深井大倾角厚煤层无煤柱开采架后临时支护技术
|
摘要
以福城矿业有限公司1906S工作面切顶卸压自动成巷无煤柱开采工程为背景,对深井大倾角厚煤层切顶卸压架后临时支护进行研究,确定实行"36U型钢棚+联板"的挡矸支护方式,采用"一梁三柱"配走向联柱有效支护留巷顶板,确保了成巷效果,对于切顶卸压沿空留巷技术在深井大倾角厚煤层开采中的推广应用具有重要的借鉴意义。
Based on the background of the cut-top pressure relief and no-column self-aligning roadway of 1906 S working face of Fucheng Mining Co., Ltd., this paper studies the temporary support after roof-cutting and pressurerelief frame in deep seam with large dip angle and thick seam, determines the gangue-retaining support mode of "36 U steel shed + connecting plate", adopts "one beam and three pillars" with striking connecting pillars to effectively support the retaining roof of roadway, ensures the effect of roadway-forming, and retains pressure-relief along the goaf. The popularization and application of roadway technology in deep deep inclined thick seam mining has important reference significance.
