摘　　要：针对我国西南地区煤田水文地质条件复杂,煤矿水害的探测技术研究与实践不足的问题,开展了音频电透视探测技术在滇东矿区的研究与实践。研究了音频电透视探测技术的理论基础、技术特点、施工方法等;在滇东能源雨汪煤矿一井采煤工作面开展了音频电透视探测技术的工程实践,可靠地探测到了采煤工作面内部及其顶底板100 m高度范围内富水区、地质构造带等地质异常体的位置、分布及含水性强弱等,经钻探验证,探测成果可靠性高,为雨汪煤矿一井采煤工作面水害防治工作提供了可靠的地质依据,音频电透视探测技术为雨汪煤矿一井精准治理矿井水害,实现绿色安全开采提供了技术支撑,研究与实践取得的音频电透视法视电导率值等参数,填补了滇东矿区音频电透视探测技术研究与实践的空白,可为类似地质条件下矿井水文地质条件分析提供借鉴,具有一定的理论和现实意义。In view of the complicated hydrogeological conditions of coal fields in southwest China and the lack of research and practice on the detection technology of coal mine flood,the research and practice of audio electric perspective detection technology in eastern Yunnan mining areas were carried out.The theoretical basis,technical characteristics and construction methods of audio electric perspective detection technology were studied.The engineering practice of audio electrical perspective detection technology was carried out at the first coal mining face of Yuwang Coal Mine in Diandong Energy.The location,distribution and water content of geological abnormal bodies such as water-rich area and geological structural belt within 100 m height of the top and bottom of the coal face were reliably detected.The drilling verification showed that the detection results were highly reliable.It provides a reliable geological basis for the prevention and control of the flood in the coal face of the first well of Yuwang Coal Mine,and provides technical support for the precise control of flood in the first well of Yuwang Coal Mine and the realization of green and safe mining.The parameters such as the apparent conductivity value of the audio electrical perspective method obtained by research and practice fill the blank of the research and practice of the audio electrical perspective detection technology in the eastern Yunnan mining area.It can provide reference for the analysis of mine hydrogeological conditions under similar geological conditions and has important theoretical and practical significance.
