Description of the drawings
Attached drawing 1 is a kind of flow chart of the present invention.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment:
The monitoring data of mine electric method monitoring system acquisition are generally current potential or potential difference, at 3 D resistivity inverting Reason can obtain the 3 D resistivity data that can more directly reflect coal measure strata Electrical distribution situation.Conduit pipe growth course In, the zone resistance rate being affected by it can continuously decrease.The real-time change of the coal measure strata resistivity obtained by analyzing inverting Situation can effectively judge the developmental state of conduit pipe, so as to achieve the purpose that carry out early warning to analysis of possibility of water inrush.
Divide in real time automatically as shown in Figure 1, the embodiment of the present invention provides a kind of working face water damage based on mine electric method monitoring Grade method for early warning, the present invention realizes the automation and intelligence of working face water damage early warning, during working face extraction Analysis of possibility of water inrush early warning.
First according to the geologic information of stope, establish the 3 D resistivity model of coal measure strata, model be comprising The 3D data volume of resistivity value.In stope arrangement mine electric method monitoring system, start downhole data acquisition, will monitor Data synchronous transfer is to ground-based server.Monitoring number is recorded with integer i, starts season i=0 in monitoring, completion once monitors I adds 1 automatically afterwards, and the monitoring data of acquisition are stored with array d (i).Ground-based server is accessed by programme-control automatically, Obtain real-time monitoring data d (i).Using coal measure strata resistivity models as initial model m0, monitoring data are carried out with three-dimensional electricity Resistance rate inverting, the object function of inverting are as follows:
M is for the model of inverting iteration in formula, and d (m) is that given conductivity model m is carried out obtained by forward modelling Data, d (i) are real-time monitoring data, and β is regularization parameter, and W is model regularization matrix.In order to obtain object function Φ (m) minimum value with above formula is to model parameter m derivations and to make it be zero, obtains more new formula:
(JTJ+βWTW) δ m=- (JT(QA-1q-d(i))+βWTW(m-m0)) (2)
WhereinFor Jacobian matrix.Above formula is solved using Gauss-Newton method is intended, is obtained newer Inverse model.The 3 D resistivity model that inverting obtains is stored to ground-based server, inverse model is deposited with array m (i) Storage.
, it is necessary to first be carried out to first monitoring data d (1) and second batch monitoring data d (2) anti-when just starting monitoring It drills, obtains corresponding inverse model m (1) and m (2), then carry out subsequent early warning judgement again.By adjacent batch monitoring data d (i-1) 3 D resistivity model m (i-1) and m (i) and obtained by d (i) invertings are compared, and judge two according to coordinate information Whether model has overlapping region.If overlapping region is not present in model m (i-1) and m (i), next group monitoring data are come back for Inverting, and by the inverse model newly obtained with last time obtain inverse model be compared, repeat the process until obtain There are overlapping region two groups of adjacent inverse models or working face extraction finish until.If there is coincidence in model m (i-1) and m (i) Region, then for overlapping region calculate two models resistivity differences δ m (i)=m (i)-m (i-1), and judge be in δ m (i) The no point existed less than 0.If the point less than 0 is not present in δ m (i), means that gushing water hidden danger temporarily is not present, come back for The inverse model newly obtained is compared with the inverse model that the last time obtains for the inverting of next group monitoring data, and repeating should Process is until obtain the two groups of adjacent inverse models or working face extraction there are overlapping region and the middle points in the presence of less than 0 of δ m (i) Until finishing.For the point for being less than 0 in δ m (i), the local minimum r (i) of δ m (i) is found out according to coordinate information, is preserved local Minimum value coordinate position corresponding with its sends the three-level warning information for including local minimum coordinate position:" at so-and-so position There are gushing water hidden danger!”.
The local minimum r (i-1) of acquisition is once calculated before judging whether.If there is no local minimum r (i- 1) inverting of next group observation data, is then come back for, and judges whether to need to send three-level warning information, it is straight to repeat the process Until local minimum adjacent before and after two groups is obtained or working face extraction finishes.If there are local minimum r (i-1), Judge that the local minimum r (i) newly obtained and the preceding local minimum r (i-1) for once calculating acquisition are overlapped with the presence or absence of position Point.If the point that position overlaps is not present in local minimum r (i) and r (i-1), the anti-of next group observation data is come back for It drills, and judges whether to need to send three-level warning information, repeat the process until obtaining two groups of phases of the point that existence position overlaps Until adjacent local minimum or working face extraction finish.If the point that local minimum r (i) and r (i-1) existence position overlap, The coordinate position overlapped is preserved, is sent comprising the two level warning information for overlapping coordinate position:" analysis of possibility of water inrush increases at so-and-so position Greatly!”.
For the point that position in two groups of local minimums overlaps, difference s (i)=r (i)-r of two groups of local minimums of calculating (i-1), and judge to whether there is the point less than 0 in s (i).If the point less than 0 is not present in s (i), next group is come back for The inverting of data is observed, and judges whether to need to send three-level warning information and two level warning information, repeats the process until obtaining Until must being finished in the presence of the s (i) or working face extraction of the point less than 0.If there is the point less than 0 in s (i), the point less than 0 is preserved Coordinate position, send and include the level-one warning information of the point coordinates position:" analysis of possibility of water inrush further increases at so-and-so position, It is recommended that investigation!”.
Judge whether back production finishes working face, if then terminating this early warning, if otherwise coming back for next group observation number According to inverting, and judge whether to need to send warning information at different levels, repeat the process until working face extraction finishes.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way Generation, but without departing from spirit of the invention or beyond the scope of the appended claims.
