摘　　要：本文概述了京西浅层小煤窑采空区的分布情况和现状,指出京西门头沟发展规划过程中小煤窑探测的必要性,从分析小煤窑采空区的地球物理场特征入手,研究了不同物探方法在小煤窑采空区探测中的适宜性。通过圈门的工程实例展示了高密度电法、瞬变电磁法及多道面波法的应用效果,总结了不同物探方法的优缺点,证明了工程地质勘察中采用综合物探法取得完整、准确探测结果的必要性和有效性,提出应用中出现的问题并给出了解决的建议,同时强调了物探与钻探综合地质解释的重要性。The present situation of shallow coalfield mined-out areas in Western Beijing is described. It is pointed out the necessity of prospecting the coalfield in the process of planning and development of Mentougou.From the aspect of geophysical field characteristics,the suitability of different geophysical methods in the prospecting is analyzed. Through the engineering example in Juanmen,the application effects of high-density resistivity method,the TEM and the MASW are revealed,and the advantages and disadvantages of different methods are summarized. It is proved the necessity and effectiveness of using comprehensive geophysical methods to get integrated and accurate results in engineering geological investigation. The problems in the application and the corresponding recommendation are put forward, and the importance of combining geophysical exploration with drilling to get integrated geological interpretation is emphasized.
