Method for explaining active fault moving strength and growing directions through artificial earthquake

Abstract

The invention discloses a method for explaining active fault moving strength and growing directions through an artificial earthquake. The method comprises the steps that firstly, active fault growing tendencies are determined; secondly, active fault moving strength is determined. According to the method, characteristics and laws of an active fault can be found, changes of the characteristics and laws of the active fault can be predicted, and the method has importance significance in reducing geological disasters caused by the active fault and guaranteeing long-term living and development of human beings; in terms of research on moving relationships between earthquakes and modern constructions, the method can promote development of seismology and improve earthquake prediction scientificity; because the active fault has close relationships with coal mine safety production, the method can be adopted to explore extension and distribution characteristics of the active fault, prevent shafts and roadways from being built on an active fault zone and provide reliable geological evidence to coal mine construction.

Description

technical field [0001] The invention relates to a method for interpreting the activity intensity and growth direction of active faults, in particular to a method for interpreting the activity intensity and growth direction of active faults by artificial earthquake. Background technique [0002] The current methods for analyzing active faults mainly use technologies such as geomorphological analysis, geological exploration, seismic exploration and remote sensing interpretation. Geomorphological analysis mainly grasps the development of active faults from the macro and surface; geological exploration mainly uses drilling methods to investigate structures and strata, but it is powerless to explore loose active faults; Interpretation, but its interpretation marks are limited, superficial and variable, which increases the uncertainty of interpretation results. [0003] Artificial seismic technology currently focuses on the static interpretation of active faults. Generally, it is...

Problems solved by technology

[0003] Artificial seismic technology currently focuses on the static interpretation of active faults. Generally, it is qualitatively determined whether it is an active fault based on the newness and oldness of the fault-dislocation strata. There is no comprehensive analysis of seismic geological information, and the change process and growth trend of active fault activity intensity cannot be determined. , unable to provide geological basis for natural earthquake prediction research, urban base stability evaluation, coal mine safety production, etc.

[0004] From the above analysis, it can be seen that the current active fault analysis technology cannot well interpret the activity intensity and growth direction of active faults. There is a need for a method that can interpret the activity intensity and growth direction of active faults, which is conducive to early prevention and decision-making, but there is no report in the prior art
