Establishment of 3D solid model for Meilinggou coalfield in Chengde area, Heibei, China.

Using the Kan-tan3D software developed by Micromine Co., Ltd, the authors establish 3D models for strata, structures and known coal seams in Meilinggou coalfield in Chengde area based on collected data from drill holes and geological sections along exploration lines. The models can rotate at any angles to facilitate observation and output section along any directional according to the purposes. These results provide some scientific reference basis for exploration, exploitation and economic evaluation of the local coal resources in future.
