Abstract

The invention discloses a stope overlying strata load three-dimensional model construction method, and relates to the technical field of model construction, and the method comprises the following steps: obtaining a sample data scatter diagram based on the sample data of a to-be-detected overlying strata; obtaining a first stress threshold value and a second stress threshold value based on the sample data scatter diagram; obtaining a stress representation value by the first stress threshold and the second stress threshold; acquiring a stress change function based on the stress representation value; obtaining a to-be-detected overlying strata to obtain and generate data points; acquiring a first detection point based on the generated data point; obtaining a real-time substitution value based on the first detection point and the stress change function; function fitting stress is obtained based on the stress change function and the real-time substitution value, and a stope overlying strata load three-dimensional model is generated based on the function fitting stress; the method is used for solving the problem of low accuracy of stope overlying strata load three-dimensional model construction caused by low accuracy of obtaining stress at an undetected position of an instrument in an existing model construction technology.
