The specific embodiment
Below by specific embodiment, also by reference to the accompanying drawings the utility model is described in further detail.
Please refer to Fig. 1 to Fig. 5, wherein, the structural representation of protective screening for roadway support in a kind of embodiment of Fig. 1 the utility model; 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 a kind of embodiment of the utility model; Fig. 5 is the structural representation of support system in a kind of embodiment of the utility model.
The utility model provides a kind of roadway support protective screening, for the supporting in tunnel, especially in process of coal mining, for prevent spoil alter.
In the present embodiment, roadway support comprises with protective screening: horizontal bar 1, and horizontal bar 1 is 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 metal longitudinal muscle, vertical muscle 2 includes a plurality of, whole Zong Jin 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 bending structure design along the bearing of trend of vertical muscle 2.
In said structure design, protective screening for roadway support (for convenience of description, below referred to as protective screening) by horizontal bar 1 and vertical muscle 2, formed, 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 consisting of horizontal bar 1 and vertical muscle 2 has also adopted: the bearing of trend along vertical muscle 2 adopts bending structure design, can further improve when spoil alters the buffer capacity to spoil.
The roadway support protective screening that the utility model provides, designs by said structure, by adopting metal horizontal bar 1 and vertical muscle 2 to form cancellated protective screening main body a.And in an embodiment of the present utility model, protective screening main body a adopts bending design, form L-type structure, can prevent that spoil from altering drops down onto in tunnel, and the larger impact force producing can alter to spoil time provides buffering, makes the utlity model has the good anti-channeling effect that falls.
In the utility model, protective screening main body a is L-type structure design, and protective screening main body a works out by adopting the reinforcing bar of 10mm diameter to weld, so structure design: the first, can adjust in conjunction with site work face mining height the length of " L " steel bar net; The spoil lumpiness that the second, can be caving according to work plane goaf is controlled the density of welding mesh.
The roadway support protective screening that the utility model provides, 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, there is on-the-spot decomposition easy to assembly, simple to operate, realized quick, safe and reliable feature.
High inclination-angle medium-thickness seam flexibility protect lane without coal pillar mining technology in, the roadway support protective screening that uses the utility model to provide, and cooperating face lower end and gallery top board add strong supporting, thereby replaced work plane lower end, stay and establish this distinguishing feature of large coal column.
Its advantage is mainly manifested in the following aspects:
1, protective screening main body a adopts the reinforcing bar welding that diameter is 10mm to work out, 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 being caving by " L " steel bar Wang Jiang goaf is all controlled at steel mesh reinforcement, realization is without coal pillar mining, guaranteed that flexibility protects lane simultaneously.If press reserved coal pillar exploitation, each work plane (by moving towards 500 meters, 1.7 meters of calculating of mining height) can reclaim more than 8000 tons of coals more, according to coal market price, can create more than 240 ten thousand yuan of effects.
2, roadway support with protective screening when mounted, longitudinally connects every steel mesh reinforcement, have easy to assembly, the installation strength of feature, and worker is efficiently 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 lane effect, has obtained the effect of good safety, economical, societal benefits.
In coal mining, in order to prevent the spoil in goaf, scurry 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 work plane trend, for stopping the spoil in goaf, another benefit of " L " steel bar net is, because the steel mesh reinforcement of working out has flexible feature, 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 goaf spoil pours the technical barrier in tunnel.When without coal pillar mining, adopt " L " steel bar net can effectively improve and adopt face coal recovery rate on the one hand simultaneously, reduce resources loss; " L " steel bar netting gear has Assembling convenient on the other hand, feature simple to operate, quick, safe and reliable.
Particularly, in a specific embodiment of the present utility model, 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 utility model.
In the present embodiment, horizontal bar 1 includes and is arranged at the main horizontal bar of protective screening main body a end and is arranged at the auxiliary horizontal bar between main horizontal bar; The end of vertical muscle 2 is provided with the connecting ring 21 of ring-type, and main horizontal bar is inserted in to connecting ring 21, and is connected with connecting ring 21 by welding.Connecting ring 21 is directly molded on vertical muscle 2, thereby improves the structural strength of vertical muscle 2.Main horizontal bar is inserted in to connecting ring 21, and is welded in connecting ring 21 by welding procedure, can improve the bonding strength between main horizontal bar and vertical muscle 2, thereby guarantees that protective screening has higher structural strength, the reliability while improving its use.
The end of main horizontal bar is the bending structure for connecting between protective screening main body a.From the above, the roadway support that the utility model provides is with protective screening in being installed on tunnel time, and protective screening includes multi-disc, between multi-disc, interconnects.Its installation requirement is: avoid occurring gap between interconnective protective screening as far as possible.Therefore, by said structure, design, the bending structure by main horizontal bar end between protective screening is connected, and its connection area is larger, is not only convenient to the connection between protective screening, and its bonding strength is also higher.
Particularly, in the present embodiment, mutual butt between auxiliary horizontal bar and vertical muscle 2, and be fixedly connected by welding.
In a specific embodiment of the present utility model, horizontal bar 1 is the reinforcing bar horizontal bar 1 of diameter 10mm to 12mm.Preferably, in the utility model, horizontal bar 1 adopts 10mm reinforcing bar to make.
