| 摘 要： | 煤炭资源作为我国传统能源，在我国的经济建设中一直发挥着重要作用。随着煤炭资源开采技术的日趋成熟，及科学技术水平的不断提高，煤层的开采深度不断的向深部发展。煤系地层中的构造，尤其是滑动构造的发育对煤层的赋存及煤田地质构造有较大的影响。济源郭沟煤矿区HF1滑动构造是在本次勘查期间首次发现的。该滑动构造的存在，破坏了该区原有的沉积格局，使部分煤岩地层缺失或重复，导致煤层变浅或变深。另外受滑动构造的影响，该矿区二1煤层厚度变化较大，煤体结构破碎松软；滑体前后缘瓦斯成分和含量变化大，应该注意煤矿开采时滑体后缘瓦斯的危害。在济源郭沟煤矿区的施工过程中，通过建立煤岩标志层，综合研究对比发现了勘查区内HF1滑动构造的存在，分析了该滑动构造的形成原因及滑动面特征，以及滑动体的运动方向和滑移距离、形成原因。研究成果对本勘查区地质勘查工作的开展和取得后期成果起到了重要作用，也对后期煤田开采安全生产具有指导作用。

| Abstract: | As a traditional energy source in China，coal resources have always played an important role in China′s economic construction.With the maturity of coal resource mining technology and the continuous improvement of science and technology，the depth of coal seam exploitation continued to develop deeper.The structure in the coal-bearing strata，especially the development of the sliding structure，had a greater impact on the occurrence of coal seams and the geological structure of the coalfield.The HF1 sliding structure of Jiyuan Guogou Coal Mine was first discovered during this exploration.The existence of the sliding structure destroyed the original sedimentary pattern of the area，causing some coal rock formations to be missing or repeated，resulting in shallow or deep coal seams.In addition，affected by the sliding structure，the thickness of the Ⅱ1 coal seam in the mining area was relatively large，and the structure of the coal body was broken.The gas composition and content of the front and rear edges of the sliding body vary greatly.It should be noted that the gas at the trailing edge of the sliding body during coal mining should be harmed.In the construction process of the Jiyuan Guogou Coal Mine area，the existence of the HF1 sliding structure in the exploration area was discovered through the establishment of the coal rock marker layer.The formation reasons and sliding surface characteristics of the sliding structure and the sliding body were analyzed.The direction of motion and the distance of the slip，the cause of the formation.The research results have played an important role in the development of the geological exploration work in this exploration area and the achievement of the later results，and also have a guiding role in the safe production of coal mining in the later stage. |
