Description
Technical field
The invention belongs to large mining depth high artesian mine water management technical field, it is related to a kind of large mining depth high artesian mine
Zone isolation release prevention and control water system.
Background technology
Large mining depth high artesian mine and the mine of complicated hydrogeological conditions are pressed《Safety regulations in coal mine》273rd article will
Ask, it is necessary to which sluice gate is set, carry out subregion isolation.When mine generation coal seam bottom water bursting floods exploiting field, waterflooding is flat or even floods mine
Catastrophe when, can play reduce catastrophe scope purpose, realization harness the river, on one side produce, reduction mine disaster degree with
The economic loss of coal mining enterprise.
Large mining depth high artesian mine hydraulic pressure is far longer than 5.0MPa, at present, and in the market is not born hydraulic pressure also and is more than
The ripe approved product of 5.0MPa sluice gate.According to《Safety regulations in coal mine》273rd article of regulation, is more than in no hydraulic pressure
5.0MPa sluice gate approved product, can in addition be installed in proper drainage system-based with autonomous power supply system and draining energy
Power is not less than the immersible pump of maximum flooding quantity.But the Large diving pump of the high discharge capacity of big ability is higher to the water quality requirement of draining,
Under mine catastrophe case of emergency, water quality is poor；Further, since its power consumption is very big, easily line voltage formation is impacted, power network
Voltage is not sufficiently stable, and fault of water pump easily occurs, causes drainage efficiency low, and influence plays the effect of emergency management and rescue.
The content of the invention
Isolate release prevention and control water system it is an object of the invention to provide a kind of large mining depth high artesian pit zone, work as mine
When generation gushing water floods, diminution catastrophe scope can be played, mine disaster degree and the economic loss of coal mining enterprise is reduced.
The technical scheme is that：Large mining depth high artesian pit zone isolation release prevention and control water system, including main shaft,
Auxiliary shaft, coal seam and stage horizontal main entry, it is big that stage horizontal main entry includes a horizontal main entry, bottom level main entry and by-level
Lane.One horizontal main entry is provided with horizontal pump house, and bottom level main entry is provided with bottom level pump house, and by-level main entry is provided with middle water
Flat pump house.One horizontal pump house is connected to ground by discharge pipe line, and bottom level pump house is connected to ground by line pipeline.In
Between horizontal main entry and bottom level main entry be respectively equipped with floodgate wall, floodgate wall is provided with sluice gate, and sluice gate is provided with No. 1 drain water circuit
With No. 2 drain water circuits.No. 1 drain water circuit and No. 2 drain water circuits are equipped with high pressure water control valve.The bottom water of bottom level main entry
Put down No. 1 drain water circuit and be connected to bottom level pump house, No. 1 drain water circuit of by-level main entry is connected to by-level pump house.
No. 2 drain water circuits of bottom level of bottom level main entry are connected to by-level pump house, No. 2 drain water circuits of by-level main entry
It is connected to a horizontal pump house.
The quantity of by-level main entry is 0~5, and No. 1 drain water circuit of each by-level main entry is connected to respective water
The pump house of flat main entry, No. 2 drain water circuits of each by-level main entry are connected to the pump house of a by-level main entry, the superiors
No. 2 drain water circuits of by-level main entry are connected to a horizontal pump house.When the quantity of by-level main entry is zero, bottom level is big
No. 2 drain water circuits in lane are connected to a horizontal pump house.The caliber of No. 1 drain water circuit and No. 2 drain water circuits and the horizontal main entry in place
Horizontal pump house main drainpipe road diameter it is identical.The pressure-bearing scope of sluice gate is 2.5~5.0MPa.
The present invention in mine stage horizontal main entry by installing floodgate wall, and floodgate wall is provided with 5.0MPa sluice gate, water
The drain water circuit of two, a drain water circuit are installed in gate（No. 1 drain water circuit）Guide to this horizontal pump house, another tapping pipe
Road（No. 2 drain water circuits）To upper one horizontal pump house, drain water circuit installs control high pressure valve additional.When gushing water occurs for deep horizontal,
Sluice gate is closed, when water inrush quantity exceedes deep horizontal pumping room drainage ability, the control high pressure valve on No. 1 drain water circuit is utilized
Control bleeder quantity to be no more than this horizontal pumping room drainage ability, a part of water is discharged using this horizontal drainage system.With sluice
Water level rises in door, according to law of connected vessels, and water level rises in No. 2 drain water circuits, when water level rises to level of upper stage, under
Horizontal component disaster water is leaned on from pressure by No. 2 drain water circuits and lets out horizontal pump house of upper stage, utilizes horizontal row water system of upper stage
System draining.As water inrush quantity continues to increase, water level continues to rise, by the progressively upward level segment diversion of this principle, using upper
One stage horizontal drainage System drainage.
The present invention's effective is：1. when water bursting disaster occurs for mine, each stage, horizontal main entry can all realize disaster
Region is quickly isolated, and actual hydraulic pressure is respectively less than the maximum hydraulic pressure 5Mpa that sluice gate is born, solve the high hydraulic pressure mine of large mining depth without
Method uses the problem of in the market sluice gate approved product.2. by sluice gate two drain water circuits within the walls, low-level pump will be exceeded
The water of room drainability, from last horizontal pump house is pressed onto, is unlikely to flood lower level, sluice is outdoors using law of connected vessels
Producing region can continue to production.3. multiple horizontal drainage system capabilitys can be played simultaneously, the operating flexibility improved,
When total drainability is more than water inrush quantity, level and mine will not be flooded.If 4. water inrush quantity is excessive, more than each horizontal row water system
During total drainability of uniting, flooding time can be delayed, be that personnel in the pit's safe escape strives for enough escape times.5. reduce prominent
Floods become scope, reduce mine disaster degree and the economic loss of coal mining enterprise.
