火成岩侵蚀条件下不稳定煤层矿压显现规律探讨

Study on the behavior of igneous rock erosion under the conditions of unstable coal seam underground pressure

以杨营矿井3101工作面为背景,研究在该矿特有的地质条件下采场顶板岩层及煤层受采动影响的情况变化,从而掌握工作面的初次来压、周期来压等矿压显现规律及单体液压支柱对该地质条件的效能,也为今后的工作面开采支护方式、顶板的管理提供必要的矿压参数。

According to Yang Ying mine face 3101 face as background, research on the geological conditions of the mine this unique under the roof and coal affected by the change of mining, so as to master the first working face pressure, cycle to pressure behavior law of mine pressure and make the single hydraulic prop on the geology the performance, but also for the future of the working face mining support, top management to provide the necessary pres- sure parameters.
