摘要
为了探明煤层薄化带与煤层层间滑动构造的关系,得出矿区薄煤带展布特征及分布规律,给矿井安全生产提供超前地质信息。通过对潘集一矿主采煤层薄化带及其增厚带的展布方向和幅度变化研究,了解并揭示其展布规律,分析其与煤层层间滑动构造的关系。研究结果表明:揭露潘集矿区19个煤层薄化带,薄煤带的产生主要是由于煤层与顶底板之间的层间滑动造成的。层间滑动的方向与薄煤带展布方向具有相互垂直的特点,中部层滑构造相比于西部发育,主要是由于中部构造较复杂,显示了层滑构造与矿区的构造具有相对应、相伴生的关系。
In order to explore the relationship between the thin seam zone of the seam and the seam sliding structure of the seam, to have the distribution features and the distribution law of the thin seam zone in the mining area and to provide the in advanced geological information to the mine safety production, with the research on the distribution direction and the cope variation of the thin seam zone and the thickness increased zone in the main mining seam of the Panji No. 1 Mine, the distribution law was understood and released and the relationship between the seam and the seam sliding structures was analyzed. The research results showed that there were 19 thin seam zones in the Panji Mining Area and the thin seam zones occurred mainly by the strata sliding between the seam and the roof as well as floor. There was a mutual vertical features between the strata sliding direction and the thin seam zone distribution direction. The strata sliding structure in the middle seam was more developed than the west part seam mainly due to the structure more complicated in the middle seam, All those showed that there was the related correspondence and the related associated relationship between the strata sliding structure and the mining area structure.
