摘　　要：为适应矿井建设时采区地震勘探检测煤层厚度的需要，从煤层具有地震勘探中“薄层”特点出发，建立煤层反射波数学表达式在频率城直接反演，并采用可减少非煤厚因素影响的谱平方比法检测煤厚，取得良好效果，可达到煤矿建设要求。n order to adapt the need of mine construction for the coal seam thickness detection by seismic exploration in mining area,and proceed from the characteristic of coal seam as a 'thin layer'in seismic exploration,the mathematical expression of coal seam reflected wave is established,and directly inversed in the frequency domains The coal seam thickness is detected by the spectral square ratio method which can reduces the effects of non-thickness factors,the good effectiveness is obtained,and the requirement of mine construction can been achieved.
