Fig. 2 is the hierarchical structure model figure of present example grouting consolidation effect.
Specific embodiment
Below in conjunction with the accompanying drawings and the example applied of the present invention, the present invention is further described.
Fig. 1 is the multifactor AHP integrated evaluating methods flow chart of tomography slip casting effect of the present invention.As shown in figure 1, this method bag
Include:
Step A, concludes the influence factor of influence grouting consolidation effect, sets up hierarchical structure model;
Step B, is counted to influence grouting consolidation effect factor, is calculated, utilize average value Judgement Matricies;
Step C, according to Judgement Matricies, determines grouting and reinforcing evaluation index priority weighting;
Step D, by grouting consolidation effect horizontal division grade, and makees qualitative and quantitative description.
Step E, according to opinion rating collection, is evaluated grouting consolidation effect.
Below in conjunction with instantiation, above-mentioned each step is explained.
Step A, concludes the influence factor of influence grouting consolidation effect, sets up hierarchical structure model.
In present example, the principal element of influence grouting consolidation effect is summarized as 7 aspects:Water, water temperature, slip casting
Pressure, water absorption rate, physical prospecting achievement, P-Q tracing analysis and boring and coring inspection afterwards.Based on to this grouting consolidation effect evaluate,
7 main aspects are summarized as quantitative analysis judgement and drillhole validation judges two partial objectives for.Two partial objectives for layer again respectively by
The influence of individual next level factor, is specifically shown in Fig. 2.
In fig. 2, top (general objective layer) is grouting consolidation effect evaluation (A);Partial objectives for layer (B) includes 2 factors,
I.e. quantitative analysis judges that (B1), drillhole validation judge (B2);Rule layer (C) include 7 factors, i.e. water temperature (C1), water (C2),
Slip casting terminates pressure (C3), water absorption rate (C4), physical prospecting achievement (C5), P-Q tracing analysis (C6), boring and coring inspection (C7).
Step B, is counted to influence grouting consolidation effect factor, is calculated, utilize average value Judgement Matricies.
In present example, it is assumed that (i=1,2 ..., n) are related Bi and Pi in next level, set up in B level factors
Judgment matrix, form is as follows:
The priority weight grade of each factor is determined by comparing two-by-two for each factor, represent factor on it is relatively important
Property.Its evaluation result is represented using following matrix.
Analytical structure is set up according to standard diagrams, with " collection expert analysis mode " method, collection and the live expert of consulting with
The opinion of researcher, each influence factor to grouting consolidation effect is given a mark.Scoring criterion is according to the proposed 1-9 used
As quantity yardstick, as shown in table 1.
The Saaty evaluation criterions of table 1
Judgment matrix characteristic value is calculated with eig functions in MATLAB and selects eigenvalue of maximum λ max.To structural matrix
(C.R.) consistency check is carried out.Work as C.R.<0.10, it is believed that judgment matrix has preferable uniformity, when needs are to judging square
Battle array is adjusted and corrected, and its calculation formula is as follows.C.I. the size of value, illustrates that matrix deviates the degree of uniformity
Size, value is bigger, and departure degree is bigger, and its calculation formula is as follows, and R.I. is Aver-age Random Consistency Index, and its value is such as
Shown in table 2 below.
Rule of thumb analyze, influence grouting consolidation effect factor is counted, calculated, constructed and judged using its average value

Step C, according to Judgement Matricies, determines grouting and reinforcing evaluation index priority weighting.
According to Judgement Matricies, when matrix is by consistency check, the calculating of factor priority weighting, calculating side need to be calculated
Method is as shown in table 6.
Each factor weight computational methods of table 6
Analysis collects with result of calculation more than, final to determine grouting and reinforcing evaluation index priority weighting, such as the institute of table 7
Show.The weight of each factor shown in table, is Mode of Level Simple Sequence of each factor to upper level, in order to which more preferable realize is evaluated, also
Need to carry out total hierarchial sorting.The weight that a certain layer always sorts is that the weight of this layer of single sequence is total with being under the jurisdiction of last layer time factor
The weight order sum of products.Therefore, the calculating of total weight order will successively be carried out by top to lowermost layer.Its calculation formula is such as
Shown in lower:
In formula:bjRefer to weight of the B layers of m factor to general objective;
CijRefer to Mode of Level Simple Sequence of the C layers of factor of level to upper strata Bj.
The slip casting effect grade of table 7 evaluates level index priority weighting
Total hierarchial sorting is also needed to make consistency check, successively carried out to lowermost layer by top.If B layers of factor are to A layers
The Aj Mode of Level Simple Sequence coincident indicator of factor is CIj, random index is RIj, then the uniformity ratio of layer total hierarchial sorting
Rate is:
As C.R. < 0.10, total hierarchial sorting result has good uniformity, by examining.Time destination layer has in model
B1, B22 factors, the weight to general objective is respectively 0.889,0.113, next level C layers (rule layers) shared 7 because
Element.Mode of Level Simple Sequence c of the n factor of C layers of level to upper strata BjijNumerical value is as shown in table 8.C layers of 7 factors are total by level
The weights that sequence obtains each factor are as shown in table 9.

Step D, by grouting consolidation effect horizontal division grade, and makees qualitative and quantitative description.
The present situation kept the safety in production according to China's coal-mine and working face daily management requirement, by grouting consolidation effect hierarchy level
It is divided into four grades:I security is good;II security is preferable;III security is poor;IV security extreme differences.And made qualitative and fixed
The description of amount, is specifically shown in Table 10.
The slip casting effect hierarchy level of table 10 is divided
Grade | Security I | Security preferable II | Security poor III | Security extreme difference IV |
Numerical value v | 0<v≤0.25 | 0.25<v≤0.5 | 0.5<v≤0.75 | 0.75<v≤1 |
If evaluate collection is V, comment is Un, Hazard rank is designed as " four social estate systems ", i.e.,:
V={ U1, U2..., Un}={ I, II, III, IV }
Step E, according to opinion rating collection, is evaluated grouting consolidation effect.
By the analysis to each factor of evaluation of working face, value, tool are carried out to slip casting epimere and hypomere factor of evaluation index
Body is as shown in table 11, table 12.
The epimere slip casting influence element assessment table of table 11
The hypomere slip casting influence element assessment table of table 12
Using data in table 11, slip casting epimere influence element assessment numerical value V is calculated, determines that its V value is equal to
0.34834, security preferably, is consistent with actual conditions.Model is not adjusted.
Using data in table 12, slip casting hypomere influence element assessment numerical value V is calculated, determines that its V value is equal to
0.43189, security is preferable.
