Description
Technical field
The invention belongs to large mining depth high artesian mine water management technical field, relate to a kind of large mining depth high artesian pit zone isolation release prevention and control water system.
Background technology
The mine of large mining depth high artesian mine and complicated hydrogeological conditions, by " safety regulations in coal mine " the 273rd article of requirement, must arrange sluice gate, carries out subregion isolation.When mine generation coal seam bottom water bursting flood exploiting field, waterflooding put down the catastrophe of even flooding mine time, the object reducing catastrophe scope can be played, realize harnessing the river and producing, the economic loss of minimizing mine disaster degree and coal mining enterprise.
Large mining depth high artesian mine hydraulic pressure is all far longer than 5.0MPa, at present, market is not also born the approved product that hydraulic pressure is greater than the sluice gate maturation of 5.0MPa.According to " safety regulations in coal mine " the 273rd article regulation, the sluice gate approved product not having hydraulic pressure to be greater than 5.0MPa, can install in addition and have autonomous power supply system and drainability is not less than the submersible pump of maximum flooding quantity in proper drainage system-based.But the water quality requirement of Large diving pump to draining of large ability high discharge capacity is higher, and under mine catastrophe case of emergency, water quality is poor; In addition, because its power consumption is very large, easily formed line voltage and impact, line voltage is stable not, easily occurs fault of water pump, causes drainage efficiency low, and impact plays the effect of emergency management and rescue.
Summary of the invention
The object of this invention is to provide a kind of large mining depth high artesian pit zone isolation release prevention and control water system, when mine generation gushing water floods, can play and reduce catastrophe scope, reduce the economic loss of mine disaster degree and coal mining enterprise.
Technical scheme of the present invention is: large mining depth high artesian pit zone isolation release prevention and control water system, comprise main shaft, auxiliary shaft, coal seam and the large lane of stage level, the large lane of stage level comprises a large lane of level, the large lane of bottom level and the large lane of by-level.The one large lane of level is provided with horizontal pump house, and the large lane of bottom level is provided with bottom level pump house, and the large lane of by-level is provided with by-level 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.The large lane of by-level and the large lane of bottom level are respectively equipped with floodgate wall, and floodgate wall is provided with sluice gate, and sluice gate is provided with No. 1 drain water circuit and No. 2 drain water circuits.No. 1 drain water circuit and No. 2 drain water circuits are equipped with high pressure water control valve.Bottom level No. 1 drain water circuit in the large lane of bottom level is connected to bottom level pump house, and No. 1 drain water circuit in the large lane of by-level is connected to by-level pump house.Bottom level No. 2 drain water circuits in the large lane of bottom level are connected to by-level pump house, and No. 2 drain water circuits in the large lane of by-level are connected to a horizontal pump house.
The quantity in the large lane of by-level is 0 ~ 5, No. 1 drain water circuit in the large lane of each by-level is connected to the pump house in the large lane of respective level, No. 2 drain water circuits in the large lane of each by-level are connected to the pump house in a large lane of by-level, and No. 2 drain water circuits in the large lane of the superiors' by-level are connected to a horizontal pump house.When the quantity in the large lane of by-level is zero, No. 2 drain water circuits in the large lane of bottom level are connected to a horizontal pump house.No. 1 drain water circuit is identical with the diameter on the horizontal pump house main drainpipe road in the large lane of place level with the caliber of No. 2 drain water circuits.The pressure-bearing scope of sluice gate is 2.5 ~ 5.0MPa.
The present invention is by installing floodgate wall in the large lane of mine stage level, floodgate wall is provided with the sluice gate of 5.0MPa, the drain water circuit of two is installed in sluice gate, article one, drain water circuit (No. 1 drain water circuit) guides to this horizontal pump house, another drain water circuit (No. 2 drain water circuits) is to a upper horizontal pump house, and drain water circuit installs control high pressure valve additional.When deep horizontal generation gushing water, close sluice gate, when gushing water amount exceedes deep horizontal pumping room drainage ability, utilize the control high pressure valve on No. 1 drain water circuit to control bleeder quantity and be no more than this horizontal pumping room drainage ability, utilize this horizontal drainage system to discharge a part of water yield.Along with water level in sluice gate rises, according to law of connected vessels, in No. 2 drain water circuits, water level rises, when water level rises to level of upper stage, lower horizontal component disaster water lets out horizontal pump house of upper stage by No. 2 drain water circuits by self-pressure, utilizes horizontal drainage System drainage of upper stage.Along with gushing water amount continues to increase, water level continues to rise, and by the progressively upwards level segment diversion of this principle, utilizes horizontal drainage System drainage on last stage.
Of the present invention effective: 1. during mine generation water bursting disaster, each large lane of stage level all can realize disaster region and isolate fast, actual hydraulic pressure is all less than the maximum hydraulic pressure 5Mpa that sluice gate bears, and solves the difficult problem that large mining depth height hydraulic pressure mine cannot use sluice gate approved product on market.2. by sluice gate two drain water circuits within the walls, the water yield exceeding low-level pumping room drainage ability being utilized law of connected vessels from being pressed onto last horizontal pump house, being unlikely to lower level to be flooded, the Production Regional outside sluice gate can continue to produce.3. can play multiple horizontal drainage system capability, the operating flexibility that improve simultaneously, when total drainability is greater than gushing water amount, level and mine can not be flooded.If 4. gushing water amount is excessive, when exceeding the total drainability of each horizontal drainage system, flooding time can be delayed, for personnel in the pit's safe escape strives for enough escape time.5. reduce gushing water catastrophe scope, reduce the economic loss of mine disaster degree and coal mining enterprise.
