The invention provides a roadway roof and floor bulging control method based on a runoff erosion geological environment, relates to the technical field of roadway support, and can solve the bulging treatment problem of the running water erosion geological environment. The method comprises the steps that roadway roof drilling pressure relief is conducted; grouting is conducted on a crack gap or a crack of a roadway floor; rock plates are arranged on the surface of a roadway roof and the surface of the roadway floor; and an inverted arch support is laid on the rock plate of the roadway floor. The roof is drilled for pressure relief, so that stress concentration of the roof is avoided; grouting is carried out at the crack or the crack gap of the floor, and the floor is temporarily controlled to swell; and the rock plates are arranged on the surfaces of the roof and the floor, the roof and the floor are reinforced through the rock plates, the integrity of the floor and the roof is guaranteed, the bulging occurrence time can be stopped or delayed, and bulging can be treated in a fixing mode of the rock plates after bulging of the roof or the floor occurs.
Description
technical field [0001] The present disclosure relates to the field of roadway support, in particular to a roadway roof and floor swelling control method based on flowing water erosion geological environment. Background technique [0002] Affected by the geological structure of the geological environment eroded by running water, the overall surrounding rock of the mine is relatively soft. For the mine roadway, due to the long exposure time of the roadway and the influence of the surrounding coal seam mining, the deformation of the top and bottom of the roadway is serious, the bottom plate of the roadway is easy to bulge upward, and the roof of the roadway is easy to bulge downward. [0003] The bulge of the roof and floor of the roadway, especially the bulge of the floor of the roadway, will bring certain unsafe risks to normal production. It will not only hinder transportation, pedestrians or ventilation, but also cause the closure of the roadway section in serious cases, po...
