单体支柱在急倾斜走向长壁仰伪斜采煤法中的应用

The Application of Single Prop at Steep Pitch Longwall Mining on the Strike Operational Measures of False Coal Recovery

在急倾斜煤层中使用单体支柱,并研制出可靠的防丢柱窜柱联锁绳进行走向长壁仰伪斜式回采,工作面支护可靠,顶板易于管理,安全性能高,经济效益显著,为取消木支护、推广应用钢铁化支护开辟了一条新路子。

At steep pitch coal layer,the single prop is used.The reliable anti-lost column for channeling interlocking rope is developed to conduct longwall mining on the strike operational measures of false oblique style recovery.Working face support is reliable and the roof easy to manage.The safety is high and economic benefits significant which opened up a new road for the eliminating of timber support and promotion the application of steel support.
