摘　　要：在露天与地下联合开采时期,控制地表漏风主要通过露天坑底铺设覆盖层来实现。为研究覆盖层与漏风之间的关系,通过实验室相似模拟试验,对7种粒径岩石颗粒的孔隙率及覆盖层的漏风特性进行了研究,并对试验数据拟合确定了孔隙率与覆盖层高度的关系,得出了漏风系数、漏风量与覆盖层厚度的方程,为矿山企业确定合理覆盖层高度提供了理论依据。During joint mining of open-pit and underground,the ground air leakage control was realized by laying the capping layer on the open pit. In order to study the relationship of air leakage with the capping,the porosity of the rock in seven kinds of particles sizes and the air leakage characteristics of the capping were studied and the relationship between the porosity and the capping height were determined by the laboratory analogue simulation tests, obtaining the function of the air leakage coefficient, amount of air leakage and the capping height. It provides the theoretical basis for determining the cap- ping height for mine enterprises.
