Abstract

The invention discloses a rockburst risk prediction method and system based on comprehensive attribute measurement and a medium. The rockburst risk prediction method comprises: determining evaluationindexes, evaluation grades and grading standards of rockburst risks; constructing a single-index attribute measure function of each evaluation index of the rockburst risk according to the grading standard; determining the weight of each evaluation index by adopting a frequency statistical method according to the historical rockburst data; obtaining a to-be-predicted sample, and calculating single-index attribute measurement of the to-be-predicted sample according to the single-index attribute measurement function; calculating comprehensive attribute measurement according to the single-index attribute measurement of the to-be-predicted sample and the weight of each evaluation index; and for the comprehensive attribute measure, predicting the rockburst risk of the to-be-predicted sample by adopting a confidence criterion. The evaluation model considers the complexity of underground engineering geological conditions and the uncertainty of risks, provides an effective method and way for rockburst risk evaluation, and has certain feasibility and applicability in engineering practice.

Description

technical field [0001] The present disclosure relates to a rockburst risk prediction method, system and medium based on comprehensive attribute measurement. Background technique [0002] The statements in this section merely enhance the background related to the present disclosure and may not necessarily constitute prior art. [0003] Rockburst is a typical engineering geological disaster under high ground stress conditions, which poses a serious threat to the safety of underground construction personnel and equipment. With the rapid development of water conservancy, transportation and mining projects in my country, more and more deep rock masses are excavated in high ground stress environments, and the prevention and control of rock bursts will become more and more prominent, becoming the field of deep underground engineering geological disaster prevention and control. important topic. [0004] In the process of realizing the present disclosure, the inventors found that th...
