摘要
为了研究天池矿103综放工作面的顶板运动规律,通过对工作面液压支架的阻力观测,分析总结了103工作面矿山压力显现的特征,并得出103工作面来压强度不高,顶板管理难度中等,以及工作面支架的整体工作阻力偏低,不足额定的60%。可为工作面的支护以及液压支架的选型提供依据。
In order to study the roof movement law of 103 fully mechanized caving face in Tianchi coal mine, we observed the resistance of hydraulic support, and analyzed the characteristics of mine pressure appear. So we obtained the compressive strength is not high and the roof is easy to manage, as well as resistance of hydraulic support is low, less than 60% of the rated, which can provided the guidance to the support of work face and selection of hydraulic support.
