Description
Technical field
The utility model relates to a kind of reusable Stope roof mechanical prop, is a kind of mechanical prop being applied to Stope roof supporting in underground metal mine Desending slicing mining filling method, belongs to mining machinery apparatus field.
Background technology
Narrow dipping vein for the underground metal mine of mining technique complicated condition is exploited, most employing has roof support with reinforced concrete to protect the Underhand cutting and filling method on top, i.e. slicing from top to bottom, on back production is complete after a layering, retain the pillar that it supports Stope roof, left in the goaf in roadway shape respectively, right flank country rock squeezes into anchor metal, at anchor pole overhanging end welded reinforcement, and finally form crisscross steel mesh reinforcement in goaf, next build one in entrance, goaf and stop up wall, goaf is made to form a confined space, then to the full concrete of goaf filling, be built into the roof support with reinforced concrete of next layering, and the ore of the next layering of back production under this top board.When the next layering of back production, often push ahead certain distance, all need vertically to support roof support with reinforced concrete at regular intervals near country rock place pillar in both sides, goaf, prevent from crushing, guarantee stoping operation safety.Adopt which type of pillar to support top board, not only safe and reliable but also economical and practical and non-environmental-pollution, one is worth the important technology problem of research beyond doubt.At present, in the metal mine Stope roof supporting adopting Underhand cutting and filling method, the support form of main employing wooden prop and shaped steel pillar, in the roof timbering of downhole coal mine coal-face, mainly contain the support forms such as wooden prop, elemental metals friction prop, hydraulic prop and hydraulic support, mechanical prop has indivedual application.Wooden prop is due to after stretching, and inconvenience is reclaimed and reclaimed dangerous, so wood consumption is large, cost is high, and wood source is comparatively limited, and during support, labour intensity is large; After the shaped steel pillar stretching made of channel-section steel etc., also inconvenience is reclaimed and is reclaimed dangerous, uneven due to stope sill and top board, need according to the height fixed-length blanking of concrete Support Position, Height Adjustment and install inconvenience, labour intensity is large, cost is high, also because the bottom surface of pillar contacts the ore of stope sill and the steel concrete of top board respectively with end face, friction factor is little, lateral stressed difference, the shock wave of stope explosion ore is easily shaken down, and security performance reduces; The application aspect of mechanical prop; a kind of mechanical prop with waste and old hydraulic prop part repacking once had indivedual application in coal mine roadway driving temporary lining and mining operations; it is that power drive worm and wormwheel rotates with electric coal drill; worm gear orders about screw mandrel lifting column again and reaches lifting and setting load; there are hydraulic cushion protective device, piston, oil cylinder, pressure meter, safety valve etc. and ensure that pillar is flexible, reach different operating height by the length changing long joining section.But because it adopts Worm and Worm Gear Driving, transmission efficiency is low and speed reducing ratio large, and worm gear wheel is slow, cause the rising or falling speed of lifting column comparatively slow, without anti-explosion shake design, be not suitable for being applied to metal mine stope.In addition, intend a kind of mechanical prop in addition in colliery application, it mainly comprises conveyor screw device, lifting controller and brake.Drive the double helix screw mandrel that rotation direction is contrary to rotate forward by manpower, order about two nuts screwed at screw mandrel two respectively and move up and down, the top board of stretching bank and base plate.Owing to driving stretching by manpower and loosening pillar, labour intensity is large, adopts brake, prevent screw mandrel from reversing under roof pressure, required braking moment is large, keeps the reliability requirement of braking high for a long time to brake, also fall to design without anti-explosion shake, be not suitable for applying at metal mine stope.Metal friction pier construction is simple, and lightweight, cost is low, recyclable with reuse, but its setting load is little and uneven, impact safety in production, hydraulic prop is the main supporting support apparatus of colliery high-grade common coal mining face, it has internal-injection type and external poured two kinds, be provided with the working cycle process that triple-use valve controls pillar thereon, internal-injection type hydraulic prop relies on the hydraulic oil loaded in oil cylinder in inner loop work, because its internal construction is complicated, setting load is little and uneven, cost of production is high, the shortcomings such as labour intensity is large, apply less, the pressure liquid that outside injection type hydraulic pillar relies on emulsion power pack to export carries out just support, during unloading, emulsion is made to leak in coal-face by the feather valve on triple-use valve, during repeated work, just support is carried out again with the pressure liquid of emulsion power pack, the support force of single-column of face roof is even, safety is high, labor strength is low, hydraulic support is a kind of hydraulic prop equipment of coal mine fully-mechanized mining working, it can not only support coal-face top board effectively, and can move forward along with the propelling of coal-face, it possesses ascending, descending, pushes away, moves four elemental motions, each action is the highly pressurised liquid utilizing emulsion power pack to provide, come by the hydraulic cylinder of hydraulic control system control difference in functionality, the fluid pressure line of every frame support is all in parallel with work plane main line, forms separately independently hydraulic system.The advantages such as it is large that hydraulic support has enabling capabilities, and supporting performance is good, and erection translational speed is fast and safe and reliable.Hydraulic support and outside injection type hydraulic pillar all need to set up emulsion power pack, and the composition of its hydraulic control system, pipe-line system, mechanical system is complicated, and investment is comparatively large, and maintenance requirement is high.The emulsion of outside injection type hydraulic pillar leaks in coal-face, also creates the pollution of working environment and mine water.
In sum, in the Stope roof supporting using downward stratified mining filling method at underground metal mine and the supporting of downhole coal mine face roof, although existing several suspension device or support apparatus, have its limitation, or can not reclaim and reuse, cost is high, support inconvenient, labour intensity is large, and rising or falling speed is slow, efficiency is low, poor safety performance; Or fall to design without anti-stope explosion shake; Or need to set up emulsion power pack, hydraulic control system and pipe-line system, composition is complicated, and investment is large, and maintenance requirement is high, also causes the pollution of working environment and mine water.For the roof timbering of underground metal mine stope, simple and practical, safe and reliable, environmental protection and the few support apparatus of material consumption also less, be necessary to develop further simple and practical and can reclaim with reuse and free of contamination mechanical prop to replace wooden prop or shaped steel pillar, to meet the needs of Mine Stope roof timbering.
