摘要
在对中厚煤层沿空留巷技术特点、围岩结构特征等进行分析基础上,本文结合屯兰矿18401工作面实际情况,利用FLAC3D软件对沿空留巷充填体的宽度参数进行了对比研究,然后对该工作面所采用的回采工艺流程和关键工序等进行了分析。本文研究内容可为中厚煤层沿空留巷工艺方案的制定和实施提供有益借鉴。
on the basis of the analysis of the technical characteristics and the structure characteristics of the surrounding rock in the middle and thick coal seam,this paper makes a comparative study on the width parameters of the filling body in the goaf with the 18401 working face in tunlan mine by the FLAC3D software,and then the mining process and key working procedure adopted in the working face are analyzed.The research contents in this paper can provide a useful reference for the formulation and implementation of the process plan for gob side entry retaining in medium thick coal seam.
