| 摘 要： | 以乌达矿区为例,用精煤的产率和煤样密度组成的煤岩学方法对煤的可选性进行了评价。它的特点是实验煤样用量少,采点样多,其研究结果可以充分显示煤层三维空间上的可选性变化规律,深入了解煤中矿物质种类、分布特性等与可选性的关系,而且可以从根本上揭露影响煤炭可选性的内在因素,为选煤方法提供真实可靠的理论依据。

| Abstract: | In this paper, authors evaluate the coal washability using the petrological method of clean coal yeild and coal density consist in Wuda coalfield. The characters of the method include less amount of coal samples used and more sampling points. The result of the study can well depict the laws governing the 3 - dimensional variation of washability and understand the kind, the character of its distrilbution of minerals in coal and their relations with washability. What s more, it can also expoise the intrinsic factors which may affect the washability of coal to give the reliable theory basis for coal preparation. |
