摘　　要：文章介绍了地震CT探测原理,并以平朔井工一矿4108综放工作面为背景,将地震CT技术应用于采煤工作面超前支承压力分布状态的确定,通过对比波速CT成像与现场煤岩体实际条件及常规矿压理论,验证了探测结论的可靠性,为采煤工作面矿压规律的研究提供了一条新途径。The paper introduced the seismic CT detection principle.Base on the No.4108 fully mechanized top coal caving mining face in Pingshuo No.1 Underground Mine as the background,The seismic CT technology was applied to determine the distribution status of the pilot support pressure in the coal mining face.In comparison with the wave speed image and the site coal and rock actual condition as well as the mine normal strata pressure theory,the reliability of the detection conclusion was verified to provide the a new access to study the mine strata pressure law of the coal mining face.
