Coal quality and coal price matching method and device

Abstract

The invention relates to the field of coal production and sales, particularly to a coal quality and coal price matching method and device, which solve the technical problem that at present the coal quality is not matched with the coal price during the entrucking process. The coal quality and coal price matching method is realized through the following steps: (a) establishing a quantitative relation between coal price and coal quality analysis indexes; (b) detecting the coal quality in real time and pricing; and (c) entrucking and pricing the coal. The coal quality and coal price matching method comprises a vehicle automatic identification and entrucking system, a level gage, a coal quality analysis meter and a computer system. According to the coal quality and coal price matching method and device, the coal market price and the coal quality are combined to match the coal price so as to obtain a regression equation between the coal price and the coal quality, as a result, the coal price is closely related to the actual coal quality; and a coal bunker is divided into a plurality of layers with same volume, so that the coal valuation is more accurate.

Description

technical field [0001] The invention relates to the field of coal production and sales, in particular to a coal quality and coal price matching method and device. Background technique [0002] At present, coal sales generally go through the following steps: warehouse storage of finished coal, loading into trucks, evaluation of coal quality, and determination of coal price based on quality. When the current sales pricing system calculates the coal price, several samples are extracted on the vehicle for analysis after loading, and the price is set according to the quality of the coal obtained after the analysis. [0003] The price of coal is closely related to its quality. For different coal varieties, their prices are not the same. The most important factor affecting coal quality is calorific value, which characterizes the basic properties of power coal and is the main technical index for calculating fuel consumption, thermal efficiency and pricing. In addition to calorifi...

Problems solved by technology

However, since the composition of the coal in actual production cannot be completely consistent with the composition of the published coal type, the loading price can only be determined by selecting a coal type that is closest to the average value of the sample quality (coal quality analysis index) Therefore, it will bring a large calculation error; in addition, when sampling, only a few samples can be taken on the surface of the coal that has been loaded, and the sampling error is large, which makes the error between the coal price and the actual coal price larger; Since the coal quality is analyzed only when the truck is loaded, the coal quality analysis will lag behind the coal sales work, which will bring a lot of inconvenience to the coal price settlement
