摘　　要：在采用地球物理资料时,技术人员必须充分利用采矿工程师丰富的实践经验和对现场情况的了解,将地球物理资料与已知地质资料、水文地质资料相结合,进行综合分析利用。生产期间一旦发现水患险情,需及时采取应急措施,以确保生产安全。唐家会矿项目61304工作面采用音频电透视法,探测工作面底板下0~80 m范围内的富水异常区分布范围及其强弱。控制工作面走向长2 100 m,原始数据质量符合《煤炭电法勘探规范》要求,完成了合同任务。采用音频电透视法在61304工作面内探测时未发现较为明显的富水异常区,采用音频电透视法探查61304工作面(长×宽=2 100 m×240 m)底板下0~80 m范围内富水性异常区分布范围及相对强弱,对比注浆前后音频电透视成果,分析工作面底板注浆加固效果。In the application of geophysical data, technicians must make full use of the rich practical experience of mining engineers and their understanding of field conditions, and combine geophysical data with known geological data and hydrogeological data for comprehensive analysis and utilization. Once the danger of flooding is found during production, emergency measures shall be taken in time to ensure production safety. The 61304 working face of Tangjiahui Coal Mine project adopted audio-frequency electrical penetration to detect the distribution range and strength of water-rich abnormal areas within 0-80 m below the floor of the working face. The strike length of the working face was controlled to be 2 100 m, and the quality of the original data met the requirements of Coal Electricity Exploration Code, which fulfilled the contract. No obvious abnormal water-rich area was found in 61304 working face by using audio-frequency electrical penetration. Audio-frequency electrical penetration was used to explore the distribution range and relative water-rich abnormal areas within 0-80 m below the floor of 61304 working face(length × width =2 100 m × 240 m). This paper compared the results of audio-frequency electrical penetration before and after grouting, and analyzed the grouting reinforcement effect of the working face fllor.
