    Research progress and application of geophysical exploration methods for water-conducting fracture zone in coal mines

    • 摘要: 煤矿导水裂隙带是煤矿开采过程中引发水害的关键因素。本研究在深入分析其形成机制、影响因素及危害的基础上,综合运用多种物探技术开展煤矿导水裂隙带探测工作,并通过实际案例验证了这些技术的有效性和可行性。研究结果显示,导水裂隙带的形成受岩层硬度、岩层组合、地质构造特征、煤层厚度、煤层倾角、含水层与隔水层分布、地下水位及水压等多种因素影响。导水裂隙带的产生与发展会引发矿井突水、瓦斯积聚、顶板坍塌等灾害,对煤矿安全生产构成严重威胁。直流电法、电磁法和岩层探测技术等多种物探手段可用于探测煤矿导水裂隙带,为煤矿安全生产提供技术支持。现有物探技术在分辨率、适用条件和数据解释方面仍存在局限性。未来随着智能化监测预警系统的发展,煤矿物探技术将更加高效地保障煤矿安全生产。

       

      Abstract: The water-conducting fracture zone in coal mines is a critical factor triggering water disasters during the mining process. This paper delves into its formation mechanism, influential factors, and impacts. By integrating multiple geophysical exploration technologies, the research explores the detection of water-conducting fracture zones in coal mines. The effectiveness and feasibility of these technologies are validated through practical case analyses. The research results indicate that the formation of water-conducting fracture zones is influenced by various factors, such as rock hardness, rock combinations, geological structures, coal seam thickness, coal seam dip angle, the distribution of aquifers and aquitards, groundwater levels, and water pressure. The emergence and evolution of water-conducting fracture zones could lead to severe mining disasters, including sudden water inrush, gas accumulation, and roof collapses, thereby posing a significant threat to the safety of coal mine production. Several geophysical exploration methods, including direct current electric method, electromagnetic method, and strata detection technology, are employed to detect water-conducting fracture zones in coal mines, offering technical support for coal mine safety. Nevertheless, existing geophysical exploration technologies still have limitations in terms of resolution, applicable conditions, and data interpretation. It is anticipated that with the advancement of intelligent monitoring and early warning systems, coal mine geophysical exploration technologies would more efficiently safeguard coal mine production safety in the future.
