摘　　要：为查明新疆别斯库都克露天煤矿火烧区高变质煤是否具备可采价值,并查清火烧区火烧煤、岩产物-火烧高变质煤和火烧蚀变岩对露天矿边坡的影响作用,对该矿火烧区高变质煤、蚀变岩分别进行了煤质化验、剪切试验及含水率试验;试验结果表明:火烧高变质煤仍具有较大的开采价值,而火烧高变质煤与火烧蚀变岩在其地层层组分布中变现为明显的弱层,且随含水率增加,它们的粘聚力、内摩擦角和抗剪强度均表现明显地降低,从而极大程度影响边坡的稳定性.该结果可为露天矿边坡设计提供依据.The coal quality test, shear test and moisture test have been taken in order to find out the recoverable value of high metamorphism coal, and also, find out how the metamorphism coal and alterated rocks affect the slope of Xinjiang Biesikuduke open pit. The results show that the metamorphism coal still has its recoverable value, and metamorphism coal and alterated rocks appears obvious weak layer in the ground layer distribution,whose cohesion, friction angle and shear strength reduce obvious as there moisture increase, therefore greatly influence the stability of the slope. The results provide the basis for open pit slope design.
