Description
Technical field
The present invention relates to a kind of integral harness method of mining, and in particular to underground in a kind of open air trestle exploitation
The comprehensive control measures of mining phase surface water and groundwater, can be on the transition from open-pit of the industry such as black, coloured, coal, chemical industry ground
Lower mining is extensively applied.
Background technology
During the open air trestle mining underground mining stage, top is the recessed open-air pit of depth of remaining.Open-air pit gathering ground
Product is very big, often up to hundreds thousand of square metres.Atmospheric precipitation directly affects subdrainage, and during heavy rain, flood peak is swift and violent, short duration flood peak
Amount is especially big, and open-air pit charge for remittance amount greatly, to underground mining serious threat is brought.Such as 1984, ShaoXing,ZheJiang drenches small piece of land surrounded by water iron ore to be occurred
Because of storm flood, cause mine to be flooded；1969, Liaoning Huludao City pine tree fourth of the twelve Earthly Branches molybdenum ore in a rainfall, because of underground
Water door problem, causes to flood well accident, stops production and processes up to more than a year.Underground mine being harnessed the river open air trestle recovery of subterranean of become
One important topic of mining phase, by industry common concern.
Underground mining stage flood in order to solve the problems, such as open air trestle mining type,《Coloured mining and metallurgy》In August, 2010
" brief talking open air trestle exploitation Flood Control Problem " text delivered has been made to inquire into the open air trestle exploitation method of harnessing the river.By edge
Subside excavate outside scope tidal channel, the important roadway in underground of excavating plant periphery and underground mining arranges the measures such as water dam and carries out
Flood control is harnessed the river.《Metal mine》Describe in " Guilaizhuang ore deposit open air trestle safety and high efficiency " that 1st phase in 2012 delivers
In the ore deposit open air trestle recovery process of Guilaizhuang, catch pit is arranged by earth's surface open-air pit bottom, water is set in the stage casing of down-hole point 3
Storehouse pumping drainage.
Above-mentioned existing method of prevent floods by water control is all locality and not into system, it is difficult to meet open air trestle mining underground
Demand of the mining phase in heavy rain season integral harness, it is impossible to effectively prevent mine from flooding the generation of the water damages such as well.
The content of the invention
The purpose of the present invention is aiming at the problems referred to above of prior art presence and provides one kind collection section, anti-, row, thin, storage
Various technologies of harnessing the river are integrated, and can not only effectively administer surface water, and can prevent and treat the open air trestle exploitation of underground water
Middle underground mining stage integral harness method, can be prevented with the water damage in underground mining stage in the exploitation of effectively solving open air trestle
Only mine floods the generation of the water damages such as well.
To realize the above-mentioned purpose of the present invention, underground mining stage integral harness in a kind of open air trestle exploitation of the invention
Method is achieved through the following technical solutions：
1）Cut-off ditch is built outside underground mining moving belt scope line：In order to reduce openpit charge for remittance, in underground mining movement
Cut-off ditch is built outside band scope line, and periodically repairerment maintenance is carried out to it, can so be allowed surface water to be concentrated and drain into openpit
Outside, do not allow earth's surface charge for remittance to enter openpit, the arrangement of Cut-off ditch must be according to actual landform, and the size of Cut-off ditch is according to reality
Border landform and the hydrological data with reference to catchment area and location are computed checking and determine after flood discharge capacity.
2）Catch pit is set in open-air pit bottom：Catch pit is set in open-air pit bottom, water pump is installed in catch pit, using water
The charge for remittance collected in catch pit is drained into stope ground off-balancesheet by pump in real time；The size of the catch pit and the selection of water pump are according to outdoor
The catchment area in hole and ore district hydrogeologic condition are calculated and determined.
3）Underground mining vertical shaft pumping drainage facility：In the underground mining horizontal transport lane of underground mining winding shaft bottom
Interior installation lower shaft pumping plant；Because open air trestle mining is at the underground mining stage, usual mining depth is larger,
A upper shaft pumping plant should be at least set up in the underground mining horizontal transport lane on underground mining winding shaft top, with alleviation
The discharge pressure of portion's vertical shaft pumping plant；Underground water burst is drained into by stope earth's surface by lower shaft pumping plant, the relay of upper shaft pumping plant
Outward.
Described lower shaft pumping plant, the draining of upper shaft pumping plant are set up defences must carry out storage row's EQUILIBRIUM CALCULATION FOR PROCESS, and meet
The pit maximum flooding quantity of 24h storm frequencies is discharged in 20h, lower shaft pumping plant, the water pump of upper shaft pumping plant is determined therefrom that
Number of units；Underground mining stage pit maximum flooding quantity is heavy rain runoff amount, the underground for importing open-air pit in open air trestle exploitation
Swelling water yield sum.
4）Spilled water hole is arranged：In open-air pit highwall bottom position, spilled water hole is opened up, bottom and the underground mining of spilled water hole are carried
The underground mining horizontal transport lane for rising silo bottom communicates, spilled water hole will open-air pit side slope charge for remittance concentrate under let out to being provided with bottom
The underground mining horizontal transport lane of vertical shaft pumping plant.
5）Spilling water well is arranged：Spilling water well, spilling water are built in the underground mining horizontal transport lane for installing lower shaft pumping plant
Between underground mining winding shaft, spilled water hole, the suitable for reading of spilling water well communicates well location with open-air pit bottom.When minimum pumping plant level
Due to unpredictable flood, when unavoidably being flooded, water burst can be back to open-air pit bottom, it is to avoid underground mining by spilling water well
More tunnels are flooded.
Water door is set up in underground mining horizontal transport lane between spilling water well and spilled water hole, can be closed in heavy rain season
Close water door, protection down-hole visual plant, facility.
In heavy rain season, draining quantity of sand and mud is big, and in lower shaft pumping plant, upper shaft pumping plant pumping plant desilting is set up respectively
System.
Underground mining stage integral harness method is adopted after above technical scheme in a kind of open air trestle exploitation of the present invention,
Have the advantages that：Comprehensive employing is cut, prevents, arranging, dredging, storing up multi-pronged anti-aggregate measures of harnessing the river, and is mainly opened by underground
Adopt Cut-off ditch outside moving belt scope line, the catch pit of open-air pit bottom, underground mining vertical shaft pumping drainage facility, spilling water well,
The facilities such as spilled water hole composition integrated system come administer open air trestle exploitation in the underground mining stage surface water and groundwater.
Cut-off ditch wherein outside underground mining moving belt scope line can reduce openpit charge for remittance, effectively block periphery
Water；The catch pit of open-air pit bottom is effectively reduced and drains into groundwater run off, reduces drainage underground pressure；Underground mining vertical shaft pumping plant
Pumping equipment can will import the heavy rain runoff amount of open-air pit, underground water water burst and be ultimately discharged into earth's surface；Spilling water well can be inevitable
When dangerous situation occurs, underground water burst is drained into into earth's surface；Water door is important water proof equipment, can protect down-hole visual plant,
Facility is from water damage.
