of geological information.This article will delve into the types of drilling leakage,their impact on coalfield geological drilling,and the causes of common problems.At the same time,it will focus on analyzing the sealing situation when drilling leakage occurs,and explore in detail the technical measures to prevent and respond to leakage.
