Description
Technical field
The utility model relates to mine ventilation technology, and particularly a kind of deep-well ore body U-shaped stall ventilation system, is particularly useful for pole big thick ore body underground mining.
Background technology
In China, the extremely thick ore body of increasing deep-well needs to exploit, in the recovery process of deep-well pole big thick ore body, panel ventilation effect is very important, in usual panel, various roadway engineering is intricate, cause wind path windage skewness, distinguished and admirable air quantity is chaotic, irrational roadway engineering is arranged also may cause Air escape branch, cause the generation of the ventilating problems such as the dirty wind in panel circulates, foul atmosphere is stagnated, effective wind rate is low further, the healthy and production safety of serious harm underground work personnel.The design of mine ventilation system has become one of technical barrier of restriction pole big thick ore body exploitation success or not.
At present, the mode usually adopting multistage blower fan series and parallel to install both at home and abroad realizes mine ventilation system air quantity equilibrium assignment.Comparatively early China, after 1985, also progressively applied at many large-scale mines, and achieved certain effect the time of development abroad and application Multi-stage station ventilation method.But run there being trackless diesel-engine equipment, in the recovery process of the deep-well pole big thick ore body that mechanization degree is high, on the haulage drift that blower fan machine station sometimes needs to be arranged on production panel or return aircourse, seriously like this hamper the current of trackless equipment and personnel, constrain mining production.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design, safe and reliable deep-well ore body U-shaped stall ventilation system, with multistage blower fan string, the mode be installed in parallel is compared, by reasonably planning that the roadway engineering in each production panel is arranged, the distinguished and admirable circuit of scientific design, make windage, blast is rule distribution in tunnel, panel, avoid a series of ventilating problem such as Air escape branch in production panel, reduce or avoid the setting at inner blower machine station, panel, thus the solution of energy-conserving and environment-protective more extremely thick orebody mining time the panel that faces to ventilate the problem of difficulty, distinguished and admirable air quantity in reasonable distribution stall, improve effective of wind amount rate in panel, ensure the healthy and production safety of underground work personnel.
The technical solution of the utility model is:
A kind of deep-well ore body U-shaped stall ventilation system, it is characterized in that: comprise multiple independent panel, many extracting drifts are provided with in each independent panel, the scraper communicated with extracting drift transports connection roadway, the intake that connection roadway one end is communicated with is transported with scraper, the return aircourse that the connection roadway other end is communicated with is transported with scraper, be positioned at the downcast of intake initiating terminal, the returnairshaft being positioned at return aircourse end and the air door possessing long-range remote control function being positioned at return aircourse and blower fan, described downcast, intake, scraper transport connection roadway, return aircourse and returnairshaft form a U-shaped ventilation circuit.
Above-mentioned deep-well ore body U-shaped stall ventilation system, the quantity of described scraper transport connection roadway is more than three, the air intake end of all scraper transport connection roadways is all communicated with intake, only have the air opening end of the first scraper transport connection roadway near ore removal work plane for serving Panel stoping work to be directly communicated with return aircourse, other are for adopting the scraper transport connection roadway of accurate headwork by the first scraper transport connection roadway and return aircourse indirect communication.
Above-mentioned deep-well ore body U-shaped stall ventilation system, the downcast between two adjacent independent panels and returnairshaft interval are arranged, two adjacent independent panels share a downcast or returnairshaft.
The beneficial effects of the utility model are: because between each independent panel, ventilation system is separate, be independent of each other, tunnel windage in panel, wind force distribution are steady, distinguished and admirable allocation of the amount of air is balanced, avoid the setting at inner blower machine station, panel, more energy-conserving and environment-protective solve extremely thick orebody mining time the panel that faces to ventilate difficulty, Air escape branch, dirty wind circulation, the difficult problem such as foul atmosphere is stagnated, effective wind rate is low.
Accompanying drawing explanation
Fig. 1 is layout plan of the present utility model;
In figure sequence number illustrate: 1 downcast, 2 returnairshafts, 3 intakes, 4 return aircoursies, 5 first scrapers transport connection roadways, 6 second scrapers transport connection roadways, 7 the 3rd scrapers transport connection roadways, 8 air doors, 9 fresh distinguished and admirable, 10 dirty wind are distinguished and admirable, 11 extracting drifts, 12 blower fans.
Detailed description of the invention
As shown in Figure 1, this deep-well ore body U-shaped stall ventilation system, comprise multiple independent panel, A is provided with in the present embodiment, B, C tri-independent panels, many extracting drifts 11 are provided with in each independent panel, the scraper communicated with extracting drift 11 transports connection roadway, the intake 3 that connection roadway one end is communicated with is transported with scraper, the return aircourse 4 that the connection roadway other end is communicated with is transported with scraper, be positioned at the downcast 1 of intake 3 initiating terminal, the returnairshaft 2 being positioned at return aircourse 4 end and the air door 8 being positioned at return aircourse 4 and blower fan 12, described downcast 1, intake 3, scraper transport connection roadway, return aircourse 4 and returnairshaft 2 form a U-shaped ventilation circuit.The quantity of described scraper transport connection roadway is more than three, adopting three in the present embodiment, being respectively the first scraper transport connection roadway 5 near ore removal work plane for serving Panel stoping work and the second scraper transport connection roadway 6, the 3rd scraper transport connection roadway 7 for adopting accurate headwork.The air intake end of all scraper transport connection roadways is all communicated with intake 3, the air opening end of the first scraper transport connection roadway 5 is directly communicated with return aircourse 4, second, third scraper transport connection roadway 6,7 transports connection roadway 5 and return aircourse 4 indirect communication by extracting drift 11 and the first scraper, and the distinguished and admirable vent line length through the first scraper transport connection roadway 5, second scraper transport connection roadway 6, the 3rd scraper transport connection roadway 7 is identical.Downcast 1 between two adjacent independent panels and returnairshaft 2 interval are arranged, two adjacent independent panels share a downcast 1 or returnairshaft 2, and the tunnel between each independent panel is not communicated with mutually, independently of one another.
The air door 8 arranged in return aircourse 4, blower fan 12 all possess long-range remote control function, when in a certain independent panel face need fresh distinguished and admirable time, open air door 8 and blower fan 12, fresh distinguished and admirable 9, from downcast 1, are delivered to stope in panel by intake 3, wash away each work plane along scraper transport connection roadway, form dirty wind, dirty wind 10 is pooled to the first scraper transport connection roadway 5 along each extracting drift 11, then along return aircourse 4, drains into earth's surface by returnairshaft 2.When not having work plane operation or exploitation to terminate in panel, when not needing to ventilate, closing air door 8 and blower fan 12 by Remote, other panel ventilation system is not at all affected.
