Abstract
The invention discloses a micro-seismic source combined positioning method. The objective of the invention lies in providing a micro-seismic source combined positioning method. The method is characterized in that the method employs a linear positioning method for preliminary seismic source positioning, and solves the position coordinates of the seismic source. The method comprises the steps: taking the preliminary solved position coordinates of the seismic source as iteration starting values of a Geiger positioning method for iteration calculation, enabling a positioning error to meet the requirements of an optimum solution, and finally solving the position of the seismic source. The method is used for the quick and precise positioning of the seismic source in a micro-seismic monitoring process of an underground project.
Description
Technical field
The invention belongs to underground works safety monitoring technology field, relate to a kind of micro seismic monitoring seismic source location method.
Background technology
Microseism technology is one of important technical of the underground works such as mine, water power safety monitoring.Microseism focus locus is the important parameter of On Microseismic Monitoring Technique research, to microseism seismic source location method and the research improving microquake sources positioning precision, is one of important content of On Microseismic Monitoring Technique research always.In actual field application, Geiger localization method is one of method commonly used the most, and then the time difference positions its waveform obtained by each sensor; But also exist simultaneously iterative initial value select improper and cause that solution efficiency is low, the poor problem such as even cannot to locate of Position location accuracy, select suitable initial value iteration could go out Global localization error minimum value, inappropriate initial value then may can only obtain local positioning error minimum value.The present invention is directed to this problem, have employed a kind of microseism focus combined positioning-method.
Summary of the invention
The present invention is a kind of microseism focus combined positioning-method, to realize accurately locating fast of microseism focus.The technical solution of patent of the present invention is: a kind of microseism focus combined positioning-method, specifically adopts the localization method that linear orientation method and Geiger localization method combine, it is characterized in that:
A. adopt linear orientation method to carry out preliminary seismic source location, obtain source location coordinate.
B. utilize the source location coordinate tentatively obtained, the iterative initial value as Geiger localization method carries out iterative computation, finally obtains source location.
The invention has the beneficial effects as follows: the fast accurately location being achieved microseism focus by this method, overcome the iterative initial value selection existed in the large and Geiger localization method of linear orientation error improper and cause the shortcoming that solution efficiency is low, Position location accuracy is poor.This method principle is simple, convenience of calculation, good practical effect, is applicable in underground works micro seismic monitoring.
Accompanying drawing explanation

Fig. 2 adopts human-generated explosives location to test combined positioning-method effect.
In figure: improper situation selected by 1.-initial value, 2.-select suitable initial value situation, Φ (θ)-positioning error function, θ
*-initial parameter value,
-estimates of parameters.
Embodiment
The present invention is a kind of microseism focus combined positioning-method, comprises the steps:
(1) first adopt linear orientation method to carry out Primary Location calculating to microseism focus, obtain microseism source location coordinate.
(2) initial value that focus coordinate linear orientation method calculated locates iteration as next step Geiger carries out iterative computation, finally obtains microseism source location coordinate.
Implementation column:
Adopt human-generated explosives positioning test method in certain ore deposit, adopt linear orientation method, Geiger localization method and combined positioning-method to position calculating to this microseism focus respectively, following table 1 is its location Calculation result.Result of calculation shows, combined positioning-method can realize accurately locating fast of microseism focus.
The various localization method results contrast of table 1
