地质雷达超前探测在常村煤矿的应用研究

    Advanced detection application by using geological radar in changcun coal mine

    • 摘要: 巷道掘进前方隐伏的灾害源极易造成矿井事故的发生,对煤矿的安全生产构成了极大的威胁。对掘进巷道进行超前探测,从而掌握掘进巷道的煤层异常情况具有十分重要的意义。本文首先介绍了基于地质雷达方法的煤巷超前地质探测方法和原理,然后从实际工程应用出发,对潞安集团常村煤矿皮带顺槽反掘巷进行地质雷达超前地质探测。应用基于时间剖面和频率剖面复合解释技术对处理后的数据进行解释,结果表明:探明了反掘巷侧帮及迎头面地质构造情况、确定了6个煤/岩性变化带、2个破碎和裂隙水区域的位置和深度。

       

      Abstract: Disaster source in front of the tunnel face can easily cause the coal mine accidents,resulting in a great threat for the safe production in coal mine.It is of important significance for the advance detection to obtain the information of the disaster source and seam anomalies.This paper introduces the advance detection method and principle based on the geological radar,then a detection application case is conducted in the belt trough reverse-driving-lane of the Changcun coal mine,Lu’an Group.The processed data are interpreted by using the complex technology of the time profile and frequency profile,and the results show that:the geological structure of the side and head face in the reverse-driving-lane is acquired,and the location and depth information of the 6 coal-lithology belt change zones and 2 fracture water areas are determined.
