Abstract
A coal mine tunnel gangue transshipment and supporting all-in-one machine is construction equipment of coal mine cannon-digging tunnels, and mainly optimizes gangue loading and supporting processes. Rocking loading, transportation and gangue discharging are working procedures which take longest time in digging work in tunnel digging construction. To achieve quick and efficient digging of the tunnels, the problems that gangue stacking, delayed gangue discharging and difficult temporary supporting and fixation need to be solved. To solve the preceding problems, the utility model provides the coal mine tunnel gangue transshipment and supporting all-in-one machine which can timely transship gangues and meanwhile provides a platform for supporting operation by means of explosion. The coal mine tunnel gangue transshipment and supporting all-in-one machine is designed on the basis that explosion operation characteristics in the digging of a coal mine are fully analyzed, and is formed by combination and machining of aluminum bronze sheets with good heat dissipation performance and hydraulic oil cylinders and the like. The machine is provided with power by means of a hydraulic system, and is stable in power output and capable of being used in relatively complicated geological environments.
Description
Technical field
The present invention relates to the construction equipment of coal mine roadway driving, relate in particular to the dress cash in big gun pick tunnel and the carrying out of roadway support operation.
Background technology
Reach its maturity in the mining mechanization technology, and driving operation relative complex, mechanization degree be still under the lower objective circumstances, heading driver's labour intensity is large, efficiency is low, income level is low, danger coefficient is high.Finally, cause tunneling recruitment anxiety, inefficiency, mine faster than driving, take over nervous passive situation.Tunnelling is a multiple operation alternation procedure, mainly is comprised of broken rock, shipment and supporting three large operations.At present, broken rock mode generally is divided into hand digging, explosion, machinery etc.; Shipment mainly is to use rake cash machine, fully-mechanized digging machine and forklift etc. to cooperate many equipment mixing discharge refuses such as mine car, shuttle car and chain mat machine (belt); Supporting mainly is divided into temporary lining and permanent support, and the concrete manifestation form is frame canopy, anchor pole and bolt-spary supports etc.Muck, transportation, discharge refuse are that the amount of labour is maximum in the headwork in the tunnelling construction, account for the operation of circulation timei the longest (reaching 35% ~ 50%).The driving muck transports the optimization of comprehensive discharge refuse ability, and speedy drivage is of great significance.The science and technology fast development makes all kinds of Novel tunnel heading equipments, technology continue to bring out, and promoted steadily driving speed, yet existing heading equipment adaptive capacity is poor, performance is short of, fault rate is high, maintenance cost is high, and the automation application degree is limited, coal mine roadway is produced driving speed formed harmful effect.Realize the rapidly and efficiently driving in tunnel, show that very outstanding to be exactly that the spoil of driving face is piled up serious, discharge refuse and test big gun work and can not in time carry out; Temporary lining is comparatively heavy, loaded down with trivial details, fixing difficulty, use inconvenient, and the tunnel clear height surpass 2.2 meters after the supporting operation when carrying out personnel must stand on ladder or the false platform comparatively difficulty of construction.Discharge refuse can not parallelly carry out with the supporting operation, large section roadway supporting difficulty, the construction of the safe and efficient mine that seriously restricting the renewal of coal mine excavation equipment and development, is seriously restricting.
Summary of the invention
In order effectively to solve the problem in the above-mentioned manufacturing process, the invention provides a kind of blasting energy that can utilize in time with gangue reprint, can provide platform---" coal mine roadway gangue reprint, support integrated machine " for the supporting operation again simultaneously.The present invention only has a narrow and small scope of freedom in abundant analysis driving face in coal mine jewel hole, elementary errors, bench blasting method and excavation bursting work, the clipping of four sides rock mass is very strong, disposable explosive quantity is subject to larger restriction, the impact of the factors such as step Free Face Conditions, utilize short-delay blasting in the collision shattering process, kinetic energy in the coal (rock) reduces, cause throwing apart from reducing, form the quick-fried heap of relatively concentrating, and quick-fried heap section profile line has, and these characteristics of Weibull distribution function curvilinear characteristic design.The aluminium bronze plate of " coal mine roadway gangue reprint, support integrated machine " employing heat dispersion excellence, hydraulic jack etc. process, and mainly are comprised of parts such as running part, support bearing section, firm section, assisted loading section, reprinting limiting section, front-probe support section, hydraulic systems.The present invention can realize fast quick-mounting cash, the immediate support of colliery digging laneway, reduces to greatest extent the exposed time of explosion profile, increases work efficiency.The machine total system adopts hydraulic system that power is provided, and the power stable output is applicable to the geological environment of relative complex.Succeeding in developing of this equipment will be reduced the driving recruitment, be improved drivage efficiency, for excavation operation provides the operated from a distance platform, has comparatively outstanding Social benefit and economic benefit.

The specific embodiment
In the coal mine roadway tunneling process, use jumbo or multi-section drilling tool; carry out perforating in strict accordance with step shot hole blasting chart; after the powder charge " coal mine roadway gangue reprint, support integrated machine " opened to meeting head on and carrying out firmly (needing in case of necessity carry out necessary protection to firm monomer; such as Fig. 2); then launch to reprint limiting section, carry out bursting work; upper caving shield receipts reprinting limiting section carries out permanent support behind preliminary safety verification; then receive firm section and transport unloaded operation (such as Fig. 3), roadway head carries out perforating, prepares next circulation simultaneously.Fabrication design for example: coal mine roadway gangue reprint, support integrated machine " can carry out according to objective condition such as drift section, the gradients customized separately; now calculate its result of use and equipment adaptive capacity (this specification equipment conveying is convenient, and can not disintegrate enters the driving face of most of mine) with 3 meters of length, wide 1.5 meters specification schools.One, " coal mine roadway gangue reprint, support integrated machine " self weight:
