Abstract
对国投煤炭郑州能源开发有限公司教学三矿15031工作面贯穿前后进行了矿压观测，通过编写VB程序对矿压观测数据进行处理，并使用统计分析软件对处理后的数据进行统计与分析。根据实测数据的统计值和绘制出的曲线图，确定了工作面贯穿前后的周期来压步距，研究了“三软”煤层工作面长度变化对矿压显现特征的影响。能够为矿山提供准确的数据资料，以指导生产中出现的工程问题。 Pressure observation was carried out at 15031 working face of Jiaoxue Mine in Dengfeng. The observation data were processed by programming with VB language, and then analyzed through statistical software. According to the statistical values and the graph, the step distances of periodical pressure around the connection of working face were defined, and the influence on the characteristic of pressure behavior with working face length was studied. The research provides accurate data for solving engineering problems in production.
