摘要
为了获得回采期间厚煤层综放工作面侧向支承压力分布情况,基于回采工作面矿山压力理论,通过在回采工作面轨道顺槽外侧煤体中布置钻孔应力计,对回采期间及顶板垮落后巷帮受力进行监测,进而摸清工作面侧向支承压力的分布规律,为工作面区段煤柱留设提供依据。
In order to obtain the distribution measurement of lateral abutment pressure of thick seam fully mechanized caving face during mining,by layout of the drilling strain gauge in the outside of mining roadway for fully mechanized sublevel caving face,monitor the stress changing of roadway in the period of mining and after roof collapse,and then find out the distribution measurement of lateral abutment pressure,provide a basis for the section coal pillar's reserve of thick seam fully mechanized caving face
