The long edge lap of biplate graticules, the long side of the 4th time biplate graticules and three times long edge laps of monolithic graticules, odd number time are online
For single mesh, even numbers time is biplate net on the net, the like, untill the formation of working face passage, edge being netted since the 4th time
The short side direction for graticules connects tendency steel wire rope, and the top of tendency steel wire rope is connected with the top that the 4th time is netted long side, from the
Seven times nets start to connect along the long side direction on graticules top and move towards steel wire rope, and working face has been cut after 8 knife coals, often cut later one to
Two knife coals on the back timber of support on a support beam.
The lap width of the long side of second time biplate graticules and first time monolithic graticules is 200mm.
The lap position of the 3rd time monolithic graticules and second time biplate graticules is two short for second time graticules
The center that the top of time monolithic graticules of the central junction line on side, i.e., the 3rd is located at two short sides of second time biplate graticules connects
The lap position of wiring, the 4th time biplate graticules and the 3rd time biplate graticules is the center of two short sides of the 3rd time graticules
The top of time biplate graticules of connecting line, i.e., the 4th is located at the central junction line of two short sides of the 3rd time monolithic graticules, according to
It is secondary to analogize.
The support beam is ∏ types beam or long plate-girder.
The spacing of the tendency steel wire rope is 900mm.
The spacing for moving towards steel wire rope is 300mm.
All graticules short side overlap joints are 500 mm, and the base of orlop net must be caught on during networking.
The beneficial effects of the utility model are as follows：
The utility model solves the problem of roof cracking when online is adopted at end, is that the recovery hydraulic support in later stage creates bar
Part, good effect is have received through practice test, and 5309 working faces split run highest under the conditions of breaking roof reclaimed 12 liquid
Support is pressed, complete 129 hydraulic supports of working face are reclaimed within 6 days.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model support beam connection diagram；
Wherein：First time monolithic graticules of 1-；Second time biplate graticules of 2-；The 3rd time monolithic graticules of 3-；4- is inclined to
Steel wire rope；5- moves towards steel wire rope；6- support beams；7- hydraulic supports.
