薄煤层综采面切眼布置的创新技术探讨

Probe into Innovative Technology of Open-off Cut Layout at Fully-mechanized Working Face with Thin Seam

在薄煤层综采工作面切眼巷设计时直接将支架降到煤层高度,将支架顶梁前部分完全伸入煤层支撑接顶,将底座放在切眼巷后部起支撑作用,就有了在切眼巷布置前、后腰巷的设计。采煤机割煤过后通过及时拉架便可完全控制顶板冒落,解决了回采初期顶板管理困难的问题,经济效益显著。

The layout of front and back lane is applied to open-off cut design by reducing the support to the height of the coal seam, stretching the front section of roof beam into coal seam to leg up and laying the base at the back of open-off cut, which can solve the roof management difficulties in early stage of recovery by dragging the erection to control roof falling.
