摘要
Abstract
In order to improve the resource utilization efficiency and carry on comprehensive development,the resource potential of coal in Zichang–Yanchuan mining area is necessary to be evaluated properly. Based on theories of sedimen-tary,coal geology and tectonic geology and current coal development situation survey results,the distribution pattern of coal-bearing formation of Late Triassic coal forming environment was studied using coal geologic exploration methods and well logging. It is concluded that the coal formed in T3y5 was deposited in braided river delta,lakeshore and shallow lake. The conditions of paleo-structure and paleo-climate controlled the formation of coal.关键词
