摘要
根据谢桥矿现场实际观测数据,进行了分析研究,得到该条件下走向长壁综采工作面的顶板来压的显现规律及特点,以及支架与围岩的相互作用关系,为同类煤层走向长壁综采工作面顶板管理、确定工艺参数建立了依据。
Basede on the results of observation, the regularity of groud behaviour of the roof of the longwall strick Machanized mining face and the relation between support and surrouding rock is discovered to supply the scientific evidences for management of roof of the same seams and for determing parameter.
