摘要
针对沿空巷道易受邻近工作面生产作业采动压力的影响导致巷道较难支护的问题,提出了沿空巷道的基本支护原则以及动压区临时强化支护的原则,强调了在实际支护作业中强化动压区支护的重要性,并由此得出了应依据各巷道的具体压力特征类别来科学合理地设计巷道支护的结论,供参考。
In view of the problem that the roadway along the empty roadway is often vulnerable to the influence of mining pressure of the adjacent working face,the roadway is difficult to support,puts forward the basic The basic principles of support and the principles of temporary strengthening of dynamic pressure zone support are proposed,and the importance of strengthening dynamic pressure zone support is emphasized in the actual support operation,and the conclusion of scientific and reasonable design of roadway support based on the specific pressure characteristic category of each roadway is drawn for reference of support along the hollow roadway.
