Description
Technical field
The invention belongs to coal mine drainage field, a specially a kind of lane is mostly used the discharge method of formula water in gob area.
Background technique
In coal mine, 14-2#Layer western two panel centralized return air system, track, belt lane, above covering 8-10 meters or so is 11-2#Layer 8927
~8937 face goafs, to prevent heterogeneous goaf from having carried out slip casting to goaf early period, goaf now adds up ponding 25.8 ten thousand
Cubic meter, covers 14 under-2#The driving of belt, track, air return lane is concentrated to form hidden trouble in western two panel of layer.It is applied using conventional
The drilling of work leting speeper discharges water by face, seriously affects developing linking, according to conventional leting speeper construction technology, tunnel is during driving
Drilled using working face leting speeper of meeting head on to construct in advance, stop pick if having water after inspecting hole probing and discharge water, after ponding emptying again into
Row driving, can not tunnel during discharging water and the period is long, slow effect.
Summary of the invention
It is an object of the invention to put water in gob area in order to solve the drilling of existing construction leting speeper by face and seriously affect
The problem of developing linking, provides a kind of discharge method of multi-purpose formula water in gob area in a lane.
The present invention the technical solution to solve the technical problem is that: an a kind of lane is mostly used the discharge method of formula water in gob area,
Characterized by comprising the following steps:
Centralized return air system lane is in tunneling process, when at driving to the crossheading lane position nearest apart from Overburden gob area minimum point,
Start the advance development crossheading lane that turns；
When crossheading lane is tunneled at the minimum point proximal most position of Overburden gob area, in the several drillings of roadway construction, drilling
Position and quantity according to the lowest point and water accumulating volume of Overburden gob area determine, the distal end of drilling extends to cover and adopt
Dead zone；
After drilled via, diversion pipe is installed additional in the borehole；
After all drilling constructions finish, water-proof sealing wall, crossheading are built by laying at crossheading lane and centralized return air system the lane entrance to a lane that has a common boundary
The bottom that lane and water-proof sealing wall have a common boundary is provided with discharge outlet, and protection grate, step are provided at the discharge outletIn water conservancy diversion
Pipe extends on the protection grate from discharge outlet from goaf, and centralized return air system lane and water-proof sealing wall intersection dig sedimentation basin, institute
It states discharge outlet and is connected to sedimentation basin；
Ponding in sedimentation basin is concentrated by suction pump to be discharged.
The beneficial effects of the present invention are: the discharge method that a lane is mostly used formula water in gob area through the invention can be real
Now driving, which discharges water, neglects neither, and does not stop to dig during can satisfy draining during draining, accelerates tunnelling, reduces artificial, equipment
Etc. investment, bring takes over nervous situation during reducing draining, while opening for drainage can also serve as tunnel crossheading at one stroke two
, ponding hidden danger in front of place system tunnelling is effectively solved, is on the one hand realized and is covered ponding by effectively and concentrate discharge, it is another
Aspect also achieves the preservation situation for finding out crossheading lane place working face in advance, for example coal seam is lower than minable thickness, then can shift to an earlier date
Panel design is modified, has accomplished the integrated planning of optimization panel and arrangement；Opening for drainage is opened up using gate road advantage, was both realized
Drift dewatering, and avoid tunnel footage unpayable；Construction waterproof fire dam and sedimentation basin during draining, by ponding effective drainage, together
When do not influence system tunnelling；After ponding drains, removes the closed gate road that restores and normally tunnel.
Detailed description of the invention
Fig. 1 is the tunnel work that an a kind of lane of the present invention is mostly used under the discharge method exploitation of formula water in gob area
Make face on-the-spot schematic.
In figure: 1- centralized return air system lane；The Overburden gob area 2-；3- crossheading lane；4- drilling；5- diversion pipe；6- water-proof sealing wall；
7- protects grate；8- sedimentation basin；9- overflow hole；10- peep hole.
Specific embodiment
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be to skill of the invention
Art scheme is described in detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than all real
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art without making creative work gained
The every other embodiment arrived belongs to the range that the present invention is protected.
Referring to attached drawing, the discharge method for being now mostly used formula water in gob area to an a kind of lane provided by the invention is illustrated.
An a kind of lane is mostly used the discharge method of formula water in gob area, which comprises the following steps:
Centralized return air system lane 1 is in tunneling process, at driving to 3 position of crossheading lane nearest apart from 2 minimum point of Overburden gob area
When, start the advance development crossheading lane 3 that turns；
When the driving of crossheading lane 3 is at 2 minimum point proximal most position of Overburden gob area, as shown in Figure 1, in roadway construction
It is several drilling 4, drill 4 position and quantity according to the lowest point and water accumulating volume of Overburden gob area 2 determine, drilling 4
Distal end extend to Overburden gob area 2；
It drills after 4 through-holes, installs diversion pipe 5 additional in drilling 4；
After all 4 constructions of drilling finish, water-proof sealing wall 6 is built by laying in crossheading lane 3 and 1 boundary entrance to a lane of centralized return air system lane,
The bottom that crossheading lane 3 and water-proof sealing wall 6 have a common boundary is provided with discharge outlet, and protection grate 7, step are provided at the discharge outletIn
Diversion pipe 5 extended on the protection grate 7 from discharge outlet from goaf, centralized return air system lane 1 is dug with 6 intersection of water-proof sealing wall
Sedimentation basin 8, the discharge outlet are connected to sedimentation basin 8；
Ponding in sedimentation basin 8 is concentrated by suction pump to be discharged.
Further, as a kind of specific embodiment party of the discharge method of the multi-purpose formula water in gob area in a lane of the present invention
Formula is installed with overflow hole 9 and peep hole 10 on the water-proof sealing wall 6.When water accumulating volume is too big, and discharge outlet discharge capacity is too small or
When grate 7 being protected to block, ponding overflow, ponding may cover water-proof sealing wall 6, and setting overflow hole 9 can effectively will be extra
Ponding is discharged by an other pipeline, flows into sedimentation basin 8；By stay set 10 staff of peep hole can be from centralized return air system lane
1 observes the drainage situation after water-proof sealing wall 6, very convenient.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be without departing from the purpose of the present invention
It makes a variety of changes.
