Intelligent recommendation and dynamic optimization method for deep roadway support scheme

Abstract

The invention discloses an intelligent recommendation and dynamic optimization method for a deep roadway support scheme, and the method comprises the steps: carrying out the correlation analysis of engineering geological parameters of a deep supported roadway, building a sample database, and dividing support levels according to the thickness of a loose circle; then sequentially establishing a loose circle thickness prediction model based on random forest regression, multiple linear regression and a support vector machine, and selecting an optimal prediction model through comparison of evaluation indexes of the prediction model; predicting the support level of the roadway to be supported by adopting the optimal prediction model, intelligently recommending a support scheme, inverting the engineering geological parameters after the scheme is implemented through a roadway peripheral displacement monitoring technology and a rock mechanics inverse analysis method, readjusting the support level and dynamically optimizing the support scheme. The method is easy to implement and easy and convenient to operate, the deep roadway engineering geological conditions can be comprehensively and specifically considered, the supporting design scheme is reasonably and rapidly recommended, and supporting mode parameters are dynamically adjusted in real time.

Description

technical field [0001] The invention belongs to the support technical field of geotechnical engineering and mining engineering, and in particular relates to an intelligent recommendation and dynamic optimization method suitable for deep roadway support schemes. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Coal, iron ore and other mineral resources, as one of the main natural resources in our country, occupy a very important position in our country's natural energy production and consumption structure. In recent years, with the rapid development of my country's economic construction, the shallow mineral resources are increasingly depleted, which requires the economical exploitation and utilization of the existing deep mineral layers, and the development of deeper mineral resources. However, due to the complex geological conditions such ...
