| 摘 要： | 煤层层滑构造会引发煤层性质变化,进而影响煤矿安全开采。为此基于层滑构造发育的地质特征,应用反射波运动学以及动力学研究方法,对煤矿已揭露地质信息与地震剖面进行对比,研究煤层层滑构造的地震响应特征。通过分析层滑构造在不同地震属性下弹性波运动学及动力学特征及其变化规律,确立不同地震信息响应特征与层滑构造之间的关系。基于层滑构造所引发的煤层变化及地震响应变化规律,利用多信息融合技术解释区域内煤层厚度变化规律、划分构造煤发育带,进而圈定层滑构造区域。

| Abstract: | The coal seam interlayer gliding tectonics can initiate coal seam property variations and then impact coalmine safe working.Therefore,on the basis of interlayer gliding tectonics development geological characteristics,using reflection wave kinematics and dynamics research method have carried out comparison between revealed geological information and seismic sections;in view of the above studied coal seam interlayer gliding tectonics seismic response features.Through analysis of interlayer gliding tectonics elastic wave kinematic and dynamic features and variation patterns under different seismic attributes have established relationship between different seismic information response features and interlayer gliding tectonics.Based on interlayer gliding tectonics initiated coal seam variations and seismic response variation patterns,using multi-information integration technology has interpreted coal seam thickness pattern in the region,partitioned tectonoclastic coal zones,and then jointly delineated interlayer gliding tectonics district range. |
