Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] Aiming at the problems of poor stability of the existing support structure and the like, the invention provides a roadway frame type advance support structure and method.

[0035] Such as figure 1 As shown, the support structure includes a single hydraulic prop 1, a semicircular pipe hoop 2, a steel pipe 3, a steel plate 4, a bolt 5 and a π-shaped steel beam 6, and both ends of the steel pipe 3 are welded with a semicircular pipe hoop 2, a steel plate 4 Both ends are welded with semicircular pipe clamps 2, such as Image 6 As shown, the steel pipe 3 is fixed on the single hydraulic prop 1 through a semicircular pipe collar 2 and bolts 5 to form a lateral support structure, as shown in Figure 7 As shown, the steel plate 4 is fixed on the single ...

Abstract

The invention provides a tunnel frame type advance timbering structure and method, and belongs to the technical field of mine underground safe timbering. According to the method, single hydraulic props, Pi-shaped steel beams, semi-circular pipe hoops, steel (iron) tubes, steel plates (sheets) and bolts are mainly used for being connected and combined to form a transverse supporting structure and a longitudinal connecting structure which are used for advance timbering, conventional scattered timbering structures are connected to one another transversely and longitudinally to form a whole advance timbering structure, stability is improved greatly, the shortcoming that the traditional advance timbering structure only has effective timbering strength in the perpendicular direction, and is weak in deformation resistant ability in the horizontal direction and the longitudinal direction is overcome, when a rock burst disaster occurs, a safe space can be formed effectively, and safety of operators can be guaranteed powerfully.

Description

technical field [0001] The invention relates to the technical field of mine underground safety support, in particular to a roadway frame type advance support structure and method. Background technique [0002] Rockburst is one of the most serious disasters in coal mines in the world. Before the occurrence, there is generally no macroscopic omen, but the coal and rock mass is thrown suddenly, sharply and violently, causing damage to the support, roof collapse of the roof, and roadway collapse. Blockage, injury to personnel, causing construction personnel to be injured by smashing, falling, crushing, and even suffocation due to roadway blockage. At present, with the continuous increase of coal mining depth in our country, rock burst disasters are becoming more and more serious, which poses a great threat to the safe production of coal mines and the life safety of the majority of coal mine workers. Roadway support is the components or other measures taken to support, strengthe...
