沙曲矿北翼大采高综采面的支架合理工作阻力确定

Determination of The Reasonable Support Resistance of the Thick Seam in the North-wing of Shaqu Coal Mine

根据沙曲矿3～4号合并层的顶板岩层结构与矿压观测实际结果,应用两种综采工作面支架合理工作阻力的确定方法:实测数据;矿山压力基础理论的'砌体梁结构力学'模型.确定了合理的支架工作阻力参数.

To set the reasonable parameter of support working resistance, we apply the reasonable support resistance in fully mechanized face,such as by actual observation,by a regression formula and by the mechanical model of 'bond beam structure' in basic theory of roof pressure, in accordance with 3-4# amalgamated layer in Shaqu coal mine and the observing result of roof pressure.
