摘　　要：对双鸭山七星矿一处软质、天然级配(d max<5 cm,未经破碎加工)煤矸石燃渣,进行初步的基本试验研究。目的是初步了解原岩中含煤量较高的煤矸石燃渣,直接应用在低等级公路结构层中,以节约资源和降低工程造价的可行性。试验所用燃渣集料,原岩含煤量较高,煤矸石燃渣性状类似于煤渣,颗粒强度较低(石料质地较软)。This time a preliminary basic experimental study was carried out on a soft,natural gradation(dmax<5 cm,not crushed)coal gangue combustion residue in Qixing Mine,Shuangyashan.The purpose is to preliminarily understand the feasi-bility of coal gangue combustion residue with high coal content in the original rock,and directly apply it in the low-grade high-way structure layer to save resources and reduce project cost.The slag aggregate used in the test has a high coal content in the original rock,and the properties of the coal gangue slag are similar to coal slag,and the particle strength is low(the stone is softer).

关 键 词：煤矸石燃渣 天然级配 强度
