摘要
通过测定煤矸石在不同容重下的饱和体积含水量、总孔隙度、非毛管孔隙度、毛管孔隙度、饱和导水率来分析容重对煤矸石水力特性的影响,为采煤塌陷地土地复垦提供一定的理论依据。
In order to analyze the effect of bulk density on gangue hydraulic characteristics,measured the volume of saturated moisture content, total porosity ,capillary porosity ,non-capillary porosity and saturated hydraulic conductivity of coal gangue in different density. It can provide certain theoretical basis for coal mining subsided land reclamation.
