摘要
针对工作面矿压观测问题,通过分析工作面的岩层分布,设计了具体的支护方案以及矿压观测方案,研究了矿压规律.经现场应用,监测结果表明,在回采工作期间,基本顶的初次来压步距为29.1 m,周期来压步距平均为19.8 m,围岩变形量较小,支架的整体初撑力为23.5 MPa,说明工作面的支护效果较好.
Abstract
In view of the problem of mine pressure observation at the working face,by analyzing the rock strata distribution at the working face,a specific support scheme and mine pressure observation scheme are designed,and the rule of mine pressure is studied.Through field application,the monitoring results show that:During the mining work,the initial pressing step of the basic roof is 29.1 m,the average periodic pressing step is 19.8 m,the deformation of surrounding rock is small,the overall initial supporting force of the support is 23.5 MPa,indicating that the supporting effect of the working face is good.
