摘要
以谢桥煤矿1242(1)首采工作面为例,分析了综采工作面矿山压力显现特征、顶板活动规律、液压支架的性能和对该煤层顶底板的适应性及控制效果、工作面顺槽超前支承压力分布,对初次来压期间和周期来压期间支架载荷特征进行了较为系统的分析,为后期开采11-2煤层积累了经验。
Taking the first coal face 1242(1) in Xieqiao coal mine as an example, the paper analyzes the regularity of strata behavior for fully mechanized working face, moving regularity of roof, performance and adaptability of hydraulic support and abutment pressure distribution of roadway. Meanwhile, the characteristic of support load during first and periodic weight of the main roof was studied . All these supply valuable experiences for extracting 11-2coai seam.
