Abstract
The utility model provides a gas-pressurized drainage for a mine, which is characterized in that two tunnel lanes capable of spitting and holding mine water and filling gases are dug in the mine rock near a tunnel which is easy to accumulate water in a well. A compressor is arranged at the place which is not easy to influence by water inrush, and the compressor is communicated with each tunnel lane by a pressure wind pipe. When the water surface in the tunnel lane ascends to the limit, the pressure wind is input in the tunnel lane to discharge the water. When the water inrush happens, because the tunnel lane and the pressure wind pipe do not stop working due to water flooding, the gas-pressurized drainage for a mine can drain normally, and therefore, the mine flooding of the mine can be avoided and delayed. In addition, the gas-pressurized drainage for a mine is suitable for discharging the mine water containing acid and silt.
Description
The utility model relates to a kind of device with compressed air discharge mine water, particularly a kind of device that can stand water logging.Be fit to general mine or the possible mine drainage of gushing water is arranged.
Existing mine drainage is mainly finished by the drainage system that water pump, sump and pipeline etc. are formed.Mine water is to enter the pump housing through suction water pipe, obtains energy and raise out in the pump housing.Since in the suction water pipe with the sump water surface between pressure reduction less, lift is generally five to seven meters so it absorbs water.This highly just forces water pump to install near sump.In case water bursting in mine and water yield are during greater than displacement, water pump just is on the hazard or is flooded shutdown, causes flooding the well accident.
For addressing this problem the current trend that the employing submersible pump is arranged.What the Coal Industry Press published in 84 years " has just introduced the method in the coal mine mining design handbook.But also point out: current large diving pump still the development among, when this machine examination is repaiied again the difficulty, so present submersible pump only as mine by the usefulness of the recovery rescue after flooding.
The purpose of this utility model is that a kind of mine drainage device with compressed air will be provided.It can not only be worked under the normal situation of swallet, and at water bursting in mine, still can work as usual when partly roadway is flooded.
This purpose reaches like this: near the ore deposit rock mine is easy to the tunnel of ponding, dig two and receive the cave lane of mine water and inflation in order to tell, the absolute altitude in (being referred to as " pushing cave lane " in the utility model) pushing cave lane should be lower than the absolute altitude in contiguous tunnel, its section configuration, volume size and laying mode can determine according to actual conditions.Pressure ventilation pipe, oral siphon and gutter are equipped with in the entrance in pushing cave lane, and the lower end of gutter are stretched into the lowest part in pushing cave lane.Behind the regulation device of installing geomantic omen the cave lane is sealed.
Pushing more than the cave lane and not being subject to the place installation air compressor that water bursting in mine threatens, be communicated with formation air pressing type Mine Drainage System with pushing cave lane with pressure ventilation pipe.When the water surface rose to the regulation absolute altitude in the cave lane, compressed air input pushing cave lane, water inlet pipe were closed, and draining begins.When water bursting in mine, the water yield increases severely.Though part roadway and pressure ventilation pipe are flooded, do not hinder compressed-air actuated conveying; Though pushing cave lane still keeps an anhydrous space, so drainage works is unaffected in the cave lane under water body.So just reached the purpose that still can work as usual when mine is subjected to the water damage threat.
The utility model is simple in structure, and is easy to operate, practicable automatic control.Required plant equipment, as air compressor, valve etc., market all has series of products to choose.In addition, in this device because the machinery that in water, does not move, so to row contain acid, the mine water that contains silt is also suitable.
Below by accompanying drawing the utility model is further described.
Fig. 1 is according to the air pressing type Mine Drainage System figure that the utility model proposes.
Fig. 2 is the sectional view of Fig. 1 along the 1-1 line.
Fig. 3 is the sectional view of Fig. 2 along the 2-2 line.
Fig. 4 is a geomantic omen regulation device circuit diagram.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, in near the big lane 5 of production the ore deposit rock, digging pushing cave lane 6,7, two parts are divided in this cave lane, the bottom is that retaining is used, top is for being provided with closing door 8,9 and install the geomantic omen regulation device, (this installs mainly by valve, electrode, compositions such as A.C. contactor) usefulness such as inflation, and set into aqueduct valve 11 within it, 12, pressure ventilation pipe valve 13,14, standby pressure ventilation pipe valve 15,16 and gutter 17,18, electrode 19,20,21,22,23,24.Be not subject to place (or ground) the installation air compressor 1,2 that water threatens more than 5.Connect with air main 3,4 between air compressor and the pushing cave lane, constitute the air pressing type drainage system.
When the water surface rose to 20 in 6, valve 11,14 was closed; 12,13 open 6 beginning drainings, 7 beginning retainings.Treat that the water surface reduced at 19 o'clock, then valve 12,13 is closed, and 11,14 open, 7 beginning drainings, 6 beginning retainings.So circulation endlessly.
When the water surface rises to 21 in 6, and 7 just in draining, illustrates that inflow rate of mine water increases.At this moment 21 energisings make the electric bell that is placed in compressor house send warning, and the prompting driver starts standby air compressor machine 2, and valve 16 is opened, and quicken 7 drainage speed.Wait the water surface and reduced to 22 o'clock, valve 14,16,11 is closed, and 12,13,15 open, 6 drainings, 7 retainings.This has just shortened 6,7 circulating working time.
When water continues to go up, partly produce the usefulness that interim retaining can be done in roadway and some goafs.As long as the total amount of water bursting in mine is no more than the volume in above-mentioned space and the displacement sum during the gushing water, this dewatering installation just can discharge mine disaster water successively.
Claims (6)
1. air pressing type mine drainage device of forming by air compressor, pushing cave lane, water inlet pipe and water outlet pipe, pressure ventilation pipe etc.It is characterized in that pushing the cave lane is to be in easily to receive to collect in the ore deposit rock of mine water, and air compressor is mounted in the place that is not subject to the gushing water influence.
