Abstract
A goaf treatment method based on filling raises with surface barren rock includes; during the post-mining thin bedrock and shallow-buried goaf treatment in a mine, utilizing a full face digging method to dig downwards at least three raises to be straight communicated with the goaf through a digging machine, and then filling the goaf with the surface barren rock in a freely-dropping mode. According to the goaf treatment method based on filling the raises with the surface barren rock, the goaf can be filled up with the barren rock as much as possible and the roof exposure of the goaf can be reduced or even eliminated, so that the stability of the goaf can be enhanced and the collapse possibility of the goaf can be reduced; and meanwhile, due to the fact that the goaf is filled up with the barren rock, the intensity of the disaster caused by the collapse of the goaf roof can be reduced significantly and the mining safety of the mine can be effectively enhanced, so that the goaf treatment can be achieved. The goaf treatment method based on filling the raises with the surface barren rock is high in practicality, easy to achieve and capable of saving the cost effectively.
Description
Technical field
The present invention relates to a kind ofly get the method that face of land barren rock is administered the goaf based on fill pass, be particularly useful for having thin basement rock, shallow embedding goaf and having the filling that causes the disaster possibility of collapsing to administer behind the mining.
Background technology
When behind mining, the goaf being carried out filling and administers at present, the main method that adopts is to set up filling system, namely in roadway, arrange pipeline, the interim pipeline that passes through carries the cement mortar of face of land making to the goaf correct position, cement mortar dehydration back gluing reaches the purpose of bashing, this method needs that the well lane engineering of long-time maintenance is huge, the plant equipment of casting resin complex manufacturing process, input is many, cost is high, the filling system operation easily breaks down, need the lot of manpower and material resources financial resources, improved the mining cost.Therefore according to physical condition filling method is carried out reasonably optimizing, propose to get the method that face of land barren rock is administered the goaf based on fill pass, be conducive to the raising of this type of mine economic profit.
Summary of the invention
The objective of the invention is to overcome the weak point of traditional filling process, the possibility that a kind of effective attenuating goaf more simple and practical, that input cost is lower collapses is provided or the disaster intensity that causes of collapsing get the method that face of land barren rock is administered the goaf based on fill pass.
A kind of method of getting barren rock improvement goaf, the face of land based on fill pass: when administering thin basement rock, shallow embedding goaf behind the mining, utilize rig to adopt the straight-through goaf of at least three courtyards of driving under the full-face drilling normal direction from the face of land, get barren rock then on the face of land and by the mode that freely puts off filling is carried out in the goaf.
Further, the vertical vertical straight-through goaf of the courtyard of described rig driving.
Described face of land barren rock must pass through break process, can directly freely put off to the goaf.
Use the present invention, can make barren rock be full of the goaf as far as possible, reduce even eliminate goaf top plate and hang dew, increase the stability in goaf, thereby reduce the possibility that collapses in the goaf, simultaneously since the goaf by waste fill, the disaster intensity that causes also can reduce significantly even goaf top plate collapses, and effectively improves the mining safety, play the purpose of administering the goaf, practicality height of the present invention is realized simply effectively saving cost.
Description of drawings
Fig. 1 is that courtyard is in the floor map of face of land arrangement;
Fig. 2 is the preceding schematic diagram of the filling at I-I section shown in Figure 1 place;
Fig. 3 is schematic diagram after the filling at I-I section shown in Figure 1 place.
Among the figure: 1-basement rock, 2-goaf, the 3-face of land, 4-courtyard, 5-goaf top plate, 6-face of land barren rock, barren rock after the 7-filling.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, the present invention gets the method that face of land barren rock is administered the goaf based on fill pass: when administering thin basement rock 1, shallow embedding goaf 2 behind the mining, utilize rig under the 3 employing full-face drilling normal direction of the face of land, to tunnel many courtyards 4 straight-through goafs 2, get barren rock 6 then on the face of land and by the mode that freely puts off filling is carried out in goaf 2; The courtyard 4 vertical vertical straight-through goafs 2 of rig driving are so that freely the putting off of face of land barren rock 6; Because the barren rock 7 that freely puts off by same courtyard 4 can't be full of goaf 2, for being full of goaf 2 as much as possible, must tunnel at least three courtyards 4 on the face of land downwards; Simultaneously, face of land barren rock 6 must be through break process, make it directly freely to put off to the goaf 2.
Like this, after getting face of land barren rock 6 and administer goafs 2 by fill pass 4, can effectively reduce even eliminate the outstanding dew of goaf top plate 5, increase the stability in goaf 2, thereby reduce the possibility that collapses in goaf 2, simultaneously, because barren rock 7 fillings that goaf 2 is freely put off, the disaster intensity that causes also can reduce significantly even goaf top plate 5 collapses, and effectively improves the mining safety, plays the purpose of administering goaf 2.
Claims (3)
1. get the method that face of land barren rock is administered the goaf based on fill pass for one kind, it is characterized in that: when administering thin basement rock, shallow embedding goaf behind the mining, utilize rig to adopt the straight-through goaf of at least three courtyards of driving under the full-face drilling normal direction from the face of land, get barren rock then on the face of land and by the mode that freely puts off filling is carried out in the goaf.
2. according to claim 1ly get the method that face of land barren rock is administered the goaf based on fill pass, it is characterized in that: the vertical vertical straight-through goaf of the courtyard of rig driving.
3. according to claim 1ly get the method that face of land barren rock is administered the goaf based on fill pass, it is characterized in that: face of land barren rock must pass through break process, could directly freely put off to the goaf.
