Abstract

The invention discloses a method for reserves computation, which is realized through the following steps: based on the grid method, and through the adoption of the Kriging method and the surfer gridded data, contour line data is generated through the data conversion function, computation parameters are assigned to all grid cells through the mapgis software, and the spatial overlay technology is adopted for the overlapping with the computed grid range. The method overcomes the problem that the selection result of reserves computation parameter control data, such as coal-seam thickness and rock stratum dip angle, is affected by human factors.

Description

Technical field

[0001] The patent of the present invention relates to a method for calculating coal resource reserves by combining space overlay technology with GIS grid method. Background technique

[0002] The calculation method of mineral resource resources / reserves refers to the estimation of underground mineral deposits based on the geological information obtained in the process of geological exploration (including mining) of mineral deposits. [1] . It is a basic work in the process of coal development, and the reliability of its results is directly related to the risk of coal mine investment, the rationality of coal mine production decisions, and the effectiveness of daily work. At present, in inclined and gently inclined coal seams, coal resource reserves are calculated using methods such as block method and grid method, which are all calculation methods based on paper drawings. Although the use of computers has increased the accuracy of the resource / reserve calcula...
