Problems solved by technology

However, the vitrinite reflectance of coal measured in actual use varies widely. How to deal with the graph of vitrinite reflectance has become a bottleneck that restricts us from issuing inspection reports.

Embodiment 1~7

[0059] Embodiment 1~7 is the random reflectance distribution map of coal vitrinite group

Embodiment 1

[0061] Such as Figure 1 ~ Figure 2 As shown in , the tail-like graph is continuously drawn, and the part with a small percentage content, smooth, and just about to peak is deleted.

Embodiment 2

[0063] Such as Figure 3 ~ Figure 4 As shown, when there is only one main peak with a high percentage content, all the discontinuous peaks with a small percentage content can be removed.

Abstract

The invention relates to a coal petrographic analysis test and graph processing method. The method adopts a digital coal petrographic analyzer to determine the vitrinite reflectance of coal, and according to the final graphics, deletes the scattered part that has a percentage content close to 0, smooth image and rising peak and is affected by interfering components, thus ensuring that the determined graph reflects the true components of coal. Compared with the prior art, the method provided by the invention can truly reflect the quality of coal provided by a supplier, more objectively reflect the real situation of coal so as to better serve coking and iron-making production, meets the fined large-scale production needs of companies, and provides more real and accurate data.

Description

technical field [0001] The invention relates to the technical field of inspection and testing, in particular to a coal lithofacies analysis inspection and graphic processing method. Background technique [0002] For the analysis of incoming coal, the traditional method is to judge whether it meets the requirements of the corresponding coal type based on the coal work index, but there is no ability to judge whether it is a single coal type or whether there is a mixed coal phenomenon in the incoming coal. Using the fully automatic digital coal rock analyzer MY6000, it can automatically measure the vitrinite reflectance of the coal, and then judge the type of coal (single, simple mixed, complex) through graphic analysis and combined with the coal index Mixing), so as to determine whether there is coal mixing. However, the vitrinite reflectance of coal measured in actual use varies widely, and how to deal with the graph of vitrinite reflectance has become a bottleneck restricti...
