A kind of soft and strong bearing construction structure and construction method for gob-side entry retaining roadway

Abstract

The invention discloses a gob-side entryretaining roadway-side flexible and high-strength material bearing construction structure and a construction method thereof, and relates to the technical field of gob-side entryretaining roadway-side support structure. The gob-side entryretaining roadway-side flexible and high-strength material bearing construction structure comprises a flexible and high-strength material bearing construction structure, a booster pump and a gas pressurizing room, wherein the flexible and high-strength material bearing construction structure comprises rubber air bags, paste cement, wood point pillars, single support columns, filling templates, articulated roof beams, preserved rod bodies, a front filling baffle and roof bolts, wherein the rubber air bags are connected with the booster pump; the booster pump is connected with the gas pressurizing room; a filling area formed by the filling templates and the front filling baffle is filled with the paste cement. According to the gob-side entryretaining roadway-side flexible and high-strength material bearing construction structure and the construction method thereof, provided by the invention, the construction mode of gob-side entryretaining filling bodies is optimized, the air bags on an upper layer can provide active support for top plates, reduce roof separation, relieve action of impact dynamic load to a roadway-side support, body, and are applicable to given deformation caused by top plate movement under the condition that the support strength is maintained or even improved; the filling body on a lower layer can provide support force when a main roof is stable, and completeness of the roadway-side support structure can be ensured.

Description

technical field [0001] The invention relates to the technical field of support structures for sideways of gob-side entry retention, in particular to a flexible and strong bearing construction structure for sideways of gob-side entry retention and a construction method thereof. Background technique [0002] Gobside retaining, as a pillar-free roadway protection technology, is in line with the development requirements of my country's coal industry and is an important direction of my country's coal mining because of its advantages of alleviating the tension of excavation replacement and realizing "Y" ventilation. focus on. [0003] The load-bearing structure next to the gob-side entry retention is the key to ensure the success of entry retention. Through a lot of research on the movement process of the roof of the gob-side entry retaining, it is found that the load-bearing structure of the roadside should not only bear the "given deformation" caused by the subsidence of the bas...
