针对煤矿区煤矸石堆积，污染环境，堵塞河道，易造成地质安全等问题，谋求将煤矸石用于栽培基质的主要物料和低产土壤的改良剂。基于煤矸石在栽培基质中应用的可行性为主要研究目标，分别以采自陕西彬县、神木煤矸石为材料，研究了煤矸石的比重、斥水特性及改良措施与效果，结果表明：彬县和神木两地的煤矸石比重分别为1．89 g·cm-3和2．06 g·cm-3；神木煤矸石具有轻微斥水性，掺混6．31％以上的农田耕层土壤就能达到消除斥水性的目的；而彬县煤矸石具有严重斥水性，需用0．2％的湿润剂溶液喷洒煤矸石，就能达到消除斥水性的障碍，且效果较为持久。由此得出结论是，就煤矸石的物理性状而言，尽管存在着不同的斥水性障碍，但通过一定的改良，就可具备在栽培基质中使用的可行性。

In view of the problems of gangue stacking ,environmental pollution ,blocking rivers and causing geologi-cal safety ,explored the gangue for the main material of cultivation matrix and low-yield soil amendment .Based on the main research goal of the feasibility for gangue being used in cultivation matrix ,collected gangue from Binxian and Shen-mu as for materials , has researched the specific gravity , water repellency , improving technology and effect for the gangue .The results showed that :The specific gravity were 1 .89 g·cm-3 and 2 .06 g·cm-3 ,respectively ,for the gangue from Binxian and Shenmu .The Shenmu gangue had slight water repellency ,and the water repellency could be eliminated by mixed more than 6 .31% cultivated soil .However ,the Binxian gangue had serious water repellency ,and needed mix-ing 0 .2% wetting agent solution ,the water-repellence could be eliminated ,also had a longed lasting improving effect . Accordingly ,as for the physical characteristics of gangue ,it had feasibility to use gangue in the cultivation matrix by a certain improvement although it had various degree of water repellency .
