福建省地处中国东南沿海，含煤地层主要为中二叠统童子岩组。煤类相对单一，98%为无烟煤；煤层厚度小，绝大部分为薄煤层；童子岩组煤系被多期次构造运动破坏，构造复杂，尤其是含煤地层内及上覆、下伏地层之间广泛发育多层次的缓倾角断裂，成为福建含煤地层的主要控煤构造。在长期的勘查实践中，福建煤田地质工作者基于对控煤构造的研究，首次提出福建煤炭勘查理论——滑脱构造理论，该理论在找煤工作中发挥了重要作用。随着勘查实践的不断深入，发现该理论在指导隐伏区找煤中存在一些问题，针对这些问题本文对滑脱构造理论进行了重新厘定，将原定义的滑脱构造分解为滑脱构造、滑覆构造、推覆构造三类。

The Fujian Province is situated on the coastal southeastern China. The main coal-bearing strata belong to middle Permian Tongziyan Formation; coal ranks are relatively homogeneous with 98% anthracite, small coal thickness, and mostly thin coal seams. The coal measures in Tongziyan Formation were disrupted by multiple staged tectonic movements thus presented into complex struc?tures. Especially between coal-bearing strata and overlying, underlying strata have developed multi-level gently dipping fractures ex?tensively, prove to be main coal controlling structures in coal-bearing strata in Fujian. During the long-term exploration practices, on the basis of coal controlling structural studies, Fujian coal geologists first proposed the Fujian coal prospecting theory—detachment structure theory and played a prominent part in coal prospecting works. In pace with steadily intensified prospecting practices, have found some issues in guiding of concealed area coal prospecting from the theory, in allusion to the issues, the paper redefined the de?tachment structure theory, disassembled the original detachment structure theory into decollement structure, gliding nappe structure and nappe structure three parts.
