Simulation and Parameters Analysis of Fault Geological Structure for Detection in the Excavation Face

Abstract:

In order to study on the advanced detection technology and the sensitivity of the Fault geological structure based on induce polarization (IP) method, and analyze the hazards of the Fault geological structure in front of the excavation face of coal mine roadway. This paper establishes a simplified physical model of the structure and converts the model into an equivalent circuit for convenient study and then constructs an IP model of the Fault geological structure. The IP model is connected with the simulation detection model of geological abnormal mass to obtain the changed curves of the apparent resistivity and the apparent frequency under the IP mode. The curves obtained show that simulation detection results agree with the electrical parameters specified by the IP model. Therefore the basic idea of the electric method detection is verified, which will provide a feasible presupposition for the development of the coal (rock) IP effect based on the advanced detection instruments with the electric method.
