特厚煤层综放液压支架主要支护参数的研究和探讨

Research and Discussion on Main Support Parameters of Thick Seam Powered Hydraulic Support

根据庞庞塔煤矿10号煤层地质条件、工作面开采及布置方式等情况,介绍了特厚煤层综放液压支架高度、工作阻力以及支架初撑力等主要支护参数的确定原则与方法。试验结果表明:支架的主要支护参数设计合理,安全性、可靠性高;提高了特厚煤层回收率,为工作人员和综采设备提供一个安全可靠的作业空间。

Coal mine on the lOth according to Pangpangta geological conditions, such as working face and the layout,the thick coal seam height of hydraulic support,resistance and support the work of setting load of the main support parameters such as the determination of the principles and methods were introduced. The results showed： support the rational design of the main support parameters, safety and high reliability; improve the recovery of thick coal seam for mining equipment and staff to provide a safe and reliable operation of space.
