寺河矿大采高300m工作面采场控制分析

Analysis on the Stope Control of 300m Working Face with Large Mining Height in Sihe Coal Mine

为了能够更好地维护工作面顶板,对采场矿压进行控制,通过现场观测的方法了解了初撑力对采场矿压的影响,并采用回归分析法分析了支架初撑力与工作阻力的关系。结果表明:初撑力与工作阻力呈正相关,即提高支架初撑力可以使支架工作阻力得到很快发挥,以利于顶板管理。

In order to maintain better the roof of working face,the stope pressure was controlled,and through the field observation,the influences of setting pressure on stope pressure was mastered,and the relationship between supports’ setting pressure and working resistance was analyzed with regression analysis.The results show that there was a positive correlation between the setting pressure and working resistance,that is to say,increasing the setting pressure can make the supports’working resistance display very soon,which is beneficial to the management of the roof.
