Description
Technical field
The present invention relates to a kind of coal mine roadway advance support system, particularly a kind of coal mine roadway single track handling tail becomes first formula advance support system.
Background technology
Fully-mechanized mining working lame advanced supporting is the Focal point and difficult point of coal work protection always, and by work plane mining influence, lame advanced supporting scope internal stress is large, and shrinkage strain amount in tunnel is large, and the smooth safety that advance support effect has a strong impact on coal-face advances.
Several years ago China's fully-mechanized mining working lame advanced supporting mainly adopts shaped steel metallic support, hydraulic prop joins articulated roof beam, double wooden prop adds the support patterns such as crossbeam, these support patterns workman amount of labour is large, fltting speed is slow, poor stability, backward in technique.The fast development of scientific and technological level in recent years drives coal mining efficiency to improve constantly, and on the one hand because pit mining intensity maximum improves, face propulsion speed and automaticity are had higher requirement to advance support; On the other hand, fully-mechanized mining working coal excavation apparatus volume is increasing, coal mining is highly more and more higher, because the demand such as equipment conveying and ventilation drift section is increasing, head-room is maximum reaches 4.5 meters, Breadth Maximum reaches 6 meters, and the increase of drift section size and work plane mining influence bring larger difficulty jointly to ahead work face supporting.
At present, having achieved roadway workface at coal in China main producing region part Modern Pit adopts long distance two column hydraulic supports to carry out advance support, long distance two column advance timbering move mode adopts monolithic to move frame, reach the even longer advance timbering of 20m with advance of the face integral forward lead, each unit advance is 1.6m to the maximum, move frame each time all once to support the back generation within the scope of advance support, the advance support of 20m length supports nearly 13 times repeatedly to back, after back and bolt-mesh-anchor support system bear the repeated multiple times support of back timber, easily cause roof destruction and bolt-mesh-anchor support thrashing, have a strong impact on advance support effect, up to the present, using hydraulic support to carry out, advance support thoroughly avoids repeatedly supporting is the difficult problem never solved.
Summary of the invention
In order to improve modernization high yield and high efficiency mine lame advanced supporting quality, realize using hydraulic support to carry out nothing and repeatedly support advance support, the invention provides a kind of coal mine roadway single track handling tail and become first formula advance support system, this system can not only ensure safe and reliable lame advanced supporting effect, thoroughly avoid the drawback of existing advance support system repeatedly roof supporting, and can push in it high-yield and high-efficiency demand adapting to Modern Pit fast.
The present invention realizes the technical scheme that its technique effect adopts:
Single track handling tail of the present invention becomes first formula advance support system, comprises the advanced automatic moving type in a kind of tunnel and supports hoisting machine, it is characterized in that: also comprise unit supports formula hydraulic support, movable girder steel, single track slip crane and track accessories thereof.Described system is moved towards to be arranged in center line in roadway both sides correct position along work plane by two column unit hydraulic chock-shield supports, and can conveniently set up girder steel and attachment rail, advance support length determination unit hydraulic chock-shield support quantity needed for work plane, erection activity girder steel between the two frame unit supports formula hydraulic support top beams that left and right is relative, under movable girder steel, install single track slip crane runway, single track slip crane can run in orbit before and after roadway direction, the head and the tail of the left and right two column unit hydraulic chock-shield support arranged in both sides, tunnel respectively arrange that 1 automatic moving type supports hoisting machine, and stem hoisting machine hoisting mechanism is arranged backward, and afterbody hoisting machine hoisting mechanism is arranged forward, cooperating face coal mining progress, first afterbody track section is pulled down, then afterbody two unit supports formula hydraulic supports are dropped to extreme lower position, to be sling tail units hydraulic chock-shield support, movable girder steel be positioned in the middle part of tunnel in single track slip crane scope capable of hoisting by described tail support hoisting machine, slip crane successively by near the tail units hydraulic chock-shield support of work plane, movable girder steel and the handling of single track slip crane runway to advance support system header (ahead work face supporting foremost), advance support system afterbody (near work plane end) left and right supports and to move forward coal mining progress in cooperating face after hoisting machine completes lifting function and complete advance support to tunnel, then the hoisting machine being arranged in the support system stem left and right sides moves forward the space abdicating arrangement unit hydraulic chock-shield support, the unit supports formula hydraulic support being transported to stem by single track slip crane by the support hoisting machine handling of arranging about stem to both sides, tunnel correct position, and rise left and right two frame unit supports formula hydraulic supports connect top after movable girder steel between the frame unit supports formula hydraulic support top beam of left and right two described in erection simultaneously, then in the middle part of the movable girder steel risen, overhead trolley track is installed, complete a support work circulation of advance support system.
The invention has the beneficial effects as follows:
Single track handling tail of the present invention becomes first formula advance support system, carry out in the scope of lame advanced supporting at whole employing unit supports formula hydraulic support, the tail adopting tailstock to become first frame becomes first formula and moves shut die formula, achieve coal mine roadway without repeatedly supporting advance support, thoroughly avoid the destruction of hydraulic support to back and bolting with wire mesh system; The movable girder steel set up between the unit supports formula hydraulic support top beam of both sides, tunnel can overhead monorail slip crane walking track, movable girder steel also achieves being uniformly distributed of unit supports formula hydraulic prop ability, jointly can go better to safeguard back with hydraulic support, movable girder steel also improves the stability in the unit supports formula hydraulic support lifting process of the left and right sides, tunnel simultaneously; Adopt single track slip crane trolley units hydraulic chock-shield support in the middle part of tunnel, thoroughly avoid the adverse effect that Floor Heave in Roadway distortion produces, the single track slip crane speed of travel is fast, compact conformation, up-and-down strong adaptability moved towards to tunnel; Unit supports formula hydraulic support enabling capabilities is strong, compact conformation, height magnification are large, to different section size tunnel strong adaptability; Single track handling tail becomes first formula advance support system can meet the requirement of modernization high yield and high efficiency mine to advance support completely.
