摘要
通过对赵官煤矿3702薄煤层综采工作面进行矿压观测工作,在分析观测数据的基础上,结合矿压理论和现场经验,得到了工作面正常回采过程中的运动参数和垮落规律,巷道围岩变形规律以及超前压力影响范围,并在此基础上确定了顶板类型,为相似地质条件下安全高效回收煤炭资源提供了依据。
Through the mineral pressure observation work of 3702 fully-mechanized face in thin coal seam in Zhaoguan Coal Mine,on the basis of analysis of mineral pressure observation data,combining with the mine pressure theory and field experience,the motion and caving law in the recovery process,deformation law of surrounding rock and the influence scope of advanced pressure are obtained.The roof type is determined,which provides guidance for the safe and efficient recovery of coal resources in similar geological conditions.
