分析了沿空留巷巷道顶板岩层运动的过程及岩块之间的几何关系 ,得到了高水速凝充填体所需变形量的计算模型 .理论及现场实测结果都表明 ,目前所用高水速凝材料的可缩性不能很好地适应巷道顶板运动特性 ,必须加以改进
The process of rock strata movement and the geometrical relationship between rock blocks are analyzed and the calculation model of deformation required for high velocity condensate filled packings is obtained.The theoretical and field measurements show that the high water velocity The compressibility of the condensate material can not well adapt to the movement characteristics of roadway roof and must be improved
