摘要
通过矿压观测对支架立柱工况进行了连续观测与记录,同时对顶板运动特点、支架及输送机等主要设备的损坏情况进行了专项观测,分析了工作面在调采时ZY3400/14/34型支架的适应性。通过实测统计确定了支架的合理工作阻力,并对支架在调采面中存在的主要问题进行了分析,得出了较为重要的结论。
For studying adaptability of the supports, the operating system of hydraulic supporter was continuously observed and recorded through conventional observation of rock pressure, meanwhile dedicated observation was taken for motion characteristics of roof and equipment damage of conveyor and supports. The ZY3400/14/34 supports appropriate working resistance was determined by measured statistic, analyzed subject matter existing in supports, concluded more important conclusion.
