摘　　要：矿井勘探方法中,槽波地震是探测小构造最重要的一种方法,小构造的定量探测对于工作面的设计和开采具有重要的意义,通过透反射联合勘探并以揭露信息进行约束能够取得准确的结果.对山西龙泉矿4203工作面进行槽波透反射勘探,巷道的煤厚为6.8 m,巷道揭露的断层f29落差为7 m, f30落差为11.8 m,利用椭圆切线法和透射层析成像信息得出槽波的解释成果,从构造发育规律和三维地震解释的断层的数量、延伸长度、走向进行统计分析,合理推断槽波探测断层在工作面内外分布及延伸长度,并通过钻探得到了验证,得出在有效利用先验地质资料条件下矿井槽波地震透反射法具有广泛的应用前景.In the method of mine exploration, the channel wave seismic is the most important method to detect small structures, the quantitative solve the small structural distribution in the working face have great significance for the design and mining. With the two methods combine and use the information to expose the information as the constraints often achieve expected demands. Transmission and reflection exploration were carried out on the 4203 working face mining in Shanxi Longquan mine. Thickness of coal seam from roadway is 6.8 m, the drop of the fault f29 and f30 in the roadway is respectively 7 m, 11.8 m. Though the ellipse summation method and transmission information obtained the interpretation results, and link the regularity of tectonic development and the number, extension length and trend of some faults from three-dimensional seismic data were statistical analysis. Though the Method of combining 3 D seismic and technology of Channel wave seismic, It is reasonable to deduce the distribution of faults in and out of the working face and verify it through drilling. It is found that the elliptic tangent method can define the fault plane position very well with the high signal-to-noise ratio channel wave. The method is fast and accurate, and sometimes the result can be determined by using only one shot gather date. It has a significant effect on predicting the fault position in the working face. Combined with prior geological information, channel wave seismic transmission and reflection method can distinguish fault attribute characteristics, improve interpretation accuracy of small faults, and reevaluate three-dimensional seismic results that derives the design of the mining working-face and the comprehensive geological reinterpretation of mining areas. Technology of Channel wave seismic transmission and reflection method based on Evaluation of Three-dimensional seismic geological data have good application prospects.
