摘要
塔山特厚煤层综采放顶煤过程中,工作面矿压显现剧烈,通过现场实测、观测数据整理找出其显现规律,结合地质条件、设备使用情况等分析其原因,并提出改善措施,并在实践中取得了较好效果。
Behavior of underground pressure during full-mechanized caving mining extremely thick coal seam in Tashan Colliery was very strong. Rules of underground pressure behavior were obtained with observation data. By analyzing causes of strong pressure with geological conditions and equipment utilization status, improvement measures were put forward. Good effect was obtained in practice.
