摘　　要：煤层顶板岩层含砂率是影响瓦斯质量体积的重要因素之一,本文利用相关分析和逐步逼近的方法,确定统计的煤层顶板厚度,提出了改进的含砂率表达方法——煤层顶板岩层效应厚度影响系数,从而实现了对煤层顶板岩层"含砂率"的准确计算.该研究方法可以在其它矿井中推广应用.Sand content rate of coal seam roof is one of the most important factors which influences the gas content in coal seam. By using the method of correlation analysis and pregressive approximation, the correct coal seam roof thinkness was decided. A new expressed method of sand content rate, that is influence coefficient of coal seam roof strata thinkness was put forward. The sand content rate was calculated correctly, and method can be used in other coal mines.
