Abstract
The invention relates to a U-U-type ventilation method and system for coalfaces. The ventilation system mainly comprises the two U-type coalfaces which are arranged adjacently, and an isolation coal pillar is arranged between the two U-type coalfaces; one of two crossheading roadways of the first U-type coalface is used for air inlet, and the other crossheading roadway of the first U-type coalface is used for air return; one of two crossheading roadways of the second U-type coalface is used as an inlet air distribution way of the first coalface, the other crossheading roadway of the second U-type coalface is used a gas exhaust way of the first coalface, and the two U-type coalfaces are communicated through a transversal part to form the U-U-type ventilation system for the coalfaces. According to the U-U-type ventilation system for the coalfaces, due to the fact that the first coalface air distribution way, the second coalface and the gas exhaust way of the first coalface can be reused, substantially, the tunneling engineering quantity of the coalfaces is basically the same as that of a single-U-type ventilation system, however, the gas treatment effect of the U-U-type ventilation system can be achieved, and therefore the U-U-type ventilation system is particularly suitable for high-gas and outburst mines.
Description
Technical field
The invention belongs to coalmine ventilation field, specifically a kind of coal-face U-U type method of ventilation and ventilation system.
Background technology
The ventilation system of coal face is the important component part of mine ventilation system, and coal-face tunnel layout and ventilation system directly have influence on tunnelling engineering amount and the face gas regulation effect of full mine.Design adopts rational coal-face ventilation system not only can effectively reduce mine development end engineering quantity, and can obtain good gas control effect, prevent from or reduce Top Corner Gas on Coal Face transfiniting, significant to ensureing safety in production and the high-yield and high-efficiency of coal-face and full mine.
At present, in China's coal-mine, highly gassy mine, projecting mine adopt U+L type, U+I type, Y type, inclined to one side Y type, double-U-shaped ventilation system etc. more.In above coal-face ventilation system, U+L type, U+I type, inclined to one side Y type and each coal-face of double-U-shaped ventilation system all need to tunnel more than three gate road, and tunnelling and maintenance engineering amount are large, affect digging and are connected; And Y type and partially Y-shaped ventilating system all need to carry out gob side entry retaining, in the mine pressure larger more difficult enforcement of mine gob side entry retaining or maintenance, and gob side entry retaining expense is higher, restricted application.

After the first work plane knot is adopted, when back production the second work plane, recycling the first work plane air distribution lane, the second work plane and the first work plane Wa Pai lane.
The distinguished and admirable route of coal-face U-U type ventilation system is: a part is fresh distinguished and admirablely enters the first coal-face by the first work plane air intake lane, fresh distinguished and admirable main distinguished and admirablely flowed out by the first tailentry after work plane of washing away, separately there is part to leak out distinguished and admirable by work plane (being the mainly work plane return air upper corner) goaf of bleeding, dilute and carry after the high concentration gas of the first work plane goaf (be mainly the first work plane return air upper corner after goaf part), flowing into first work plane Wa Pai lane through first untight traversing of first work plane that lags behind; Another part is fresh distinguished and admirablely flows into the first work plane Wa Pai lane from first work plane air distribution lane the second work plane (cut eye), dilution the first work plane goaf contain leaking out of high concentration gas distinguished and admirable after, flow out work plane by the first work plane Wa Pai lane.
After the first work plane coal body knot is adopted, when back production the second work plane coal body, only need arrange again a U-shaped ventilation system of list right-hand the staying after establishing isolated coal pillar of the second work plane, form the second work plane air distribution lane and the second work plane Wa Pai lane, on isolated coal pillar, digging traverses with the second work plane and is communicated with, and reuse the first work plane air distribution lane, the second work plane (cutting eye) and the first work plane Wa Pai lane, the first work plane air distribution lane is adjusted into the second tailentry, the first work plane Wa Pai lane is adjusted into the second work plane air intake lane, can form the U-U type ventilation system of the second work plane, so circulation, until this wing coal-face complete extraction of exploiting field is complete.
Be suitable for the inventive method, a kind of U-U type ventilation method, system, the first coal-face and the second adjacent layout in coal-face left and right, between the first coal-face and the second coal-face, be provided with isolated coal pillar, on described isolated coal pillar, be arranged at intervals with and traverse, the gate road in the first coal face coal left side is the first work plane air intake lane, the gate road on right side is the first tailentry, two gate roads and the first work plane form the first U-shaped ventilation system, the gate road that the second coal-face is adjacent with the first coal-face is the first work plane Pai Wa lane, the gate road on right side is the first work plane air distribution lane, two gate roads of the second coal-face and the second coal-face form the second U-shaped ventilation system.
The described spacing distance traversing is 30～120M, and described isolated coal pillar width is 30～60M.
Coal-face U-U type ventilation system of the present invention, though need to arrange 4 gate roads and 2 work planes (cutting eye) tunnel, but there are 2 gate roads and 1 work plane (cutting eye) tunnel to reuse, the excavation work amount of work plane is basic identical with single U-shaped ventilation system in essence, with the high gas of China, the normal U+L type adopting of projecting mine, U+I type, Y type, Y type partially, double-U-shaped ventilation system is compared, the actual tunnelling engineering amount of each coal-face reduces greatly, and without gob side entry retaining, also can meet or exceed the gas control effect of above-mentioned coal-face ventilation system, be specially adapted to high gas, projecting mine, there is obvious technical advantage and promotion prospect.
