Method and system for grading cavability of rock

Abstract

The invention provides a method and system for grading cavability of rock. The method comprises the steps: establishing a database of evaluation parameter vectors of all cavability grades of rock, and determining a grade mean vector of the evaluation parameter vectors of each cavability grade and a total mean vector of the evaluation parameter vectors of all the cavability grades in the database; determining a discrimination matrix for cavability grading according to the grade mean vector of each cavability grade and the total mean vector; determining a discrimination function for cavability grading according to the discrimination matrix; acquiring a cavability graded result of rock of a mine to be evaluated according to evaluation parameter vectors of the mine to be evaluated and the discrimination function. According to the method and the system, the problem in the prior art that rock cavability grading mainly depends on experience of engineering personnel is solved, the scientific evaluation of cavability of the rock of the mine to be evaluated is achieved, and a solid foundation is laid for the successful application of a natural caving method.

Description

technical field [0001] The invention relates to the technical field of mining engineering, in particular to a method and system for grading rock collapsibility. Background technique [0002] Natural caving mining is a mining method that relies on the natural caving of the rock mass itself. Compared with mining methods such as open field method and filling method, it has low cost and safe operation. A mining method comparable to surface mining, the successful application of this mining method can bring huge economic benefits to the enterprise. However, due to the difficulty in accurately judging the geological conditions of the mine area (that is, the collapseability of rocks), the wrong application of the natural caving method will cause huge economic losses. Therefore, it is of great significance to correctly judge whether the mine can successfully apply the natural caving method. [0003] Rock caving property is used to measure the difficulty of natural rock caving. The ...
