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。
By observing the pressure of fully mechanized coal mining face of 3702 thin coal seam in Zhaoguan Coal Mine, based on the analysis of observation data and combining with the theory of mine pressure and field experience, the movement parameters and caving law of normal mining face are obtained, The deformation law of roadway surrounding rock and the influence range of advance pressure, and on this basis, the type of roof is determined, which provides the basis for safe and efficient recovery of coal resources under similar geological conditions.
