Creating Forecast Maps of the Spatial Distribution of Dangerous Geodynamic Phenomena Based on the Principal Component Method

Abstract

Subject matter of the research is mining and geological subsurface objects use in the conditions of the DGDE possibility. Scope of research is the regularities of spatial distribution of geological objects properties, causing DGDE in the mining enterprise. The purpose of research is to map the mining enterprise territory subject to DGDE using the method of objective determination of weight coefficients and influencing factors. The main tasks: establish the size of the operational territorial units (OTU) and discretization of the research area; determination of the weight coefficients of the factors influencing the process of the DGDE occurrence formation on the subsurface territory; create a mathematical expression for a generalizing value determining that characterizes the degree of adverse factors coincidence, and therefore the risk rank of the DGDE occurrence.
