Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on this
Inventive embodiment, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, broadly falls into protection scope of the present invention.
Lakebed or river bed, after adopting sand, are reduced owing to adopting husky activity disturbance, lakebed or riverbed intensity, and quality is relative
Softer, and be difficult in the short time recover original intensity so that territory, sand basin intensity is significantly lower than territory, non-sand basin intensity.According to this
Individual feature, design is adopted husky detection instrument and is detected lakebed and riverbed, determines and adopts husky scope and Cai Sha degree, and passes through geology
Data and boring and coring situation analysis determine adopts the husky degree of depth.
Embodiment one
Fig. 1 adopts the flow chart of the detection method of sand for the lake, a kind of river that the embodiment of the present invention one provides.As it is shown in figure 1, should
Method mainly comprises the steps:
Step 11, select the connecting rod of corresponding length according to the depth of water of sensing point, by the end of this connecting rod through punching
It is connected with probe with pallet, sounding rod successively after the perforate of hammer.
Before carrying out adopting husky detection, need to carry out the design of survey line, sensing point, and the location etc. of sensing point, it is possible to use
The aids such as GPS alignment system, compass.
The region design detection circuit of detection can needed, require according to a determining deviation at detection line according to detection accuracy
Mark sensing point on road, and measure the coordinate record of sensing point from plane graph and become table, as the coordinate foundation in actual observation.Visit
The selection principle on survey line road is to select to adopt the husky movable region having a negative impact underwater mining most probable to arrange, due to coal seam
Superficial part region bedrock thickness of appearing is little, and coal seam distance unconsolidated formation is near, so typically choosing coal seam superficial part region of appearing to arrange survey line.
Generally, all detect according to survey line, the sensing point of design, but in actual observation, especially in the feelings of flowing water
Under condition, it is accurately positioned and seems the most difficult, therefore can suitably adjust sensing point in the case of meeting test accuracy requirement.After adjustment
Coordinate need to carry out accurate recording.
If detection process runs into the situation impact detections such as " net cage ", island, the water plant breeded fish, can take to abandon,
Walk around, adjust the measure process such as sensing point；Can suitably increase sensing point adopting husky significantly region, the layout of sensing point is with permissible
Judge that adopt sand shadow ringing range size is principle.Adopt the circle of husky influence area generally rule, straight to circle in detection process
Footpath can be estimated and keep a record.
After reaching predetermined sensing point, first the depth of water of this sensing point is measured, such as, utilize sash weight vertically to put into water
In, when sash weight just " bottoms out ", the scale carried on line according to sash weight reads depth of water Hs the record of this measuring point.
Connecting rod length can be adjusted according to the depth of water of sensing point (needing to ensure that the whole body of rod after connecting all soaks
Enter in water), such as, if a length of 1 meter of single connecting rod, and the depth of water detected is 10-20 rice, then can by many connecting rods even
After connecing, then it is connected with probe with punching hammer, pallet, sounding rod.
For example and without limitation, punching hammer, pallet, sounding rod can use following specification with probe: punching hammer is heavy
10KG, volume is about 0.002m3, weight diameter 0.2 meter；Probe is conical probe, and its cone angle is 60 °, a diameter of 0.04 meter, touches
Feeler lever is directly 0.025 meter, a length of 0.9 meter.
Step 12, the body of rod that above-mentioned connection forms is inserted perpendicularly in water, and guarantees that its maximum deflection degree is less than threshold value.
Under normal circumstances, need to ensure that the whole body of rod submerges, and guarantee that its maximum deflection degree is less than threshold value
(such as, 2%).
Further, for the ease of operation, one drop handle can be set on the top of connecting rod, by pulling on drop handle
Stay cord guarantees that the body of rod keeps plumbness.
Step 13, utilize punching hammer with pallet described in predetermined frequency hammering, until the depth of penetration of probe is little after hammering
In or equal to threshold value, and record hammer number now.
For the ease of operation, can arrange at the two ends of punching hammer can the link of lanyard, and in connecting rod by subterminal
Position arranges a draw-in groove, in order to controls the maximum lifting height of punching hammer, and guarantees the maximum lifting height one lifted each time
Cause；Concrete numerical value can set according to actual demand, and such as, maximum lifting is highly set to 0.5 meter by the present embodiment；And
And, in order to ensure the accuracy of information, when using punching hammer hammering, hammering to be prevented bias, feeler lever tilt or laterally rock.
