沿空留巷技术在煤矿的实践与应用
Practice and Application of Gob-Side Entry Retaining Technology in Coal Mines
摘要:
本论文通过对棋盘井煤矿11101工作面运输顺槽沿空留巷的支护条件、施工工艺的认真分析；并详细阐述了回采巷道顶板预裂切缝，恒阻锚索补强加固技术，挡矸及临时支护技术，为工作面掘进提供了新的思路和新的技术工艺，有力地促进了工作面安全高效地生产。
Abstract:
This paper carefully analyzes the support conditions and construction technology of the gob-side entry retaining along the 11101 working face of Qipanjing Coal Mine; elaborates on the roof pre-split and cutting seam of the mining roadway, and the reinforcement technology of constant resistance anchor cable, gangue blocking and temporary support technology; provides new ideas and new technical processes for working face excavation; and effectively promotes safe and efficient production of working face.
