摘要: 针对综采工作面生产的精细化管理需求，提出了一种综采工作面区域网格化分区方法。以综采工作面空间区域及作业循环图表为依据，在静态层面将综采工作面区域划分为回风端头区域、头三角煤区域、中部采煤区域、尾三角煤区域和进风端头区域；结合生产过程中割煤、移架和推溜3个工序，进一步对中部采煤区域进行动态分区，划分为割煤区域、移架区域、推溜区域和过渡区域。以综采工作面矿压特征分析为例，说明了网格化分区后的矿压特征分析结果相对工作面整体区域矿压特征分析结果具有更强的针对性。Abstract: In order to meet fine management requirements for fully-mechanized coal mining face production, a grid partition method of fully-mechanized coal mining face area was put forward. According to space area of fully-mechanized coal mining face and operation cycle chart, fully-mechanized coal mining face area was divided into return air terminal area, head triangle coal area, central coal mining area, tail triangle coal area and inlet air terminal area from static level. Considering three processes of coal cutting, support moving and scraper conveyor pushing in production process, the central coal mining area was further dynamically divided into coal cutting area, support moving area, scraper conveyor pushing area and transition area. Taking mine pressure characteristics analysis of fully-mechanized coal mining face as an example, it shows that analysis results of mine pressure characteristics after grid partition are more specific than those of whole working face.
