In the receiving hopper 23 for filling pump 1.Fill pump 1 along steel can compile pipe 3, straight tube seat 4,90 ° of wear-resistant bend 5, cloth tubes 13 by slurry
Goaf is pumped into, under the collective effect of the output of filling pump constant pressure and cyclone 18, slurry is entered with spray regime to be adopted
Dead zone.Accelerator pump 28 is arranged in tailentry, and accelerator is passed through the pump of accelerator delivery hose 29 by accelerator pump 28
Deliver in cyclone 18, under the compressed air effect of the rotation in cyclone 18, accelerator can be sufficiently mixed with slurry.In rapid hardening
Under agent, gases at high pressure and higher outlet pressure collective effect, slurry can be close to the obturation in goaf, in 10 minutes
Final set, possesses certain bearing capacity.
Steel tank chain 6 is wrapped in control cable of cloth tube 13, compressed-air hose 25 and correlation etc. in draft arm 14
Drive under, intelligent automatic moving type dolly 7 can be followed to move left and right, the mechanical arm 15 that intelligent dolly 7 is carried can drive cloth
Expects pipe outlet is moved up and down and circle swing by a small margin in goaf, tunneling boring in so achievable working face rear goaf
Closely knit injection filling, can be achieved to connect top in course of injection.
Intelligent automatic moving type dolly 7 possesses the navigation of sensor rail and ultrasonic radar automatic obstacle avoiding function, is equipped with simultaneously
Industrial rocking bar handheld device, it is autonomous when realizing normal packing job to move back and forth and manual guidance function in particular cases；
On the other hand, the mechanical arm that intelligent dolly is carried can drive cloth tube outlet to move up and down and circle swing by a small margin, such as
This can realize the closely knit injection filling of tunneling boring in the goaf of working face rear, can be achieved to connect top in course of injection, carry significantly
High pack effectiveness.
The rear lower for filling support 1 sets bottom bracket 9, middle barrier 11 and rear portion baffle plate 12 in bottom bracket 9
Between region in be provided with 2 road magnetic stripes.When system is normally run, its own outfit of the utilization of intelligent automatic moving type dolly 7
Sensor can be moved independent navigation between twice magnetic stripe 16, be provided simultaneously with ultrasonic radar automatic obstacle avoiding function；System occurs
Problem, it is impossible to during independent navigation, using industrial rocking bar handheld device, realizes manual guidance.
Illustrate the method for operation of the present invention by taking 21104 fully-mechanized mining workings in certain colliery as an example below：
The colliery annual production is 13.0Mt/a, and 21104 fully-mechanized mining working annual productions are 5.0Mt/a, mine design year work
At 330 days day, working face mining height 2.75m, working face total length 320m, support moving step pitch are 0.8m, using " four or six " duty, work
Make the daily coal-winning machine feed number in face for 18 knives, production class's time is 6h, then working face takes 60min per knife；The ore deposit is needed every year
It is 2.0Mt/a to want filling waste rock amount, and design filling pump actual fed slurry ability is about 360m3/ h, design goaf filling area
Segment length is 120m, therefore tunneling boring injection filling takes and is in the range of 120m：
120 × 2.75 × 0.8/360=0.74h=44.4min
When system is normally run, the translational speed of intelligent automatic moving type dolly 7 is 1m/s.
(1) when the coal cutting direction of coal-winning machine 24 is from tailentry to headentry
Gangue, flyash, cement and water are mixed to the slurry of better quality concentration in proportion first, and are transported to
Fill in pump receiving hopper 22.After coal-winning machine 30 starts, start lasting coal mining, when first group of tailentry side filling support
1 moves after frame, and filling space occurs in support rear.Now, electric gate valve 24 is opened, compressed air is entered by compressed-air hose 25
Enter cyclone 18；Start accelerator pump 28, accelerator is pumped in cyclone 18 by accelerator delivery hose 29；Restart
Pump 2 is filled, slurry compiles pipe 3, straight tube seat 4,90 ° of wear-resistant bends 5, cloth tubes 13 in the form of injection into goaf progress along steel
Filling；In stowing operation, mechanical arm 15 drives cloth tube 13 to move up and down and circle swing by a small margin, in favor of to goaf
Carry out full mining height filling；After being filled in the filling space at first group of rear of filling support 1, intelligent automatic moving type dolly 7 is to work
Make face transportation roadway direction to move, it is same that the draft arm 14 on intelligent automatic moving type dolly 7 drives steel tank chain 6 to follow its mobile phase closely
Distance, starts to fill next filling space.With the continuous operation of coal mining activity, coal-winning machine 30 is constantly to working face
Transportation roadway direction is moved, and constantly carries out packing job during this, is now mined and filling parallel operations, until filling section
Finished by all fillings, intelligent automatic moving type dolly 7 drives steel tank chain 6 to return to first group of tailentry side filling branch
At frame 1, filling system operation suspension.
During this, the filling section tunneling boring injection filling in the range of 120m is taken as 44.4min, packing job completion
Afterwards, intelligent automatic moving type dolly 7 returns and 2min is taken at first support of return airway, and coal-winning machine 30 runs the knife time and is
60min ＞ 46.4min.
(2) when coal-winning machine coal cutting direction is from headentry to tailentry
Coal-winning machine is persistently mined, when within operation to goaf filling section, although filling support 1 rear is filled
Space, but influenceed due to being moved frame by filling support 1, intelligent automatic moving type dolly 7 cannot be introduced into the middle barrier 11 of filling support 1
In Operational Zone between rear portion baffle plate 12, therefore packing job needs to fall behind one step pitch of coal mining activity.That is, coal-winning machine 30 is cut
When coal direction is from headentry to tailentry, without packing job, now intelligent automatic moving type dolly 7 is always
Positioned at first group of the tailentry side rear of filling support 1.When coal-winning machine 30 is transported from tailentry to working face again
During defeated lane coal cutting, mine and filling parallel operations again, now need the filling space of two step pitches of primary filling.
Now, filling system needs the space of two step pitches of primary filling, time-consuming 88.8min, after the completion of packing job, intelligence
Automatic moving type dolly 7 can be changed to return at first group of filling support 1 of return airway, 2min is taken, and coal-winning machine 30 is run to away from work again
Time-consuming 99min ＞ 90.8min are needed when making at the 120m of face termination.
(3) year waste filling amount
Consider the influence of the factors such as roof weighting, packed height takes 2.6m when calculating charging quantity, and the annual spoil of packing job fills
The amount of filling out is：
330 × 18 × 0.8 × 2.6 × 120=4492.8m3/d
That is, it is 2.593Mt/a that spoil and fine coal ash quantity can be handled every year, meets year filling waste rock 2.0Mt requirement, and
21104 working face normal productive capacities reach designed productive capacity 5.0Mt/a.
To sum up, no matter which kind of coal mining direction, when system is normally run, packing job does not influence coal mining activity, does not also influence
Mine annual production.
