The specific embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Please refer to Fig. 1 to Fig. 5, wherein, the roadway support structural representation of protective screening in Fig. 1 an embodiment of the present invention; Fig. 2 is the structure for amplifying schematic diagram at A place in Fig. 1; Fig. 3 is the structure for amplifying schematic diagram at B place in Fig. 1; Fig. 4 is roadway support interconnective partial structurtes schematic diagram between protective screening in an embodiment of the present invention; Fig. 5 is the structural representation of support system in an embodiment of the present invention.
The invention provides a kind of roadway support protective screening, be used for the supporting in tunnel, especially in process of coal mining, be used for preventing spoil alter.
In the present embodiment, roadway support comprises with protective screening: horizontal bar 1, and horizontal bar 1 is the metal horizontal bar, horizontal bar 1 includes a plurality of, whole horizontal bar intervals and arranges and be parallel to each other; Vertical muscle 2, vertical muscle 2 is the metal longitudinal muscle, vertical muscle 2 includes a plurality of, whole vertical muscle intervals and arranges and be parallel to each other; Vertical muscle 2 is connected with horizontal bar 1 and is formed with cancellated protective screening main body a, and protective screening main body a adopts the bending structure design along the bearing of trend of vertical muscle 2.
In the said structure design, roadway support with protective screening (for convenience of description, below referred to as protective screening) formed by horizontal bar 1 and vertical muscle 2, horizontal bar 1 and vertical muscle 2 adopt metal make and be formed with net structure, and it has higher elasticity and structural strength.And the protective screening main body a that consists of horizontal bar 1 and vertical muscle 2 has also adopted: the bearing of trend along vertical muscle 2 adopts the bending structure design, can further improve when spoil alters, to the buffer capacity of spoil.
Roadway support protective screening provided by the invention, design by said structure, by adopting metal horizontal bar 1 and vertical muscle 2, forms cancellated protective screening main body a.And in one embodiment of the invention, protective screening main body a adopts the bending design, form the L-type structure, can prevent that spoil from altering drops down onto in tunnel, and the larger impact force that produces can alter to spoil the time provides buffering, makes the present invention have the good anti-channeling effect that falls.
In the present invention, protective screening main body a is the L-type structure design, and protective screening main body a works out by the reinforcing bar welding of adopting the 10mm diameter, so structure design: the first, can adjust in conjunction with site work face mining height the length of " L " steel bar net; The second, can control according to the spoil lumpiness that the work plane goaf is caving the density of welding mesh.
Roadway support protective screening provided by the invention, its width can be in conjunction with the difference of adopting surface pressure, the difference of the array pitch between work plane anchor pole, Anchor reinforced support of bringing, adjust the width of " L " steel bar net, has on-the-spot decomposition easy to assembly, simple to operate, realized quick, safe and reliable characteristics.
High inclination-angle medium-thickness seam flexibility protect lane without the coal pillar mining technology in, use roadway support protective screening provided by the invention, and cooperating face lower end and gallery top board add strong supporting, stay and establish this distinguishing feature of large coal column thereby replaced the work plane lower end.
Its advantage is mainly manifested in the following aspects:
1, to adopt diameter be that the reinforcing bar welding of 10mm is worked out to protective screening main body a, the spoil that its intensity is caving much larger than goaf rushes to the impulse force at steel mesh reinforcement place, more than the spoil that goaf is caving by " L " steel bar net all is controlled at steel mesh reinforcement, realization is without coal pillar mining, guaranteed that simultaneously flexibility protects lane.If press the reserved coal pillar exploitation, each work plane (by moving towards 500 meters, 1.7 meters calculating of mining height) can reclaim more than 8000 tons of coals more, according to the coal market price, can create more than 240 ten thousand yuan of effects.
2, roadway support with protective screening when mounted, vertically connects every steel mesh reinforcement, have easy to assembly, the installation strength of characteristics, and worker efficiently is lower.
3, with protective screening in actual applications, effect is fairly obvious in roadway support, has banned work plane lower end Coal Pillar Design, has improved coal recovery rate, has guaranteed that flexibility protects the lane effect, has obtained the effect of safety, economical, societal benefits preferably.
In coal mining, for the spoil that prevents goaf is scurried in tunnel, the technical measures of taking are that the flexible steel mesh reinforcement of " L " type that the reinforcing bar of employing diameter 10mm is worked out is arranged in lower end along the work plane trend, be used for stopping the spoil in goaf, another benefit of " L " steel bar net is,, because the steel mesh reinforcement of working out has flexible characteristics, can well alleviate the impact force of the spoil that goaf is caving.
Adopt " L " steel bar net and necessary when adding strong supporting and having substituted the exploitation of high inclination-angle medium-thickness seam reserved coal pillar play roof supporting and stop that the goaf spoil pours the technical barrier in tunnel.Adopt simultaneously " L " steel bar net can effectively improve and adopt the face coal recovery rate on the one hand without coal pillar mining the time, reduce resources loss; " L " steel bar netting gear has Assembling convenient on the other hand, characteristics simple to operate, quick, safe and reliable.
Particularly, in a specific embodiment of the present invention, vertical muscle 2 designs for wavy shaped configuration.The design of employing wavy shaped configuration, can improve the deformability of indulging muscle 2, so can make protective screening absorb more impact force, improves impact resistance of the present invention.
