摘要
以西曲矿近距离煤层采空区下29205综采工作面为研究对象,通过现场实测掌握了该工作面初次来压、周期来压步距,来压强度、超前支承压力影响范围和强度等矿压显现特征。通过对比非采空区下19101综采工作面矿压显现特点,认为近距离煤层采空区下开采矿压显现相对较弱,为指导类似工作面开采提供了依据。
Take 29205 working face with close- distance coal seam under goaf of Xiqu Colliery as the research object, the author presents the characteristics of the initial pressure, the periodic pressm＇e step distance, the pressure intensity, the influence range and the strength of the pre bearing pressure through the field measurement and compares with the characteristics of strata behavior at 19101 fully mechanized working face under the non-goaf, which shows the strata behavior in close distance coal seam under goaf is relatively weak and provides guidance for similar working face.
