摘要
通过数值分析,研究得到回采面顶板沿走向、倾向以及不同工作阻力垮落、冒落特征及工作面矿压显现规律,确定了工作面的合理支护参数,为工作面顶板控制及矿井的安全高效回采提供了依据。
Through the numberical analysis, the characteristics and rules of working face strata behaviors, caving and collapse along alignming and inclining to coal roof and under various working resistance are acquired. Make sure the reasonable supporting parameters of working face, which provides basis for coal roof controlling and safely and efficiently coal mine working.
