无线电波透视技术在探测极复杂底分层工作面煤厚中的应用

随着采煤机械化程度的提高，对采煤工作面的地质条件要求也越来越高，这就要求更为精确地探测工作面内的地质构造及煤层赋存情况。以往的井巷地质编录和地质分析已无法满足生产需要，而无线电波透视技术（又称坑透）具有理论成熟、施工快速简便、探测效果明显的优点，通常用来探测采煤工作面中的断层、破碎带、陷落柱、薄煤带等地质构造异常体，是煤矿中常用的一种物探勘探技术。对无线电波透视的探测机理进行了简单论述，使用多频段结合的探测方法，以实例准确地探测出复杂底分层工作面内煤厚的变化情况，划定采煤工作面内的薄煤区和相对厚煤区，为矿井的生产安排提供决策依据，避免了不必要的投入。经过实际回采的验证，取得了良好的效果，较好地指导了煤矿综采生产工作。

Application of radio wave fluoroscopy in detecting coal thickness in extremely complicated bottom layer working face

With the increase of the degree of mechanization of coal mining,the geological conditions of the coal mining face are becoming more and more demanding,which requires more accurate detection of the geological structure and the occurrence of coal seams in the working face.In the past,the geological cataloging and geological analysis of wells and lanes could not meet the production needs.The radio wave fluoroscopy technology(also known as pothole penetration)has the advantages of mature theory,fast and easy construction and obvious detection effects.Faults,broken zones,subsidence columns,thin coal zones and other geological structural anomalies are a common geophysical exploration technology in coal mines.This paper briefly discusses the detection mechanism of radio wave perspective and uses a combination of multi-frequency band detection methods to accurately detect the changes in coal thickness in a complex bottom layer working face,and delineates the thin coal area in the coal mining face.And relatively thick coal areas,provide a basis for decision-making for the production arrangements of the mine and avoid unnecessary investment.After the actual mining verification,good results have been achieved and the comprehensive production of coal mines has been well guided.
