Abstract
The invention relates to a expansion filling material belonging to the technical field of buildings, water bodies and subway mining. The high-water expansion filling material is characterized by being slurry containing fly ash, an expansive agent, a retardant, an accelerating agent, a curing agent and water. The solid-liquid ratio is 1:1.2 to 1.5, the proportion is 1.35, and the expansion rate is 10-30 percent. The invention solves the problems of active pressing top-filling and long-distance gravity feeding in medium and thick coal beds and has very important meaning to the improvement of the domestic mining biological environment and the increase of the resource recovery rate.
Description
Technical field
The invention belongs to (abbreviation " three times ") coal-mining technique field under buildings, water body, the railway, be specifically related to a kind of expansion filling material that in stowing method is mined, uses.
Background technology
There is the abundant in coal resource in China, and reserves are at the forefront in the world, and big or small coalfield is dispersed throughout all parts of the country.All there are the problem of pressing coal to some extent in buildings, water body and railway, super highway that One's name is legion is arranged above the coalfield, each mining area.For a long time, the China's coal-mine coal winning method mainly adopts village (cities and towns) resettlement, band exploitation and this several method of filling mining.
Wherein, according to compaction material and mode of movement, the filling in mine production technique mainly contains following several kinds:
1, dry filling: be dry filling materials such as the piece stone of gathering, sandstone, soil, industrial residue to be transported to manpower, gravity or mechanical means treat fill area, form compressible loose pack body.Shortcomings such as such filling labour intensity is big, operating cost is high, the stope filling time is long, production efficiency is low, and filling effect is undesirable.
2, hydraulic stowing: be mine tailing to be charged into worked-out section by waterpower.Its weak point is: the compaction material of hydraulic stowing lacks cohesive characteristic, can not form the obturator of firm self-support, and stope needs a large amount of dehydrations.
3, consolidated fill: generally adopt silicate cement or other gelling material to add in the low concentration of water sandfilling material, mass concentration 60%～68% had both improved strength of filling mass, was easy to again realize carrying.But this technology in use exist slip solidify slowly, emanate layering, intensity is low and phenomenon such as inhomogeneous; But also has down-hole when dehydration gelling material and fine-grained tailing is prone to run off; Down-hole waste water, thin dirt are dyed environment; Problems such as draining, spoil disposal expense are high, and the stope mining cycle is long, and production efficiency is low.
For the colliery filling, general used filling aggregate is mainly solid waste such as coal gangue, river sand, soil inferior, and fines is generally flyash, blast-furnace slag etc.Its not enough outstanding behaviours is 3 problems: 1) casting resin connects the top difficulty, and filling effect is poor.Because lotion or mobile poor like the lotion slip is difficult to guarantee that filling is even, especially slip solidifies back drying shrinkage about 30%, is difficult to reach the purpose of control subsidence.2) carry cost high.The colliery resource is unlike the such relative small range that concentrates on of metal ore body, and the scope that extends in the plane is very big usually, and casting resin need be grown distances, adopts the lotion or the paste-like backfill of pumping mode certainly will increase filling cost.3) the broken cost of coal gangue increases filling cost.
Summary of the invention
The present invention provides a kind of expansion filling material, and purpose is that the active of thick following coal seam goaf filling connects top and long distances problem in solving.
The present invention has specifically adopted following technical scheme:
A kind of expansion filling material, the slip of forming by flyash, swelling agent, delayer, accelerating chemicals, solidifying agent and water; Its proportioning raw materials is following:
Its solid-to-liquid ratio is 1: 1.2～1.5, and proportion is 1.35, and rate of expansion is 10～30%.
Said swelling agent is an aluminium powder; Said delayer is a terra alba; Said accelerating chemicals is an aluminum oxide clinker; Said solidifying agent is lime, cement or its any mixture.
The method for making of expansion filling material of the present invention comprises the steps:
1, coal ash pulp is prefabricated: according to flyash and water weight ratio 1: 1.2～1.5, under agitation mix subsequent use.
2, solidifying agent slurry preparation: carry out runoff according to swelling agent, delayer, accelerating chemicals, solidifying agent and water weight ratio 1: 1.2～1.5 and stir, the back that stirs is subsequent use.
3, slip preparation: coal ash pulp and solidifying agent are starched according to throughput ratio 15～25: 1 gets in the steel basin continuously, stirs and promptly processes filling slurry.
Advantage of the present invention is:
1, have swelling property: rate of expansion 10%～30%, the top tight filling worked-out section of initiatively exerting pressure is effectively controlled the face of land and is not had disturbance.
2, good fluidity: do not need mechanical external force, reach gravity flow.
3, initial set is 1.5～2 hours, solidifies 8 hours intensity and reaches 0.4MPa, and intensity reached 1MPa in 24 hours, and intensity surpassed 1.5MPa in 7 days.
