摘　　要：运用数理统计方法定量分析煤层的稳定程度,对确定勘探区的煤层稳定类型,合理布置勘查工程中的勘探工作量有着重要意义。通过选用不稳定指数、煤层厚度、变异系数、可采性指数等四个指标,对内蒙古新上海一号井田十层可采煤层的稳定性进行定量性评价,结果与实际勘查工作中确定的煤层稳定程度基本相符。Analyzing coal seam stability quantitatively through the mathematical statistics has major significance in exploration works to confirm exploration area coal seam stability type, workload layout reasonably in exploration engineering. Through selection of four indices of instability index, coal seam thickness, coefficient of variation and mineability index, quantitatively assessed stability of 10 mineable coal seams in Xinshanghaimiao No.1 minefield, Inner Mongolia; the results are basically in line with coal seam stability identified in practical exploration works.
