摘要

以西陈庄矿3201回采工作面为研究对象,分别对老顶初次来压和周期来压前后支架工作阻力进行对比,得到工作面来压时支架阻力变化规律,并通过现场观测得到工作面顶围岩变形量。采用FLAC3D数值模拟软件对工作面超前支承压力进行数值模拟,根据工作面不同推进距离围岩应力图,得到工作面超前支承压力的影响范围和峰值位置。
        Taking the 3201 mining face of the Xichenzhuang Coal Mine as the research object, this paper compared the working resistance of the support before and after the initial pressure and the periodic pressure of the upper top and obtained the variation law of the support resistance when the working face is pressed. And through the field observation, the deformation of the top surrounding rock of the working face was obtained. The FLAC3 D numerical simulation software was used to simulate the advanced support pressure of the working face. According to the diagram of surrounding rock stress of the different working face with different advance distance, and the influence range and peak position of the advanced support pressure of working face were obtained.
