摘　　要：研究采动裂隙椭抛带的基本性质及其采空区瓦斯运移的规律,可以采取有效措施进行瓦斯治理。根据五阳煤矿7601综采工作面上覆岩层的特性与工作面在推进过程中的矿压显现特征,确定了采动裂隙带的高度、切眼上方椭抛带的高度、采动裂隙椭抛带内煤与岩碎胀系数,并计算出其渗透率。该研究为建立数值模拟的分析模型提供依据。Identifying the basic properties of mining fissure elliptic paraboloid zone and gas delivery law governing goaf represents an effective measure to control gas.According to the actual situation of 7601 Wuyang fully mechanized caving face and mine pressure characteristics occurring in the process of mining operation,this paper defines the height of mining fissure elliptic paraboloid zone,the weight of mining fissure elliptic paraboloid zone above open-off cut,the coal and rock the hulking coefficient in mining fissure elliptic paraboloid zone and the gives the permeability.The study provides the basis for developing analysis models for numerical simulation.
