Description

Cooperative control method, equipment and medium for surrounding rock of internal-tightening external-explosion roadway Technical Field The invention relates to the technical field of roadway surrounding rock control, in particular to a method, equipment and medium for cooperatively controlling an internal-tightening external-explosion roadway surrounding rock. Background Coal mine roadways are used as key infrastructure for mine production, and often face the problem of large deformation of surrounding rock under the conditions of deep mining or heavy mining of thick coal seams. The deformation is mainly caused by high ground stress concentration, stratum weakness, mining disturbance and other multi-factor coupling, so that the tunnel roof is sunk, two sides are converged and the bottom plate is raised, and the mining safety and the production efficiency are seriously threatened. In the prior art, roadway support mainly depends on single or combined measures such as anchor rods, anchor ropes or sprayed concrete, but the methods have obvious limitations. For example, traditional anchor bolt supports have insufficient pretightening force (usually less than 50 kN), initial deformation and crack expansion of surrounding rock are difficult to effectively inhibit, and blasting pressure relief technology can release far-field stress, but is easy to cause local damage and lacks cooperative optimization with near-field supports. The roadway still has deformation, the support life is shortened, and the economic loss is huge. Therefore, there is a need for precise regulation and deformation inhibition of the surrounding rock stress environment. Disclosure of Invention The invention aims to solve the technical problem of how to efficiently and safely control the surrounding rock of an internal-tightening external-explosion roadway. The invention solves the technical problems by the following technical means: the invention provides a cooperative control method for surrounding rocks of an internal-tightening external-explosion roadway, which is characterized by comprising the following steps: acquiring roadway geological exploration data of roadway surrounding rock, and constructing a geological model according to the roadway geological exploration data; dividing the roadway surrounding rock into an anchoring area and a pressure relief area according to the geological model; And respectively and alternately controlling the anchoring area and the pressure relief area by using preset control parameters. The invention also provides processing equipment which is characterized by comprising at least one processor and at least one memory in communication connection with the processor, wherein the memory stores program instructions which can be executed by the processor, and the processor calls the program instructions to execute the method for cooperatively controlling the surrounding rock of the tight-in and tight-out roadway. The invention also provides a computer readable storage medium, which is characterized in that the computer readable storage medium stores computer instructions, and the computer instructions enable the computer to execute the method of the method for controlling the surrounding rock of the inner-tightening outer-explosion roadway in a cooperative manner. The invention has the advantages that: According to the invention, the roadway surrounding rock is divided into the anchoring area and the pressure relief area, the self-supporting capacity of the rock body is enhanced through the high pretightening force strong support in the anchoring area in the control parameters, the pressure relief area is blasted outside to relieve pressure, the integral stress of the surrounding rock is reduced, and the 'internal fixation and external release' synergistic effect of deformation control is realized, so that the stress environment of the surrounding rock is accurately regulated and controlled and deformation is restrained.
