Description

A kind of device and method using pressure-air conveying lotion
Technical field
The present invention relates to a kind of device and methods using pressure-air conveying lotion, belong in filling in mine exploitation and fill Slurry pipe transportation technology field.
Background technique
" under three " (under building, under railway, under water body) pressure that current many mining areas can not be exploited facing to traditional technology Coal problem.In order to sufficiently produce these mine " under three " coal resources, prolongs length of service, need filling mining to liberate " three Under " pressure coal.Paste body filling refers to that spoil, flyash, inferior soil, urban solid garbage around coal mine etc. are processed into cream on ground Body, the method filled by pipeline to goaf.
Filling in mine slurry pipeline transport method mainly has two kinds of self-flowing pastefill and pump pressure conveying at present.Self-flowing pastefill is to filling times More demanding, the goaf biggish for some stowing gradients of line, in order to guarantee that slurry flows to goaf under the effect of gravity, Having to, which reduces concentration, is conveyed, but slurry isolation, goaf effluent cost can be brought to increase, pollution subsurface environment etc. one Series of problems;Pump pressure conveying, which refers to, carries out pressurized delivered to fill paste using paste body filling pump, is on the basis of pump concrete A kind of filling method above to grow up.Fill paste is using primary pumping, the mode that remote pipe transports.Work as work After making face sand off, also there are a large amount of fill pastes in pipeline.Lotion is stopped in pipeline for a long time and is made in order to prevent At plugging problem, usually taken after sand off pumping mortar mode, lotion in pipeline is pushed out using mortar. A large amount of wastes of paste filling material are not only caused in this way, also add the cost of mortar.After lotion discharge, it is also necessary to use water Mortar is excluded, the draining burden of underground is increased.
Underground filling material squeezes delivery method and device (Chinese patent CN96118020.X) by pacifying in filling pipeline Dress piston-type extrusion mechanism conveys filling slurry, after being filled using this method, and traditional self-flowing pastefill and is pumped defeated Send mode is the same can leave a large amount of fill pastes in pipeline, for the progress of next filling operation, it has to this part Lotion and pipeline are cleared up, and which not only adds filling costs, can also be polluted to subsurface environment.
Due to the presence of these problems, the popularization and application of paste body filling production technique in a wider context are limited, therefore, Need to find new filling pipeline delivery method.
