摘要
通过对15206厚煤层综放工作面回采期间覆岩顶板破断失稳规律进行理论分析,以及对回采期间支架工作阻力的分布状态和工作特性进行分析。结果表明:工作面的周期来压步距约为14.5m,来压期间影响范围约为3.31m。
Through theoretical analysis of roof breakage and instability during mining in 3107 thick seam fully mechanized top coal caving face,the distribution and working characteristics of support resistance during mining are analyzed.The results show that the interval of periodic weighting is about 14.5m and the influence range is about 3.31m.
