Automatic intelligent design and optimization system for anchor bolt support of coal tunnel

Abstract

The invention relates to an automatic intelligent design and optimization system for an anchor bolt support of a coal tunnel. The system comprises a tunnel surrounding-rock index obtainment and stability classification subsystem, an anchor bolt support parameter intelligent-matching subsystem and a support design verification and optimization subsystem, wherein the tunnel surrounding-rock index obtainment and stability classification subsystem realizes the classification and evaluation of tunnel surrounding-rock stability by processing data input by a user or calling parameters in relevant knowledge bases; the anchor bolt support parameter intelligent-matching subsystem establishes a training model based on a sample tunnel training BP (Back Propagation) neural network in an internal knowledge base of the system to realize the intelligent matching of anchor bolt support parameters of the coal tunnel; the support design verification and optimization subsystem implements theoretic checking calculation based on a suspension theory, a combined beam theory, a combined arch theory and an energy theory according to the anchor bolt support parameters obtained by the anchor bolt support parameter intelligent-matching subsystem, and automatically analyzes various support schemes to select the support scheme which meets the deformation requirements of tunnel surrounding-rocks, wherein the selected support scheme being the optimal support scheme is recommended to the user. By applying the system, the scientificity and the reasonability of the anchor bolt support structure and parameters are effectively guaranteed; the reliability of an anchor bolt support system is improved; the healthy development of an anchor bolt support technique for the coal tunnel in our country is promoted.

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...

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
