大倾角松散厚煤层不规则综放工作面开采技术研究与实践∗

摘要

介绍了太平煤矿在大倾角松散厚煤层条件下的不规则工作面综放开采技术研究成果。工作面采用多工艺联合交叉施工方式，并在向斜轴附近采用旋转开采的工艺，同时采取了煤体注水、支架挂网预防漏顶等技术措施，取得了极其复杂地质条件下松散厚煤层综放开采的成功。%In the paper,the research results of mining technology for irregular fully mecha-nized caving face in steep loose thick coal seam in Taiping Coal Mine are introduced�� The con-struction way of j oint cross process is adopted in the face,and the revolving mining process is used near the synclinal axis,and meanwhile,the measures are adopted including coal body infu-sion and support with mesh to prevent the roof leakage,which have helped to achieve the success of fully mechanized caving in loose thick coal seam with extremely complex geological conditions.
