Abstract

The invention discloses an advanced support device and method for a roadway and application of the advanced support device and method. The advanced support device comprises a stacking type advanced support group (1) mounted at the front end of the roadway close to a coal face, and a step taking type advanced support group (2) mounted at the position, away from the coal face, of the front end of the roadway far. Through the stacking type advanced support group (1), split type moving at the front end of the extending roadway of the coal face is realized; and through the step taking type advancedsupport group (2), integral moving at the rear end of the roadway is realized, so that support for a broken roadway top plate and the roadway with high pressure at a coal mining triangle area is met.

Description

technical field [0001] The invention relates to an advance support device, method and application thereof, in particular to an advance support device, method and application thereof for roadways. Background technique [0002] Advance support is one of the auxiliary measures taken to excavate ahead of the tunnel face to ensure the stability of the tunnel excavation face. Therefore, the advance support device, method and application for the roadway are an important mine device, in the existing advanced support devices, methods and applications for roadways, the main methods include pipe sheds, small conduits, and horizontal jet grouting piles, especially for broken roadway roofs and coal mining triangles with high pressure There is no advance support device, method and application thereof for the roadway. [0003] Based on the applicant's technical disclosure document and the existing technical problems, technical features and technical effects in the background technology, t...
