An automatic intelligent design and optimization system for coal roadway bolt support

Abstract

The invention relates to an automatic intelligent design and optimization system for coal roadway bolt support, which includes a roadway surrounding rock index for classifying and evaluating the stability of the roadway surrounding rock by processing the data input by the user or calling the parameters in the relevant knowledge base Acquisition and stability classification subsystem; based on the sample roadway training BP neural network in the internal knowledge base of the system to establish a training model to realize the bolting parameter intelligent matching subsystem of the roadway's bolting parameter intelligent matching; according to the bolting parameter intelligent matching subsystem; The bolt support parameters obtained by the protection parameter intelligent matching subsystem are theoretically checked and calculated based on suspension theory, composite beam theory, composite arch theory, and energy theory. The required support scheme is recommended to the user's support design verification and optimization subsystem as the optimal support scheme. This system effectively guarantees the scientificity and rationality of the bolt support structure and parameters, improves the reliability of the bolt support system, and promotes the healthy development of my country's coal mine roadway bolt support technology.

Description

technical field [0001] The invention relates to a system for the design and optimization of bolt support in coal mine roadways. Background technique [0002] With the development of the coal industry, there are more and more high-yield and high-efficiency working faces in my country, and the output has increased significantly. Coal mine excavation support is a very important production link. Anchor technology is a systematic project, which involves design, construction, support materials, measurement techniques and other aspects. Bolt support design is a key technology in bolt support engineering, which is related to important issues such as the quality of bolt support engineering, whether it is safe and reliable, and whether the economy is reasonable. Due to the complexity and uncertainty of geological conditions, the selection of various parameters in support engineering design, the approximate description of various properties of rock mass and rocks, and the final evalu...

AI Technical Summary

Problems solved by technology

[0004] The current bolt support design system is cumbersome to operate, and the parameters that need to be input by users are too complicated and professional. Many data are difficult to obtain in general production sites, and users are required to have a high professional level.

This limits the promotion and use of such systems in production practice
