综采放顶煤工作面顺槽支护优化设计

Optimal design of mining roadway support in fully mechanized caving face

矿井综采放顶煤工作面顺槽受到综放工作面回采动压和周期来压的影响,巷道顶板围岩变形严重,影响生产安全。根据工作面顺槽围岩地质情况对原有支护设计进行了参数优化设计,并进行了现场观测。观测表明,经过支护设计优化的综采放顶煤工作面顺槽围岩变形得到有效控制,满足矿井巷道稳定要求。

The mining roadway of fully mechanized caving face is affected by the dynamic pressure and periodic pressure,and the roof deformation of mining roadway is serious,which affects the safety of production.According to the geological conditions of the surrounding rock of the working face,the parameters of the original support design were optimized and the field observation was carried out.The observation shows that the deformation of the mining roadway for fully mechanized caving face was effectively controlled by the optimized supporting,which meets the requirements of the mine roadway stability.
