摘要
以桃园煤矿7246工作面为研究对象,通过对工作面支架工作阻力的实测分析,揭示了大倾角薄煤层综采工作面的矿压显现规律,分析了液压支架运行状况及对72煤层顶底板的适应性,对今后生产实践具有指导意义。
Taking 7246 coal face in Taoyuan Coal Mine as an example,by measuring and analysis on the working face support resistance,the law of mine pressure behaviors is revealed, which is at a fully mechanized face in a thin coal seam with large inelined angle,and the operation condition of hydraulie supports and the adaptability for the roof and floor in 72 coal seam are analyzed,for future production practice signifieance.
