寺河矿大采高超长工作面初撑力与采场控制分析
首发时间:2010-01-15
摘要:为了能够更好的维护工作面顶板,对采场矿压进行控制,采用回归分析法分析支架初撑力与工作阻力的关系,以及现场观测的方法了解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。必须采取措施提高支架初撑力,保证支架初撑力达到规定值。

Setting Load and stope Control Analysis of Si he Mine long face with large mining height
Abstract:In order to safeguard face roof well and control stope ore pressure ,using regression analysis method, in this paper analyses the supports in the relationship between the resistance force and work, And on-site observation approach to the stope mining pressure effects under the initial setting load. Analysis shows that: Setting Load improve resistance will also increase accordingly, as the Setting Load increased, Support resistance can be played very fast and is conducive to roof management. So must take measures to improve the supports in force to ensure the supports in force up to the required value.
Keywords: Hydraulic support Setting Load of support Working resistance
