为研究神华布尔台煤矿在改变回采工艺后,42104工作面回采过程中矿压显现的发展变化,根据煤矿工作面实际地质条件,建立了煤层回采模型,运用数值模拟软件FLAC3D模拟综放回采过程中矿压显现过程并得到了来压规律。同时对工作面顶板压力进行现场监测,并对监测结果进行分析。
In order to study the development of mine pressure in 42104 working face after the change of mining process in Shenhua BOUTAI mine, a coal mining recovery model was established according to the actual geological conditions in coal face, and the numerical simulation software FLAC3D was used to simulate the process of fully mechanized top- Medium pressure shows the process and pressure to get the law. At the same time on-site monitoring of roof pressure and monitor the results of the analysis.
