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。
為瞭研究天池礦103綜放工作麵的頂闆運動規律,通過對工作麵液壓支架的阻力觀測,分析總結瞭103工作麵礦山壓力顯現的特徵,併得齣103工作麵來壓彊度不高,頂闆管理難度中等,以及工作麵支架的整體工作阻力偏低,不足額定的60%。可為工作麵的支護以及液壓支架的選型提供依據。

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.
