摘　　要：为掌握石拉乌素煤矿首采工作面顶板活动规律及矿压显现特征和两顺槽超前支承压力影响范围及强度,通过实施2-2上201工作面及两顺槽矿压观测专项方案,自工作面推进开始进行了连续矿压观测,取得了大量的观测数据,对观测数据进行分析后初步获得首采工作面顶板运动规律,为工作面顶板管理和顺槽超前支护提供技术参考依据,同时也为矿井开采相邻工作面矿压观测和矿压规律研究积累经验。In order to grasp the roof movement law and the appearance pressure characteristics of the first mining working face in Shilawusu Coal Mine and the influence range and intensity of the advance bearing pressure of the two-slot trough,through the implementation of the special observation of the 20-second work face and the two-slot trough pressure The plan,continuous mining pressure observations have been carried out since the advancement of the working face,and a large amount of observation data has been obtained.After analyzing the observation data,the roof movement law of the first mining face is initially obtained,providing a technical reference for the roof management of the working face and advanced support along the groove Based on this,it also accumulates experience for the observation of underground pressure and the study of the law of underground pressure at the adjacent working face of the mine.
