Embodiment 1

[0018] Embodiment 1: the present invention regards bolting design as a dynamic process that changes with surrounding rock conditions, mainly comprising the following steps:

[0019] (1) Collect the basic geological and production data of the roadway, test the physical and mechanical properties and in-situ stress level of the surrounding rock of the roadway, and establish a basic database for bolt support design;

[0020] Carry out a comprehensive geomechanical survey of the mine, systematically test the physical and mechanical properties of the roadway surrounding rock and the level of in-situ stress, and obtain the basic geomechanical parameters required for bolt support design.

[0021] (2) Use the intelligent expert system to evaluate the geomechanics of the surrounding rock of the roadway, evaluate the stability level of the surrounding rock of the roadway, and obtain the relevant parameters required for the bolt support design;

[0022] The evaluation of surrounding rock ...

Abstract

The invention discloses a method for intelligently designing the bolting of coal mine tunnels, which belongs to the method for designing the bolting of the coal mine tunnels. The design method comprises the following steps of: collecting the basic condition data of the tunnels, testing the physical and mechanical properties and ground stress level of surrounding rocks of the tunnels and establishing a bolting designing basic database; performing geomechanical estimation on the surrounding rocks by utilizing an intelligent expert system to obtain parameters required by the bolting design; establishing a bolting scheme and a parameter reasoning, computing and optimizing model by utilizing the intelligent expert system, and determining an initial design scheme; performing field construction and monitoring and feeding monitoring information back to the intelligent expert system; and judging the rationality of the initial design scheme by utilizing the intelligent expert system, performing necessary correction, and cyclically performing field construction, monitoring and verification on the corrected design until final design is formed. In the method, the problems of coal mine bolting material waste, poor tunnel safety and the like are solved, and orientation to the field engineering technical personnel can be achieved; and the method is widely practicable.

Description

technical field [0001] The invention relates to a method for designing coal mine roadway bolt support, in particular to an intelligent design method for coal mine roadway bolt support. Background technique [0002] Bolt support is a systematic project, which involves various aspects such as design, construction, support materials, and actual measurement techniques. 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. If the bolt support form and parameter selection are unreasonable, two extremes will often be caused, that is, either the roadway support strength is not enough to effectively control the deformation of the surrounding rock, which will lead to accidents such as roof fall and partial side of the roadway; If it is too high, it will not only waste support materials, but also reduce the tunneli...
