| 摘 要： | 以王楼煤矿11301综采工作面为研究对象,首先对顶板岩梁的运动步距进行理论计算,包括直接顶的初次垮落步距,老顶的初次来压步距以及岩梁的周期来压步距,然后通过对综采支架工作阻力和巷道围岩变形实测,确定了工作面顶板岩梁的运动步距,从而为综采工作面顶板管理提供了技术支持。

| Abstract: | This paper based on Wanglou coal mine 11301 full mechanized working face.It made a theoretical computation the movement step of rock grider firstly,including the first immediate roof caving step,the initial weighting step of main roof and the periodic weighting step of rock grider.Then it did an actual measure and analysis about the fully mechanized support working resistance and the roadway wall rock distortion,resulted the roof movement step of the working face,make a nice technique condition for controlling roof of the full mechanized working face. |
