Description
Technical field
The utility model relates to a kind of coal mine fully-mechanized mining device for the coal dirt band and combines mining method.
Background technology
In recent years, along with the lasting rising of the national economic development to coal demand, many collieries under the premise that security is guaranteed, mine output has also obtained improving constantly, cause the development engineering amount of mine big, to produce cash many, anxiety has to a certain degree appearred in assistant conveyance, and a large amount of spoils enters that the washing of coal supply has brought white elephant in the coal.
The upper strata has all been taked to adopt in a lot of collieries of dirt band in the existing coal, leaves the exploitation method of layer behind, and coal resources have been caused huge waste.
Also has and two-layerly all exploit, but the traditional processing mode of downhole gangue is to be carried to the face of land by the down-hole stacking that this brings very big threat and harm to human ecological environment and condition, mainly show: appropriation of land; Contaminated environment; Harm humans safety.In addition, just at the hillock of spontaneous combustion, as run into the infiltration of rainwater, the back air that is heated sharply expands, and can set off an explosion, and causes security incident.
This problem is as can not get effective solution, continues the anxiety except meeting causes the exploiting field work plane, and mine service-life also will shorten greatly.This not only can cause the great wasting of resources to country, also will be to social concerns such as environmental protection.
As seen, the hillock that tradition ground discharge refuse mode produces to the pollution of environment with destroy seriously, the method that adopts downhole gangue directly to handle then can be turned bane into boon: eliminate the ground hillock, reduce and occupy the farmland, reduce the surface subsidence that atmosphere and environment pollution, elimination are caused because of coal mining.Simultaneously, the reasonable processing under the waste shaft also can be as the underground structure supporter, can reduce barrier pillar and save coal resources, can partly solve again or reduces surface settlement and the problem of subsiding.
Summary of the invention
For the lower floor's coal seam waste that solves dirt band coal seam in the existing coal and the phenomenon that spoil pollutes, the utility model provides a kind of a complete set of equipment for dirt band coal seam, down-hole separative production and separative delivery gangue refill method, it can take upper and lower two-layer coal seam and spoil layer respectively, improved the coefficient of mining in coal seam, avoided the phenomenon of waste, simultaneously, can be transported to upper and lower coal seam aboveground and middle spoil is transported to underground goaf, effectively avoid the pollution to environment.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
Dirt band coal seam, a kind of down-hole separative production and separative delivery gangue refill a complete set of equipment, the anterior drag conveyor that comprises carrying coal-winning machine exploitation junk, the unloading end of anterior drag conveyor is provided with crossheading with transporting outward elevating conveyor, equipment of conveyer, equipment of conveyer is provided with realizes that fortune and spoil are backhauled the reversing arrangement of direction switching on the coal, unloading place of respective transfer conveyor reversing arrangement spoil is provided with the far-end elevating conveyor, the unloading end of far-end elevating conveyor is provided with and backhauls conveyor, and the unloading end that backhauls conveyor is provided with and backhauls elevating conveyor, the unloading end that spoil backhauls elevating conveyor is provided with the gangue refill rear portion conveyer that is suspended on filling support rear portion.
Further, described reversing arrangement is the commutation door.
Further, described outward transport elevating conveyor is provided with the one-level crushing engine.
Further, described far-end elevating conveyor is provided with secondary breaker.
Further, described anterior drag conveyor, the outward transport elevating conveyor, travelling belt, far-end elevating conveyor, backhaul conveyor, the rear portion conveyer forms back-shaped transit route.
Operating principle of the present utility model and beneficial effect show:
The utility model is by arranging the twice passage, and realizes the change of both throughput directions by a body is set.
The coal mining transfer passage: anterior drag conveyor, the output of anterior drag conveyor are provided with outward transport elevating conveyor, travelling belt successively;
The spoil transfer passage: anterior drag conveyor, the output of anterior drag conveyor are provided with outward transport elevating conveyor, travelling belt, far-end elevating conveyor successively, backhaul conveyor, backhaul elevating conveyor and backfill rear portion conveyer.
By can realizing up and down coal seam and spoil being exploited respectively and changing corresponding direction with upper channel, with the colliery be transported to aboveground, spoil is transported to the goaf.
The utility model is not only applicable to " dirt band in the high seam coal " and mines, and the exploitation of two girdles that go for fully apart having a contest.
This shows that the utility model has been realized high-efficiency mining, alleviated the service hoisting of mine, and the spoil that the down-hole produces directly can be handled, eliminate spoil ground and pile up the harm that human survival and living environment are brought.
Handle spoil by present technique, can alleviate surface subsidence to greatest extent, improve the economic benefit of mine, the sustainable development in colliery is had great realistic meaning; Simultaneously, can also solve problems such as China's spoil down-hole treatment, alleviation mine service hoisting anxiety, start a new technological approaches, its scientific and engineering Research Significance is very great.
With the processing of mine spoil, exploitation " dirt band in the coal ", two-layer ultra-thin coal seam primary recovery when 0.5～2.0m, the coal mining general arrangement is included on the protection face of land in, realizes green exploitation and the sustainable development of colliery resource and environment;
In sum, new coal mechanized equipment share limited public affairs in Shandong are based on the actual conditions of " dirt band in the coal ", two-layer ultra-thin coal seam primary recovery when 0.5～2.0m, started the new situation of fully mechanized coal face bastard coal separative production and separative delivery gangue refill coal-mining technique, improved " dirt band in the coal " the rate of extraction, reduced the destruction of Coal Production to the face of land and ecological environment, reformed the coal mining technology, guided the direction of coal mining enterprise's realization " green ".