It addition, hammering frequency and depth of penetration threshold value in this step can be set according to actual demand, example
As, hammering frequency could be arranged to 15～30/ points；Depth of penetration threshold value could be arranged to 0.03 meter.
Hammering records lining rope scale after terminating on the basis of the water surface, and lining rope scale adds the total length of upper lever and is depth measurement Hc,
The depth measurement record converted is in result of detection log, and this form can use the form shown in table 1:
Table 1 result of detection log
In order to ensure the accuracy of data, can repeatedly test at identical sensing point, take depth measurement higher value conduct
The final result of detection of this measuring point.
If the current sensing point of step 14 meets, the number of times of hammering >=n time, the total depth >=s rice of probe injection and sensing point
At least two condition in the depth of water >=mean depth × m%, then judge that current sensing point carried out adopting husky activity.
The value of n Yu s of this step can be multiple environment is tested after obtain empirical value, mean depth can
Think that m% can be set to 20% not by adopting the water level meansigma methods that sand shadow rings near sensing point.
For example and without limitation, it is tested for mud, takyr soil, shallow water and field environment, it is thus achieved that corresponding
The value of n Yu s；Test numerical value as in the table below:
Hammering test under table 2 varying environment
When environment in table 2 is tested, the action of punching hammer hammering is all carried out above at the water surface, during dropping hammer
Substantially not having energy loss, therefore hammering dynamics is significantly greater than situation in water.As can be seen from Table 2: when blow counts >=7
Time, each hammering degree of depth is basic≤3cm, and injection difficulty；In mud and shallow water, depth of penetration is maximum, front 7 injection total depths
It is not more than 0.7 meter.Therefore, the value of n Yu s can be set to 7 and 0.7 by the embodiment of the present invention.
Further, for the ease of understanding the present invention, below in conjunction with punching plumb rule lattice the detection principle of the present invention done into
One step introduction.
Lakebed or river bed, after adopting sand, are reduced owing to adopting husky activity disturbance, lakebed or riverbed intensity, and quality is relative
Softer, and be difficult in the short time recover original intensity so that territory, sand basin intensity is significantly lower than territory, non-sand basin intensity.According to this
Individual feature, design is adopted husky detection instrument and lakebed and riverbed are adopted husky situation is detected.
The effect of punching hammer is hammering pallet, and passes under power so that the probe of bottommost can injection river (lake) bed,
But, punching hammer weight can not too high can not be too low, otherwise, it is impossible to ensure test accuracy.
Punching hammer weight 10Kg in the embodiment of the present invention, volume is about 0.002m3, weight diameter 0.2 meter, height of drop is
0.5 meter, whole process of dropping hammer all is carried out in water.When punching hammer falls in a liquid, by gravity, buoyancy and viscosity resistance
Effect, is reduced to the iron ball of diameter 0.2 meter.
Unlimited extent and without in the liquid of whirlpool, be the ball of r according to Stokes' law, i.e. radius, with speed v
When the Liquid that the coefficient of viscosity is η, the viscosity resistance size of ball institute liquid body is:
FViscous=6πrηv；
Wherein, coefficient of viscosity η depends on character and the temperature of liquid；Liquid in the present embodiment is water, then different temperatures
Coefficient of viscosity η corresponding to water, can be found in following table:
| Temperature (DEG C) | Coefficient of viscosity η (moors) | Temperature (DEG C) | Coefficient of viscosity η (moors) | Temperature (DEG C) | Coefficient of viscosity η (moors) |

The coefficient of viscosity of water under table 4 different temperatures
This embodiment assumes that water temperature is about 20 degree, taking the coefficient of viscosity according to table 3 is 0.00101 pool, then viscous suffered by weight
Resistance hysteresis:
FViscous=6×3.14×0.2×0.00101·v=3.8×10-3v；
If terminal velocity during weight decline H=0.5m is vTail, according to kinetic energy theorem:
G·H-FFloating·H-FViscous·H=0.5mvTail 2；
Due to FViscousLinear with v, approximation is averaged as FViscous=0.5×3.8×10-3vTail=1.9×10-3vTail, simultaneously
FFloating=ρLiquidgVRow=19.6N, G=mg=10 × 9.8=98N, H=0.5m, tries to achieve:
vTail≈ 2.8m/s, terminal FViscous whole=1.064×10-2N；
If punching hammer is F to lakebed impulsive force, further according to momentum theorem:
(F-G+FFloating+FViscous whole) t=m vTail；
Take t=0.5s, try to achieve F=134.4N.
