为了能够更好地维护工作面顶板,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,采用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。
In order to be able to better maintain the roof of the working face and control the mine pressure, the regression analysis method was used to analyze the relationship between the initial support force and work resistance. The on-site observation method was used to understand the influence of initial support force on the rock pressure. The analysis shows that the initial resistance increases the work resistance, and the increase of the initial strength of the stent can make the work resistance of the stent quickly play and is conducive to the roof management. Measures must be taken to improve the initial support force to ensure that the initial support force reaches the specified value.
