摘要: 依据朱仙庄871综放工作面地质条件和旋转回采技术参数,利用数值模拟和现场钻孔电视的方法,对厚煤层综放工作面旋转回采技术进行了深入地研究,揭示了旋转段围岩力学特性。拐角处围岩应力集中较大,旋转拐角处煤体以及上覆一定范围内的顶板裂隙高度发育。

关键词: 综放工作面, 旋转回采, 裂隙发育, 应力集中

Abstract: Study on technology of rotation mining on fully mechanized caving face with high seam by using numercial simulation and axial view panoramic probe based on the geological condition and technical parameter of rotation mining with 871 fully mechanized caving face。There is some result that higher stress and fracture devep -ment on coal around the corner.

Key words: fully mechanized caving face, rotation mining, fracture development, stress concentration
