摘要:
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。

Abstract:
In view of the problems of gangue stacking, environmental pollution, blocking rivers and causing geological 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 Shenmu as for materials, has researched the specific gravit y, 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 mixing 0.2% wetting agent solution, the water-repellence c ould 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.
Key words:  gangue  specific gravity  water repellency  cultivation matrix  feasibility
