Abstract: A method of determining the coal-bearing system boundary includes the following steps: firstly, determining the high-level boundaries mainly including the tectonic boundary, ore-bearing stratum and geological body distribution boundary, mixed complex boundary, etc.; secondly, determining the major boundary mainly including a fault or fault zone, giant fold or fold assemblage zone, sedimentary boundary, stratigraphic and mineral occurrence boundary, natural geography and artificial boundary, etc.. The determination of each major boundary contains the definition of its interfaces or boundaries with specific meaning among 18 types of such interfaces or boundaries. The coal-bearing system boundary is determined based on the features of the boundaries with specific meaning as well as the boundary development, mineral assemblage and spatial distribution conditions of a specific region.

Abstract: A method of intergrowing and coexisting four-in-one multi-mineral coordinated prospecting includes the following steps: firstly, implement the coordinated prospecting to identify the occurrence states, occurrence regularities and developing conditions of multiple minerals so as to realize the coordinated prospecting and evaluation for these minerals and achieve high-precision high-benefit optimal prospecting effectiveness; secondly, implement different prospecting methods and technologies in a coordinated way and implement the exploratory drilling, geophysical prospecting, information technology and other technologies in a systematic and coordinated fashion so that the implementation of prospecting works achieves the optimal configuration, realize maximum benefit, obtain sustainable optimal prospecting effectiveness with minimum input and enhance the technological level and prospecting effectiveness of multi-mineral integrated coordinated prospecting as a whole.
