Abstract
The utility modal relates to a supporting device for roadway setting during roadway mining of a steep dip seam in a pillarless mining mode, in particular to a strip steel mesh for isolating the roadway behind a working face from a gob. The strip steel mesh is simple in structure, large in strength, high in toughness, and capable of effectively preventing gangue from dropping into the roadway along the inclined work face, isolating the gob from the roadway, guaranteeing operation safety of workers and providing the premise for setting the roadway successfully and safely.
Description
Technical field
The utility model relates to half-edge coal seam stope drift active workings and stays a kind of support apparatus of establishing tunnel without coal pillar mining, specifically a kind of for isolating the band steel mesh reinforcement in tunnel, work plane rear and goaf.
Background technology
At present between common adjacent coal-face, adopt the mode of reserved coal pillar to guarantee roadway support, stay the size of coal column to have obvious impact to its maintenance situation in tunnel, adopt and stay without coal pillar mining that to establish tunnel comparatively successful in nearly level and gently inclined seam application.The gentle oblique seam inclination of nearly level is less, it is little to the security threat in tunnel that goaf is caving spoil, workman easily protects lane work, but very large in half-edge coal seam difficulty, because high_dipping face seam inclination is large, along with seam mining, goaf top plate is caving spoil and sharply glides to work plane middle and lower part, scurry into tunnel, directly threaten personnel's life security of operation in tunnel.
Safety, effectively isolate goaf and tunnel, be exploitation high_dipping face without the prerequisite of coal pillar mining technology, band steel mesh reinforcement has can contracting amount moderate, Support Resistance is large, good stability, low cost and other advantages.Therefore study that a kind of supporting intensity is large, the isolation goaf of high safety is necessity with the support apparatus in tunnel.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, a kind of band steel mesh reinforcement that adopts isolation tunnel, work plane rear and goaf is provided, stop that goaf is caving spoil downslide and scurries in tunnel, for providing prerequisite without coal pillar mining at half-edge coal seam, make full use of material, cost-saving, for workman's operation provides safety guarantee.
Of the present utility model for the band steel mesh reinforcement of isolating tunnel, work plane rear and goaf as shown in Figure 1, each moves towards direction along work plane and forms by moving towards rib 1, vertical rib 2 and tendency rib 3, moves towards rib 1 and welds respectively with vertical rib 2, tendency rib 3.
Band steel mesh reinforcement top is fixed on top board, and below is fixed on base plate, and one section of the every propelling of work plane, constructs a band steel mesh reinforcement, and interception goaf is caving spoil, forms closely knit prop supporting roof.The utility model is simple in structure, and intensity is large, and toughness is high, can effectively stop that spoil scurries into tunnel along inclined cut, and isolation goaf and tunnel ensure workman's job safety, stays and establishes tunnel prerequisite is provided for success safety.
Brief description of the drawings
Fig. 1 is the structural representation in the utility model.
In figure, 1-moves towards reinforcement bar, 2-vertical steel rib, and 3-is inclined to reinforcement bar.
detailed description of the invention:of the present utility model for the band steel mesh reinforcement of isolating tunnel, work plane rear and goaf as shown in Figure 1, each moves towards direction along work plane and forms by moving towards rib 1, vertical rib 2 and tendency rib 3, moves towards rib 1 and welds respectively with vertical rib 2, tendency rib 3.
Band steel mesh reinforcement top is fixed on top board, and below is fixed on base plate, and one section of the every propelling of work plane, constructs a band steel mesh reinforcement, and interception goaf is caving spoil, forms closely knit prop supporting roof.The utility model is simple in structure, and intensity is large, and toughness is high, can effectively stop that spoil scurries into tunnel along inclined cut, and isolation goaf and tunnel ensure workman's job safety, stays and establishes tunnel prerequisite is provided for success safety.
