近距离煤层工作面支架工作阻力确定方法

Determination of Working Resistance of Support in Working Face of Short Distance Coal Seam

在平朔井工一矿近距离煤层协同开采的背景下,对4号煤14106工作面支架工作阻力进行确定。利用经验公式和数值模拟的手段,分析模拟不同支护强度条件下上方顶板下沉位移情况,确定顶板下沉位移与工作面支架支护强度之间存在的规律,最终选出合理支架。

Under the background of coal seam comining in Pingshuo mine, the working resistance of support in 14106 face of coal face is determined. By means of empirical formula and numerical simulation, the subsidence displacement of top roof under different support strength conditions is analyzed, and the law between roof subsidence displacement and support strength of working face is determined, and the reasonable support is selected finally.