It addition, probe diameter is 0.04 meter, then the pressure that hammering moment produces is
P=F/S=134.4/3.14 × (0.02)2≈107kPa。
The allowable bearing 140～350kPa of rough sand, middle sand and fine sand, and with husky density and the close phase of water content
Closing, general density is low, the sandy soil low bearing capacity that water content is high；The embodiment of the present invention produces pressure holding less than intact sandy soil
Load power, but when sandy soil bearing capacity after disturbance drastically declines, the punching hammer weight therefore designed is suitable.
After determining that according to said method a certain sensing point carried out adopting husky activity, it is also possible to further determine that and adopt sand deeply
Spend and adopt husky thickness: wherein it is determined that adopt husky thickness two ways: 1) by the unconsolidated formation earth formation situation judgement in territory, sand basin
Adopt the husky degree of depth, concrete: according to existing borehole formation configuration data, by the buried depth of sand bed, thickness and particle diameter to adopting the husky degree of depth
Calculate；Judge to adopt the husky degree of depth by territory, sand basin unconsolidated formation earth formation situation.2) diameter of husky scope is adopted in detection, thus
Determine and adopt the husky degree of depth；" building, water body, railway and main roadway coal column stay and set and mining pressed coal code " enumerates unconsolidated formation
Traveling angle universal law see table:
| Degree of depth h/m | ≤10 | 10～20 | 20～40 | 40～60 | ≥60 |
| Traveling angle ψ (aqueous less)/(°) | 45 | 50 | 55 | 60 | 65 |
| Traveling angle ψ (aqueous bigger)/(°) | 40 | 45 | 50 | 55 | 60 |
Table 4 unconsolidated formation traveling angle
Husky aqueous relatively big owing to adopting in lake, river, and adopt the husky degree of depth and substantially concentrate between 10～20, therefore, according to loose
Layer traveling angle ψ=45 ° calculate, when known adopt the husky a diameter of R of scope under conditions of, adopt husky depth H ≈ 0.5R.It addition, when detecting
After adopting the diameter of husky scope, also can verify according to the husky thickness of adopting that first method is determined by second method, it is achieved essence
Really judge to adopt the husky degree of depth.
After determining and adopting the husky degree of depth, then can determine according to this sand bed architectural characteristic and adopt husky thickness, and can be according to detecting
The security situation in underwater mining district is judged by above-mentioned data, ensures that the safety of underwater mining.
Such scheme based on the present invention, is detected the husky situation of adopting in a certain underwater mining district, and according to spy
The data measured carry out the judgement of safety.
Before this, the associated safety situation that lake, river is adopted sand is introduced:
Due to primary deposit effect, unconsolidated formation from the multi-layer compound structure that the most all there is water-bearing layer, water barrier is alternate,
And generally there are in deep that a layer thickness is big and the water barrier of Stable distritation, it is each aqueous that this water barrier can intercept its top substantially
Water-bearing layer, its underpart is fed by layer, and such water barrier is referred to as region key water barrier.Due to region key water barrier
Exist, the unconsolidated formation water-bearing layer of mining impact is mainly water-bearing layer, its underpart.According to coal mining under water bodies research experience for many years, pine
Dissipating the index in region key water barrier (group) of layer: monolayer gross thickness is more than 10m, the liquidity index of clay is less than 0.5, and folder is husky little
In 3m, regional stability is distributed.
