摘要
利用系统刚度的概念,从刚度的角度来探究采高的增加对于支架刚度要求的变化情况,并且结合皖北矿区任楼煤矿Ⅱ7211工作面的实际地质情况,来反映采高的增加对支架刚度要求的变化。结果表明:采高的增加对于支架刚度的要求确实会有很大的提高,并且在不同的地质条件下,相同采高的工作面对于支架刚度的要求也是不同的。
By using the concept of system stiffness,the stiffness of theangle ofthe increase of mining heightto changing support stiffness requirements,and the combination of Renlou mine in Wanbei mining areaof 7211 working face ofthe actual geological conditions,to reflectthe increase of mining heightmakes the tiffness of supports requirements changes.The results show that the mining height increase will indeed have greatly improved the stiffness of support requirements,and in different geological conditions,even though mining working face inthe same height.
