Description
Technical field
The present invention relates to the packing job of down-hole, mine, particularly a kind of mine underground filling system to the goaf.
Background technology
At present, in the mining operation, the exploitation of subterranean resource constantly destroys underground original material and forms form, underground water flow field, stress of primary rock field isoequilibrium, and forms underground goaf.When the process of mining operations did not exceed the control range of setting, its operation process was safe; Out of control when the process of mining operations, when exceeding the control range of setting, will take place to pour in down-hole, mine safety accident such as pressure activity on a large scale such as roof fall, gushing water, surface subsidence, mud-rock flow or surface water.The generation of these security incidents all has close getting in touch with the existence in goaf.If in mining operations, high-quality filling is carried out in the goaf, above-mentioned security incident can obtain effective prevention and control, and therefore, the casting resin bashing along with the propelling of stope, is progressively used in most of mines in the ore extraction process.
Situation such as desired loss late can adopt following two kinds of filling method bashings when the mine generated angle, ore adjoining rock stability situation and mining according to ore body metamorphosis complexity, orebody thickness, ore body.One, adopt mine car or other mechanical transport to do the dry filling method of casting resin (like abandoned mine, sandstone, concrete etc.) bashing; Two, utilization waterpower is selected the hydraulic fill method of bashings such as factory's tailings, smeltery's slag, rubble along line transportation.
When adopting the ore dressing plant tailings that underground goaf is carried out filling at present; Usually adopt the hydraulic fill method; Volumetric concentration is delivered directly to the filling area for the 20-60% mine tailing; Method is simple, efficient is high, but will cause following adverse effect: 1, because the tailings granularity is very little, the mine tailing that charges into the goaf needs the long time deposition and witheredly just can bear certain pressure; And follow-up ore need can just can be proceeded exploitation under the condition of bearing certain pressure in the filling area, has therefore hindered the exploitation of follow-up ore.2, a large amount of tiny tailings flow into shaft sump with current in the tailing-filled process, cause the shaft sump alluvial, destroy mine drainage underground system.3, the water in a large amount of mine tailings flows into shaft sump with mine tailing, has strengthened the drainage underground amount, consumes a large amount of electric power.
Adopt dry filling method can avoid above-mentioned shortcoming, do the casting resin bashing but present dry filling method generally adopts mine car or other machinery to carry from ground, compare with the hydraulic fill method, conevying efficiency is lower.
Summary of the invention
The object of the present invention is to provide a kind of mine underground filling system that utilizes the mine tailing slurry to carry direct filling through strength through the dehydration back.
This mine provided by the invention underground filling system comprises ore pulp conveyance conduit, filter, feeding warehouse, rotary feeder, ejector, blower fan, filling pipeline.Filter is connected in the port of export of ore pulp conveyance conduit, and pulp dewatering is produced dried tailings, and feeding warehouse is positioned at the port of export below of said filter, is used to store the dried tailings after said filter dewaters; The port of export of feeding warehouse connects rotary feeder, and the port of export of rotary feeder connects ejector; Rotary feeder flows to said ejector continuously equably with the dried tailings in the feeding warehouse; Said ejector has charging aperture, air intake, three interfaces that communicate of discharging opening; Wherein charging aperture is connected with the port of export of said rotary feeder; Air intake is connected with said blower fan; Discharging opening is connected with said filling pipeline, and the gas of importing from blower fan is delivered to filling area with the dried tailings the ejector cavity through filling pipeline as power.
Said feeding warehouse comprises cylinder, and the lower end of cylinder connects the circular cone bucket of convergent.
Said rotary feeder comprises and the vertically arranged columniform housing of said feeding warehouse; The longitudinal center line coplane of its longitudinal center line and said feeding warehouse; There are the dried tailings import that is communicated with said circular cone bucket, the dried tailings outlet that the lower end has to be communicated with said ejector in the upper end, periphery middle part of housing; Dried tailings import is the horn mouth of convergent, and dried tailings outlet is straight nozzle; Rotatable impeller is arranged in the housing, and the central axis two ends of impeller are fixed on the housing, and the longitudinal center line of central axis overlaps with the longitudinal center line of housing.
Said ejector comprises spray chamber, and said charging aperture, air intake, discharging opening lay respectively at upper end, left end and the right-hand member of spray chamber; There is nozzle at air intake place in the spray chamber, and charging aperture is positioned at the back upper place of air intake, with the angle of air intake be acute angle, the end of nozzle is positioned at the bottom of charging aperture, discharging opening and air intake, nozzle are coaxial to center line, are the horn mouth of flaring.
Between said rotary feeder and said feeding warehouse, the ejector, be connected through flange respectively between said ejector and said blower fan, the filling pipeline.
The present invention utilizes filter that moisture mine tailing slurry dehydration is generated dried tailings earlier; Dried tailings utilizes the gravity decline of self to impact rotary feeder after feeding warehouse stores; Make the rotary feeder uniform rotation give the ejector feed; Blower fan air-supply simultaneously provide filling power blow dried tailings in the ejector through filling pipeline to the filling area, can continually carry out filling operation.The whole system configuration is simple, except conventional equipment filter and blower fan, no longer needs other external equipment, has low cost, high efficiency advantage.Overcome prior art and utilized the water conservancy filling to need a large amount of electric power to drain the defective the waiting period of the needs after mine water that the mine tailing slurry brings and the filling, also overcome the prior art dry stowing simultaneously and utilized mine car or other machinery to carry dried casting resin to come the defective of bashing inefficiency from ground.
