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. In order to find out whether the highly metamorphic coal in the fire area of ​​Besikuq open-pit mine in Xinjiang has the recoverable value, and to investigate the effect of the coal and rock products in the burning area, ie, the high-quality coal after fire and the alteration rock by fire, on the slope of the open pit mine , The coal quality test, shear test and moisture content test were carried out on the highly metamorphic coal and alteration rock in the fire area of ​​the mine. The test results show that the high metamorphism coal still has great value in mining, The volcanic alteration rock turns into a distinctly weak layer in the distribution of its stratigraphic layers, and their apparent cohesion, internal friction angle and shear strength decrease obviously with the increase of water cut, which greatly affects the slope This result can provide the basis for the design of open pit slope.
