摘要
煤田勘探地球物理开创于本世纪３０年代，７０年代打破长期徘徊的局面，８０年代获得迅速的发展，物探方法取得较好的地质效果，在国民经济中作出应有的贡献．本文全面介绍煤田地球物理勘探的各种方法技术．随着装备的更新，加速了技术的发展，例如，高精度重力和磁力探测，航磁资料的精细处理、交直流电法技术的提高、ＣＳＡＭＴ方法在推复体下找煤、高分辨率地震勘探技术迅速发展、数字测井仪参数测量精度提高及多种新方法的探索、一批新设备、新震源的研制及投入使用，使煤田物探工作在综合地质勘探中发挥愈来愈重要的作用，取得较好的地质效果与经济效益．
Geophysical exploration of coal came into the world early in the 1930's. Only in the 1970's, it had broken through its long jogging situation and started developing. The fall in oil price has given it a series of hard hits in the 1980's. At the same time, the geophysical exploration of coal in China has been developing rapidly.During this period, the equipment have renewed and technology developed, for instance, high sensitivity gravity and magnetic survey, more precision of aeromagnetic data,advanced techniques of AC and DC electric methods, more coal deposites beneath the thrust structure found by CSAMT, fast expediting the technology of high resolution exploration of coal seismic methods, digital well log systems with high precision level and some new parameters, new methods, being found and used in many geological applications, a number of new equipment and new seismic sources being approved and applied in every field.
