Abstract
The invention discloses an underground backfilling and transporting method for ground gangue of a coal mine. The method comprises the following steps of: arranging a gangue crusher and a belt conveyer on the ground, constructing a vertical gangue conveying hole of which the diameter is more than 0.5 meter from the ground to an underground constructed overhauling roadway, establishing a surge bin on one side of the overhauling roadway, drilling a gangue slipway with the diameter of 1 meter between the surge bin and the conventional gangue storage bin which is a gangue bin or a coal bin, and arranging an upper pipeline in the gangue slipway; and crushing the gangue on the ground, then loading the gangue into the vertical gangue conveying hole by using the belt conveyer, allowing the gangue to fall to the surge bin due to self weight and automatically fall to the gangue bin for storage through the gangue slipway, and transporting and backfilling a certain quantity of gangue to a goaf. The method is not affected by interactive interference of main shaft and secondary shaft hoisting systems, facilitates transportation by using self weight of the gangue, and is low in treatment cost.
Description
Technical field
The present invention relates to the coal mine waste rock backfill technology.The cash backfill of washing that is specially adapted to the coal separation plant, colliery is handled.
Background technology
In the exploitation in colliery; The inevitable a large amount of spoil of association, along with the raising year by year of pit mining intensity, the output of spoil is increasing; The spoil of opening up stone head except that operating mine can directly directly be backfilling into the goaf in the down-hole; Spoil between mine construction stage, the spoil of operating mine coal separation plant all is put in ground, and pile up like a mountain.Existing mine spoil is handled has following several kinds of processing modes:
1. filling subsidence area: the surface subsidence district after mine is a kind of important mode of reclaiming with waste filling.Utilize the colliery cash as the subsidence area filler, can consume spoil in large quantities, solve the problem of reclaiming on the ground that subsides.But, containing a large amount of S, Mg, Na, K, Ca, Si, Fe, Al plasma panel in the coal mine waste rock, thereby there are serious pollution in environment and underground water and atmosphere, this kind method has greater environmental impacts.
2. generating: the discarded spoil of discharging in the coal mining process contains a certain amount of organic matter mostly, can utilize gangue in fluidized bed furnace, to burn and heat or generating, and the lime-ash after the burning can be used to produce constructional materialss such as cement.This kind method is had relatively high expectations to the calorific value of gangue, under the particular case, also must join colm and cooperate burning, and after the gangue burning, and emission gases processing cost up to standard is higher, and economic worth is not high, the applicable elements restriction.
3. brickmaking: the primary spoil of mine can and can utilize wherein contained organic spontaneous combustion, thereby economize in raw materials coal in order to batching brickmaking, and this method investment is little, and method is simple, and is widely-used.But in the brickmaking process, the part hazardous substances in the gangue is still residual, and the mankind are had potential health threat.And the spoil amount of brickmaking digestion is limited, does not possess the condition of extensive processing.
4. without any processing, directly be deposited in ground: this processing method land occupation, atmosphere pollution and water body, and destroy surface vegetation and view, have endless trouble.
5. waste filling: gangue is transported to the down-hole through mine car and belt, carries out the stope filling.This method meets the green exploitation policy of country, but the link of spoil transportation is many, and the equipment of input is many, can not realize continuous processing, and the cost that spoil is handled is higher.
Therefore, existing spoil treatment technology can not satisfy the raising of pit mining intensity far away, how to realize high strength, low cost, large-scale spoil processing, is the another new problem of current coal mining technical development.
Summary of the invention
The objective of the invention is to propose the backfill transportation resources of a kind of down-hole for solving the handling problem of spoil.
Technical scheme of the present invention is: spoil crushing engine and belt conveyer are set on ground; From ground to the maintenance tunnel of having constructed in the down-hole construction diameter greater than 0.5 meter vertical spoil material transport hole; One side is set up a surge bunker in the maintenance tunnel, utilizes existing waste bin or coal bunker as storage cash storehouse, between surge bunker and storage cash storehouse, gets through the slide cash road of 1 meter of a diameter; The slide cash is installed pipeline in the road, and slide angle of inclination, cash road is not less than 60 °; Spoil after pulverize on ground, is discharged in the vertical spoil material transport hole with belt conveyer, and the spoil deadweight falls to surge bunker, falls in the waste bin voluntarily through slide cash road to store again, and utilizes existing means of transportation to be backfilling into the goaf to a certain amount of back.
Be provided with wear-resistant sleeve in the above-mentioned spoil material transport hole;
The effective buffering of above-mentioned surge bunker highly is not less than 3 meters; Cut off with the brick wall of access path with thickness 50cm.
The present invention has the following advantages with present similar compared with techniques:
1. transportation system is independent, and the interactive interference that does not receive main shaft and auxiliary shaft to put forward system influences.
2. cost of transportation is low, utilizes spoil deadweight transportation, practices thrift processing cost.
3. system is simple, and corollary equipment is few, and early investment is few.
4. it is few to take personnel, and link is simple.
5. closed transportation, safe and reliable.
Description of drawings
Fig. 1 is the sketch map of the embodiment of the invention.
Among the figure: 1-crushing engine, 2-belt conveyer, 3-spoil material transport hole, 4-surge bunker, 5-access path, 6-slide cash road, 7-storage cash storehouse.
The specific embodiment
As shown in Figure 1, construction sequence of the present invention is following:
1. transportation system at first designes and constructes
Confirm the position in storage cash storehouse; Can utilize existing waste bin of mine or no coal bunker as storage cash storehouse 7; Access path 5 one sides of storage 7 tops, cash storehouse are widened, be divided into surge bunker 4, be not more than 60 degree inclination angles on the vertical direction of requirement storage cash storehouse 7 and surge bunker 4 with brick wall; Construct greater than the boring of 0.5 rice diameter at the vertical ground of surge bunker 4 simultaneously; Establish sleeve pipe in the boring as spoil material transport hole 3, to of the boring of storage cash storehouse 7 construction diameter, install pipeline in the boring as slipping cash road 6 greater than 1.0 meters at surge bunker 4; At ground configuration crushing engine 1 and belt conveyer 2 to spoil material transport hole.
2. the broken transportation of spoil
Wash cash and the digging gangue of coal separation plant, ground are discharged to spoil material transport hole 3 through belt conveyer 2 after crushing engine 1 is broken; The spoil freely falling body is transported to surge bunker 4; Utilize and pile up buffering, prevent to destroy bulkhead, piling height is not less than 3 meters; The spoil of piling up is passed to the waste filling work plane through transportation system's air transport then and carries out goaf filling through slipping cash road 6 from slipping in the storage cash storehouse 7.
