一、煤岩学作为一门独立的学科,它的发展直接取决于煤在工业中的工艺用途。在十九世纪,煤主要用作为动力燃料,因此,煤岩工作者解决煤的成因问题。随着焦炭化学生产部门的发展,对于作为工艺原料的煤的须要增加了,这就决定了煤岩学中的一个新的发展方向:把煤岩成分与煤的工艺性质紧密地联系起来。 二、煤岩工作者所查明的煤的性质与显微组份成分的关系,成为研究煤岩定量法的原因。 三、煤岩成分复杂的煤层中的煤,在薄片和光片中的煤岩定量,并不都是十分可靠的。此外,用氧化的和十分破碎的煤来制作薄片和光片,会有很大的困难,实际上常常是不可能的。 四、廿世纪卅年代所提出的、在用粉碎煤的颗粒所制成的煤砖光片中进行煤岩定量的方法(阿莫索夫,瓦尔茨,施塔赫,裘列姆),对于煤岩学的工艺方向的发展,具有决定性的意义。 五、这个方法的主要优点如下: 1)可以研究任何用途的煤样; 2)制作煤砖光片的煤在样品缩分过程中选取; 3)煤砖可用氧化的和十分破碎的煤来制作; 4)煤砖光片的制作很简单; 5)可以研究任何变质程度的煤。 六、所进行的实验证明,这方法具有很高的精度(±3%)。 七、采用统一的、显微组份的名称、煤砖制作的方法和统计的条件,有助于广泛归纳和确定腐植煤成因分类的主要指标。 八、在地质勘探工作过 First, coal and rock science as an independent discipline, its development depends directly on the use of coal in the industrial process. In the nineteenth century, coal was mainly used as a power fuel, so coal and rock workers addressed the cause of coal formation. With the development of the chemical production sector in coke, the need for coal as a raw material for processing has increased, and this has led to a new development in coal petrology: the tight correlation between coal and rock composition and the technological properties of coal. Second, coal and rock workers identified by the nature of the relationship between the composition of the micro-components and become a reason for the quantitative study of coal and rock. Third, the composition of coal and coal rock complex coal, in the flake and light film in the quantitative coal, not all are very reliable. In addition, the production of flakes and sheets from oxidized and very broken coal can be very difficult and practically impossible. Fourth, the method of quantifying coal and rock in coal brick tiles made from particles of comminuted coal (Amosov, Waltz, Stach, and Juliet), proposed in the twentieth century, The development of the technology of coal and rock science is of decisive significance. Fifth, the main advantages of this method are as follows: 1) coal samples for any purpose can be studied; 2) coal for making coal brick light chips is selected during sample fractionation; 3) coal bricks can be made from oxidized and very broken coal ; 4) the production of coal brick light sheet is very simple; 5) can study any degree of deterioration of coal. Six, the experiments carried out that this method has a high accuracy (± 3%). The use of uniform names of microscopic components, the methods of making coal briquette and the conditions for statistics will help to broadly summarize and determine the main indicators of the genetic classification of humified coal.