According to above theoretical, when lake region, river is adopted sand especially sand is adopted in superficial part outcrop area in coal seam, in order to ensure underwater mining district
The safety in safety coal mining district, adopt sand and can not touch unconsolidated formation region key water barrier.General relatively owing to adopting the bore diameter of sand
Greatly, more than 30cm, and adopt sand person afterwards to boring do not take any measure, cause and not only cause sand bed upper formation after adopting sand
Depression, and lake water is by boring UNICOM each stratum, softens further through each soil layer of disturbance, can cause " water barrier " time serious
Lose water isolating completely.Therefore, the husky degree of depth is adopted when touching region key water barrier in detection lake region, river, this region underwater mining danger
Danger coefficient increases.
The lakebed of the detected lake region of the present embodiment is deep loose alluvium structure, multiple (such as, 4) contain, water proof
Layer composition.Water barrier is to intercept surface water and each loose aquifer water in lake to burst into the crucial stratum of mine；Wherein, 3-
4 water barriers are region key water barrier.Under normal circumstances, 3-the 4th water barrier can intercept surface water and each water-bearing layer on it.
According to hydrogeologic data and mining Practice experience, this region waterproof safety coal (rock) can be changed into sand prevention safety coal (rock)
Post, to improve resource recovery.This lake exists all the time adopts husky situation, owing to being not related to shallow mining in the past, does not cause
Enough attention, but the district of underwater mining in recent years improves mining up per limit pilot production, adopts husky activity serious threat downhole safety exploitation, can
Husky activity can be adopted whether can be to staying husky peace of setting up defences to find out further to staying sand prevention safety coal (rock) post set to cause obstruction
Full coal (rock) post has a negative impact, and has carried out this lake region detecting on the spot and analyzing.
Side line and sensing point to this lake region are designed: survey line is along near the mining up per limit of superficial part outcrop area, lake region, altogether
Design 25 measuring points.

Secondary, the depth of water is also deep relatively around, and removes outside #22, and depth of penetration is all higher than 0.7 meter, and wherein measuring point #24 and #25 detects ooze
The degree of depth has exceeded 1.5m especially, illustrates to adopt husky phenomenon obvious, and judges at measuring point #1, #2, #14, #17, # according to analysis before
24, #25 all occurred to adopt husky activity.
At sensing point #22, although blow counts meets the condition of >=7 times, but it is unsatisfactory for >=the condition of the depth of penetration of 0.7m；
Meet the condition of the ooze degree of depth >=0.7m at #23, but be unsatisfactory for the condition of blow counts >=7 time.At two, the depth of water is the deepest, and injection
The degree of depth is the deepest, it is taken as that the probability adopting sand at measuring point #22 with #23 is big, it is also possible to channel cleanout causes.
But in view of concrete condition: be by chance river course at measuring point #22 Yu #23, it can thus be assumed that it is the result of that probe that causes of desilting.
The destructiveness of lakebed is not adopted husky big by desilting, but is also required to carry out the precautionary measures when down-hole coal excavation.
After determining and adopting husky situation, then can further determine that and adopt the husky degree of depth and adopt husky thickness.Near with actual survey line
Borehole data makes outcrop area Quaternary loose soils part sectioned view, mends may hole in conjunction with detection territory, sand basin scope and the hydrology
Coring situation, analyzes and determines that sensing point adopts the husky degree of depth, as in figure 2 it is shown, wherein, 5 arc areas represent adopts husky scope to its result,
Remaining shadow region represents sand bed region.
According to Fig. 2, the position of the most shallow degree of depth is near #2 point, and its degree of depth is at 20～30 meters, and high depth is #23 point
With #24 point position, its degree of depth is at about 50～60 meters.And according to the surface layer data being obtained ahead of time, about 40m is for reaching pine
Dissipate the basal and lower beds of the 1st water barrier of layer；About 60m, be the 2nd every bottom, the 3rd upper layer position, water-bearing layer, therefore, it is husky movable to adopt
Do not destroy the 3rd and the 4th water barrier temporarily, its water-resisting property is not adversely affected.
It addition, according to borehole data, in outcrop area, Quaternary loose soils thickness is generally about 120m, and loose
Bottom floor, lean clay is inhibited to the growth of the leaking crevice belt in underwater mining district, it is contemplated that leaking crevice belt will not be with
Adopt husky position to be mutually communicated, form conduit pipe.Therefore adopt husky activity not interfere with and stay husky safety coal (rock) post of setting up defences, to this lake
Lower coal mining does not the most temporarily result in adverse effect.
