大倾角综放工作面支架稳定性技术研究

Study on techniques of bracket stability in fully mechanized top coal caving mining face

为了解决葛泉矿1622综放工作面大倾角支架失稳问题,对现场实际进行了深入的探讨研究,并对产生支架失稳的情况进行了力学分析,提出了提高支架稳定性的几种技术措施。其措施在葛泉矿1622综放工作面开采中效果显著,在一定程度上解决了大倾角综放工作面支架失稳问题,保证了大倾角综放工作面的稳产高产。

Based on instability of large inclination support of 1622 fully mechanized caving mining face in Gequan Mine,mechanical analysis was made for instability of support in field practice and several technical measures about how to improve stent stability were put forward, which had outstanding effect on 1622 fully mechanized caving mining face. It not only solved problems of unstable suppport but guaranteed stable and high yield in fully mechanized top coal caving mining face.
