摘　　要：针对东周窑矿地质构造特征与煤层赋存条件,采用煤层可采性指数、厚度变异系数、夹矸特征值为主要参评因子,运用数理统计方法、多层次模糊数据评价理论对煤层稳定类型进行划分,为煤矿合理部署开采工作面,提质增效提供技术保障。According to the geological structure characteristics and coal seam occurrence conditions of DongzhouyaoMine,using the coal seam exploitable index,thickness variation coefficient,gangue characteristic value as the mainevaluation factors,the coal seam stability type is divided by using the mathematical statistics method and the multi-level fuzzy data evaluation theory,it provides the technical support for mining working face and improving quality andefficiency.
