摘　　要：针对开滦赵各庄矿3237深部大倾角综放工作面的矿压显现和围岩活动规律进行了全面的实测研究,通过多种观测手段和研究方法,获得了大量的观测数据,初步掌握了大采深大倾角厚煤层条件下综放开采工作面矿压显现的基本规律与顶板的运移特征,得出了大采深与大倾角回采巷道变形与支承压力的分布特征。According to the ground behaviors and the surrounding rock activity law of the No. 3237 fully mechanized caving mining face in deep high inclined seam of Zhaogezhuang Mine of Kailuan, a full site measurement research was conducted with multi measuring means and research methods. A great number of measured data were obtained from the site research. The basic law of the ground behavior and the roof migration features in the fully mechanized caving mining face under the deep mining depth and high inclined seam were preliminarily understood. The distribution features of the deformation and support pressure for the deep mining depth and high inclined mining gate were obtained.
