摘 要: 为能够更好地维护工作面顶板、控制采场矿压,采用回归分析法分析支架初撑力与工作阻力的关系,并利用现场观测的方法分析初撑力对采场矿压的影响。分析表明:初撑力提高,工作阻力也相应增大;支架初撑力的提高,可以使支架工作阻力得到很快发挥,且有利于顶板管理。因此有必要采取措施提高支架初撑力,以保证支架初撑力达到规定值。
关 键 词: 煤炭能;液压支架;初撑力;工作阻力

Abstract: In order to protect face roof well and control stope ore pressure, this paper analyzes the relationship between the setting load force and work resistance using regression analysis method, and analyzes the effects of the setting load on the stope mining pressure using on�site observation approach. The analysis results show that: the work resistance increased accordingly as the setting load increased, and the support work resistance as the increase of the support setting load, the support work resistance performed function very fast, and it was conducive to roof management. So measures must be taken to improve the support setting load to ensure the supports in force up to the required value.
Key words: coal energy; hydraulic support; setting load; working resistance
