摘要
结合现场实测数据,应用MATLAB软件,分析研究了大倾角双斜工作面俯采段矿压显现规律及其与工作面俯角的相关性等问题。结果表明,大倾角俯采工作面矿压显现规律较为特殊,表现出周期来压步距相对较长,支护阻力沿工作面倾向呈现两种不同的分布特征,随着工作面俯角增大支护阻力显著降低等特点。
This paper applies MATLAB software to the analysis of strata-pressure behavior.It studies the strata-pressure behavior of downward mining and its relevance with the depression angle.The findings are that the strata-pressure behavior of downward mining has the following particularities: the periodic weighting span is relatively long,the support resistance takes on different distribution characteristics along the direction of face dip and the support resistance reduces remarkably along with the increase of the depression angle and so on.
