Description
technical field
[0001] The invention belongs to the technical field of transportation lanes, and in particular relates to a method for improving transportation lanes. Background technique
[0002] The continuous mining operation of underground mines will break the original stress balance, and there will be obvious mine pressure phenomenon in the roadway in the mining area of the working face, and it will show a continuous cycle of periodic changes with the advancement of the working face. The support and maintenance of the roadway often need to be continuously optimized and adjusted according to the actual production, and the stability of the roadway is tested through the mining practice. Generally speaking, after the roadway is excavated, the rock mass around the roadway will be in a state of equilibrium and the stress will be redistributed. , thus causing the deformation of the surrounding rock of the roadway. If this deformation cannot be effectively controlled, the roa...
