Abstract

The invention relates to the roadway surrounding rock control technology field, in particular to a construction method capable of controlling roadway deformation. The construction method capable of controlling the roadway deformation includes a roadway driftage and dynamic pressure influence preceding stage construction method and a back production constant dynamic pressure influence stage construction method, wherein the roadway driftage and dynamic pressure influence preceding stage construction method includes: drilling holes in a stress concentration area, and forming a pressure release area; and performing anchoring support on a roadway superficial layer surrounding rock area; and the back production constant dynamic pressure influence stage construction method includes: drilling holes in an area far away from the surface of a roadway to form a pressure release area; performing surrounding rock grouting modification on the other area closer to the surface of the roadway than the pressure release area; and performing anchoring support on the roadway superficial layer surrounding rock area. The construction method capable of controlling the roadway deformation enables multiple measures to jointly come into play, reduces influence from an impact dynamic load to the space in the roadway to the utmost, reduces the deformation of the roadway to the utmost, and guarantees a roadway escape space after dynamic disasters occur and reduces quantities of injuries and deaths of personnel on the premise of reducing occurrence rate of risk brought by the dynamic disasters of roadwayimpact ground pressure and the like.

Description

technical field [0001] The invention relates to the technical field of roadway surrounding rock control, in particular to a construction method for controlling roadway deformation. Background technique [0002] With the gradual deterioration of coal mining conditions, more and more roadways have experienced complex conditions such as complex structures, deep high stress, weakness, and mining, and support has become increasingly difficult. Affected by the mechanical properties of coal and rock and mining, dynamic phenomena such as rock burst or strong mine pressure appear in many roadways, which are manifested as areas near the front of the roadway excavation or areas affected by dynamic pressure, frequent coal blasting or roof rock formations, and even occurrence The dynamic load shock waves generated by disasters such as rock bursts cause impact damage to the roadway space, and the space is reduced or even closed. [0003] This type of roadway goes through two main stages:...
