摘　　要：根据钻孔资料和矿井生产资料 ,对研究区二叠系 13- 1#煤层空间分布特征进行趋势面分析 ,并通过方向变化性来研究煤层的稳定性状况。结果表明 :煤层底板具东北部高 ,西南部低 ;煤层厚度由东北向西南逐渐变厚 ,厚薄条带沿倾向相间分布 ;煤层稳定性由北向南逐渐趋于稳定 。Based on considerable borehole and production data, a trend-surface analysis has been undertaken on the space distribution trait of the Permian seam 13-1 in the target area, and also the method of orientation variability was proposed to study the stability of No.13-1 coal seam. The results show that the shape of No.13-1 coal-seam floor is higher in northeast and lower in southwest; the thickness of coal-seam is thickened from northeast to southwest, and the thick and thin coal-seam distribute interlace following the inclination of coal-seam; the stability is becoming better along north-south, and the compatibility of comprehensive mining is also becoming better.
