Abstract
The invention discloses a pumper and pipeline transportation type semicontinuous mining transportation technology for an open-pit mine. The pumper and pipeline transportation type semicontinuous mining transportation technology includes performing early-stage stripping and mining operation to form an open mine pit, arranging a pit bottom crushing station, a pit bottom stirring station and a pit bottom pump station at the bottom of the open mine pit, arranging a ground surface pump station, connected with the pit bottom pump station, at the outer side of end-slope ground surface boundary and pumping coal to a concentrating mill via a pipeline, and specifically includes firstly, arranging an excavator on a mining bench of a working slope for excavating operation; secondly, transporting mined coal to the pit bottom crushing station for crushing by a truck; thirdly, conveying crushed coal to the pit bottom stirring station, mixing the crushed coal with water to enable a mixture to have flowability and pumping the mixture to the ground surface pump station through the pit bottom pump station; finally, pumping the mixture, pumped to the ground, to the concentrating mill by the ground surface pump station via the pipeline. The pumper and pipeline transportation type semicontinuous mining transportation technology for the open-pit mine is applicable to small-medium-sized open-pit mines large in water inrush quantity and is capable of shortening coal transportation distance, saving coal transportation cost and reducing dust pollution.
Description
Technical field
The present invention relates to opencast mining technique, be especially a kind ofly applicable to the semicontinuous Mining Transport technique of middle-size and small-size, that water yield is large opencut pump truck pipeline transport.
Background technology
Have an opencast mining of an important branch as mineral industry, carry more and more important coal mining task, namely its essence peel off ore body overlying rock, directly obtains valuable mineral.Middle-size and small-size nearly horizontal opencut, coal production is less, and coal output is stablized.Tradition coal truck transport, needs to arrange transport channel at working pit edge, because light weight is comparatively large, needs to overcome the spent energy of truck deadweight and accounts for more than 50% of total power consumption.If coal adopts Belt transport, then end side transporter road need be set at end side broken step, not only impact end side transport, machine road move establish, technique for fixing is complicated, expend time in more, and cost of transportation is high, dust pollution is serious, and impact is produced.
Summary of the invention
Technical problem: the object of the invention is the weak point overcome in prior art, provides a kind of and reduces mine Coal Transport cost, minimizing dust pollution, improve the opencut pump truck pipeline transport semi-continuousmining technology of mine overall efficiency.
Technical scheme: the semicontinuous Mining Transport technique of opencut pipeline transport of the present invention, comprise stripping in early stage and adopt operation, form outdoor pit, hole end Crushing Station, hole end agitator and hole end pumping plant is put at described formation outdoor pit base fabric, arrange outside end side ground and cheat earth's surface pumping plant that end pumping plant is connected, deliver to ore dressing plant through tubing pump, pipeline transport semicontinuous Mining Transport processing step is as follows:
A. arrange that excavator carries out digging operation at working pit edge coal mining step;
B. with truck by coal mining charcoal be transported to hole the end Crushing Station carry out fragmentation;
C. the coal after fragmentation is delivered to hole end agitator to mix with water, makes mixed material have mobility, be pumped to earth's surface pumping plant by hole end pumping plant;
D. the material being pumped to earth's surface is delivered to ore dressing plant through tubing pump by earth's surface pumping plant.
Crushing Station at the bottom of described hole is automatic moving type crushing engine, Semi-fixed crushing station or fixed Crushing Station.
Beneficial effect: the semicontinuous Mining Transport technique of opencut pump truck pipeline transport of the present invention, is applicable to the surface mine that middle-size and small-size water yield is large.Coal mining system uses monobucket-automatic moving type crushing engine, agitator, pipeline Mining Transport technique, at working pit edge bottom coal mining charcoal that step is mined through automatic moving type crusher in crushing, be delivered to agitator again, with water in the mixing of setting ratio, by being delivered to pump (car), be pumped to earth's surface, be delivered in pipeline through pumping plant again, Cemented filling, to coal preparation plant, by by coal and water mixed transportation, achieves docking of exploitation and ore-dressing technique.Derivative on the basis of existing surface mine Mining Transport theory, when ensureing that mine normally produces, Coal Transport cost can be reduced, reducing institute's producing coal dirt in coal conveying.There is the advantages such as cost is low, green high-efficient, good economical benefit, Coal Transport distance can be reduced, save Coal Transport cost, reduce dust pollution.There is promotional value.
