2 times to 5 times of the 11 right end diameter of a diameter of high-pressure hose of 11 left end of pipe.
A kind of coal mine gob totipotency paste body filling method, the coal mine gob totipotency paste body filling method use
Above-mentioned coal mine gob totipotency Paste-filling System, which includes following step
Suddenly：
Step 1 blocks the lower outlet of the offset to be filled 13 in filling operation face 12 tightly using plank 14, makes high-pressure hose
11 other end is corresponding with the upper outlet 10 of offset 13 to be filled, and make the spoil supply arrangement goes out spoil position (i.e. described
The discharge end of three spoil feed belts) it is corresponding with the upper outlet 10 of offset 13 to be filled, open the pulping equipment and spoil supply
The mixture of the slurry and spoil is perfused into offset 13 to be filled for equipment, until the mixture fills solid top plate.Tool
Body, the mixed slurry in slurry can 5 forms stable flow using the power that difference in height generates, and flows automatically after high-pressure hose 11
The upper outlet 10 in the filling operation face of being transported to 12 carries out gravity flow of going down the hill by the natural grade of offset 13 to be filled；Meanwhile spoil is slow
First spoil feed belt 18 of the spoil powder underground rushed in storehouse 17 is transported to district dip 9；By underground bastard coal separator
16 spoils generated are temporarily stored in spoil storage warehouse 15, and district dip 9 is transported to the 4th spoil feed belt 22；It is above-mentioned come artesian well
Upper, underground spoil is transported to and fills after the DR tape conveyer (i.e. the second spoil feed belt 21) of district dip converges
The upper outlet 10 for filling out working face 12 by the natural grade of offset 13 to be filled slip certainly downwards；Mixed slurry and spoil are one
It rises in rolling and is sufficiently mixed, form lotion in offset 13 to be filled, and gradually solid top plate, completion entirely wait filling branch from down to up
The filling in lane 13.
Step 2 makes the other end (such as right end of figure mesohigh hose 11) of high-pressure hose 11 outward next wait filling
Offset 13 moves, and so that the next offset 13 to be filled of spoil position outward that goes out of the spoil supply arrangement is moved, repeats step
1, until completion needs to be filled the filling of offset 13.I.e. as shown in Figure 1, from right to left one by one fill offset 13 to be filled,
Until completion needs to be filled the filling of offset 13.
By above-mentioned introduction it is found that the beneficial effects of the invention are as follows：
1, the requirement for meeting mine vertical transfer and underground long distance delivery spoil, in conjunction with high-water material mobility and glue
Knot property is good, and slurries are sufficiently mixed in being rolled together with spoil, realizes and flows automatically with potential energy, while eliminating agitating device and defeated
Device, entire stowing operation is sent not to need extra consumption power, to realize that the continuity and high efficiency of filling, filling cost are big
It is big to reduce；
2, because adding a certain amount of cement, there is long-term stability and stronger caking property and shear strength, completely
It can realize the molding requirement of charges；The lotion cement with initial flow rate is formed after mixing, realizes gravity flow filling knot
Real top plate, filling effect is good, and intensity is high, and effective controlroof destroys and ground settlement；
3, it since filling velocity is fast, realizes filling velocity and is more than drawing speed, solve the problems, such as that filling restricts exploitation,
It puies forward effect for the further exploitation of working face and creates space；
4, placement method of the present invention solves the problems, such as well on coal face's spoil, and solves at the spoil of ground coal washery
The problem of reason, also solves the process problem of fly ash in electric power plant, improves mining area periphery ecological environment.
The above, only specific embodiments of the present invention, the range that cannot be implemented with its restriction invention, so it is equivalent
The displacement of component, or according to equivalent variations made by scope of patent protection of the present invention and modification, should all still fall within what this patent was covered
Scope.In addition, between technical characteristic and technical characteristic in the present invention, between technical characteristic and technical solution, technical solution with
Use can be freely combined between technical solution.
