Abstract:

Coal resources exploration in the complex geologic conditions areas is one focus of coal resources exploration in the Huaibei-Huainan coalfields. Taking Luoyuan exploration area as an example, this paper analyzes the occurrence characteristics of coal seam and tectonic characteristics, exploration method and exploration model of coal resources in the complex geologic conditions areas. This paper emphasizes the importance of the regional tectonic framework and the coal controlled structural style of the coal resources exploration in the complex geologic conditions areas, and systematically summarizes the choice of the exploration technology, the arrangement of exploration project, the obtaining of the mining geological conditions. On this basis, the exploration model of coal resources is established in the complex geologic conditions areas, which makes full use of existing resources, strengthens the research of the regional tectonic framework, the coal controlled structural style and the mining geology conditions, takes the drilling and directional drilling as the principal exploration technology and auxiliary various exploration methods. It has achieved the integration of coal exploration and development, and has positive significance for the rise of the technical level of the coal resources exploration under the complex geologic conditions in the Huaibei-Huainan coalfields.

Key words: complex geologic conditions, coal resources, exploration method, exploration model, Luoyuan exploration area
