Embodiment Construction

[0009] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0010] The embodiment of the present invention is based on engineering and hydrogeological survey data, and obtains a three-dimensional evaluation model reflecting the quality of ore in the mining area through the establishment of solid models of different lithology regions, the establishment of evaluation index block models, and the interpolation of indexes. Using a more scientific method to classify the surrounding rock in the mining area reasonably and effectively is of great significance for the reasonable support planning of the mining area.

[0011] figure 1 The flow chart of the method for automatically grading and partitioning the rock mass provided by the embodiment of the present invention includes the following steps:

[0012] Step 101, prepare raw dat...

Abstract

The invention discloses a method for performing grading and sectionalizing on rock mass automatically and relates to the technical field of mining. The method includes: preparing primary data, and creating a restrain rock mass model based on the primary data; building a block model on the basis of the restrain rock mass model, analyzing indication distribution rules in the block model to generate a variation function, and selecting an indication valuation method; creating a search spheroid, and building valuation parameters according to the indication valuation method; performing valuation on the indications by means of the selected indication valuation method based on the valuation parameters and the variation function to determine the grade of rock quality; and according to the rock quality grading results, setting different colors on small blocks in different ranges according to the block model. By means of the method, a three-dimensional evaluation model for reflecting rock quality of a mining area can be obtained based on engineering and hydrogeologic survey data. By means of the method, reasonable and efficient grading on mining surrounding rock can be performed scientifically, and the method has significant meaning on reasonable supporting planning.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a method for automatically grading and partitioning rock masses. Background technique [0002] Reasonable and effective grading and partitioning of surrounding rocks in mining areas, especially soft rocks, has always been the focus and difficulty of mine roadway support. If the existing method is used to classify and partition the rock mass and then support it, the roadway will be damaged to a large extent, and the rate of abandoned roadway and bad roadway will be relatively high. This is mainly due to the rigid evaluation index of the traditional rock mass grading and zoning method, which cannot be flexible, and cannot be effectively combined with the specific reality of the mine when used. Therefore, it is of positive and important significance for the mine support work to adopt the rock mass classification and partition method that can take into account the actual situation of...
