摘　　要：坑透综合曲线图是分析工作面内地质异常的基本图件,用于分析地质异常范围边界及地质异常的性质。结合淮南矿业集团的5个综采工作面具体情况,对工作面煤厚及宽度变化对坑透综合曲线图的影响进行了分析研究。结果表明:1工作面煤厚影响坑透实测场强接收值的大小。煤厚越大,实测场强值越高;煤厚越小,实测场强值越低。2工作面宽度影响坑透实测曲线及理论场强曲线的弧度。工作面宽度越小,其曲线弧度越大,表现为中间高、两侧低;工作面宽度越大,其曲线弧度越小,实测场强曲线往往近似于水平线或水平锯齿状线。3场强差值曲线近似于零值水平线,其形态不受煤厚及面宽变化影响。The comprehensive curve charts of radio-wave penetration are the basic plots for analysis of geological anomalies within coalfaces.The influence of coal seam thickness and coalface width are studied in detail from the data of five coalfaces in Huainan coal mining corporation.The results are as follows：①The thickness of coal seam affects the received field strength values of radio-wave penetration.The thicker the coal seam,the higher the received field strength values;and the thinner the coal seam,the lower the field strength values;②The width of coalfaces affects the radian values of measured and theoretical field strength curves.The narrower the coalface,the greater the radian value of curve,showing high in the middle and low on both sides.The wider the coal face,the smaller the radian value,yielding an approximate horizontal line;③The difference curves of field strength are near the zero,which are nearly unaffected by coal seam thickness and working face width.
