Description

Coal separates with spoil and with the technical equipment of gangue refill
Technical field
The present invention relates to a kind of coal and spoil just separated coal when the coal-winning machine coal cutting with spoil, and with the technical equipment of gangue refill to the goaf.
Background technology
Coal is a kind of main energy, in national economy, plays a part very important.The coal industry of China is that significant contribution has been made in the national economic development over 60 years.Coal accounts for respectively about 76% and 69% in China's primary energy production and consumption structure, has effectively supported the development of national economy with society.Coal provides 78% power generation energy resource; Secondly, coal is one of main industrial chemicals of China, and 70% industrial chemicals is provided; Once more, coal is the important substance of agricultural production and cities and towns people's lives, and 60% civilian commercial energy is to be provided by coal.In the energy of verifying, coal accounts for 94.3%.In 50 ~ 60 years of future; Development along with new and renewable sources of energy, water power and nuclear power; The consumption proportion of coal in primary energy can descend to some extent, cause after Japan's Fukushima in 2011 9.0 grades of violent earthquakes nuclear leakage, countries in the world are more prudent to nuclear energy uses.So coal will be the main energy sources of China.
China is first big coal country in the world, wherein has in 25% the coal seam to have dirt band, because spoil is clipped in the middle of the coal seam, traditional coal winning technology can only consequently have been sneaked into a large amount of spoils with coal and spoil extraction in the lump in the coal, cause ature of coal to descend significantly.Simultaneously a large amount of spoils cause ground by down-hole fortune and have also wasted lot of manpower and material resources.After a large amount of in addition spoils are treaded, not only strengthened and adopted absolutely empty, aggravated surface subsidence, and the spoil extraction hoards also on ground and will take a large amount of soils, the combustion of sulfur in the long spoil of resting period one produces a large amount of sulfur dioxide serious environment pollutions.
Summary of the invention
The present invention is directed to above weak point, provide a kind of coal to separate with spoil and with the technical equipment of gangue refill, this method and equipment can be realized separating of coal and spoil; And with the gangue refill goaf; Avoided coal and spoil mixed and felled and transported, practiced thrift cost, protected environment to aboveground.
For achieving the above object the following technological means of employing of the present invention:
A kind of coal separates with spoil and with the technology of gangue refill, it is characterized in that may further comprise the steps:
A, utilize the coal mining machine cut to load onto layer coal seam and utilize drag conveyor, elevating conveyor, conveyor coal to be transported to aboveground;
B, utilize in the middle of the coal mining machine cut dress spoil layer and utilize the drag conveyor antiport that spoil is delivered to the spoil that is laid on the drag conveyor other end and backhaul on the elevating conveyor, spoil backhauls elevating conveyor spoil is backhauled to the throwing cash drag conveyor of plate opening in the intermediate channel in goaf at hydraulic support rear portion;
C, sequential adjustment are thrown plate openings of sizes in the cash drag conveyor, and spoil is thrown into the goaf uniformly;
D, utilize the coal mining machine cut to load layer coal seam and utilize drag conveyor, elevating conveyor, conveyor coal to be transported to aboveground.
A kind of coal separates with spoil and with the outfit of gangue refill; Comprise coal-winning machine; But the below of coal-winning machine be provided with rotating, with the drag conveyor of coal-winning machine for the walking corollary equipment, the forward of said drag conveyor transportation end is supporting with it to be provided with elevating conveyor, reverse transportation holds the spoil that be provided with towards goaf supporting with it to backhaul the conveying unit.
Above-mentioned outfit, described spoil backhaul carry unit to comprise that spoil backhauls elevating conveyor and the intermediate channel that is mated in the throwing cash drag conveyor of plate opening.
Above-mentioned outfit, said throwing cash drag conveyor hangs on the hydraulic support rear portion; The plate openings of sizes is adjustable in the said throwing cash scratch board conveyor; Said throwing cash drag conveyor is provided with hydraulic jack; Described elevating conveyor is positioned at the haulage gate place; Spoil backhauls elevating conveyor and is positioned at the return airway place; Said drag conveyor is parallel with throwing cash drag conveyor.
For showing difference, disambiguation, special conveying equipment among the application is done following explanation:
" drag conveyor " but be meant the conveyer that can be used for carrying coal or spoil that cooperates the rotating running with coal-winning machine;
" elevating conveyor " is meant that the delivery end that is just changeing with drag conveyor is corresponding and with the coal elevating conveyor of transportation upwards;
" spoil backhauls elevating conveyor " be meant the delivery end with drag conveyor counter-rotating corresponding and with spoil to throwing the elevating conveyor that the cash drag conveyor transports;
" throw cash drag conveyor " is meant the conveyer that backhauls with spoil that elevating conveyor cooperates and spoil thrown to the goaf.
Operating principle of the present invention and beneficial effect show:
When adopting day-coal; The anterior drag conveyor forward running of work plane; The coal mining machine roller rotation is carried out coal cutting, is coaling to drag conveyor, and drag conveyor is discharged to coal on the elevating conveyor of haulage gate, and the belt conveyer through the transportation lane is transported to coal aboveground then.
After day-coal has been adopted, the spoil layer in the middle of arriving, because of the present invention the other end of drag conveyor just oppositely the transportation end set up the spoil of convey materials direction and backhauled elevating conveyor towards the goaf; Behind the intact coal seam, upper strata of coal mining machine cut; Change the throughput direction of drag conveyor, make the drag conveyor antiport, coal-winning machine exploitation spoil; Spoil falls into drag conveyor; The drag conveyor antiport is discharged to spoil and backhauls on the gangue reprint machine, backhauls the gangue reprint machine and spoil is discharged on the throwing cash drag conveyor that is suspended on the hydraulic support rear portion; The middle plate of every joint intermediate channel of rear portion drag conveyor all has the leakage cash mouth of adjustable openings size, and spoil is shed in the goaf through the leakage cash mouth of intermediate channel uniformly.Realization separates exploitation with coal with spoil, and has solved the gangue refill problem, has practiced thrift great amount of cost.
After middle dirt band has been adopted; The anterior drag conveyor forward running of work plane; Coal-winning machine is cut off a layer coal, and the coal mining machine roller rotation is carried out coal cutting, coaling to anterior drag conveyor, and anterior drag conveyor is discharged to coal on the elevating conveyor of haulage gate; Belt conveyer through the transportation lane is transported to coal aboveground then, finally accomplishes a circulation.
The conveyer of work plane transportation system and elevating conveyor reasonable Arrangement, floor space is little, and compact conformation is convenient to the current and maintenance of equipment of work plane operating personnel.
This shows that the present invention can solve the situation that the coal seam accompanies spoil under the situation of upwards not transporting spoil, can the coal seam be separated with spoil, and with the backfilling material of spoil as the goaf; Transport the power consumption of down-hole when having avoided spoil, and spoil is at aboveground occupation of land and pollution on the environment with coal.
