| 摘 要： | 为了预测预报浅埋煤层综采工作面矿压事故灾害,采用KMJ30型采动应力监测系统对杨伙盘煤矿30108综采工作面矿压进行现场实测.通过综合分析初采期间、正常推进时期、末采期间支架实测数据,得出了工作面初次来压、周期来压平均步距,工作面倾向压力分布,工作面整体压力大小,以及特殊地段的矿压大小,掌握了工作面矿压显现规律,对杨伙盘煤矿及周边类似条件矿井矿压事故的预报与预防具有一定的指导意义.

| Abstract: | In order to forecast ground pressure disaster of fully-mechanized working face in shallow coal seam,mine pressure monitoring system(KMJ30) was put in use for monitoring ground pressure of 30108 fully-mechanized working surface.By analyzing the measured data of supports during the period of primary mining,normal mining and the end of mining,the average step distance of first weighting and periodic weighting,the distribution of face tendency pressure,the pressure of whole fully-mechanized face and the mining ... |
