| 摘 要： | 为探明膏体充填工作面沿空留巷矿压显现规律,对高河能源E1302膏体充填工作面沿空留巷进行了测站布置与数据处理分析,结合充填体应力数值模拟分析,证明了膏体充填工作面矿山压力显现不明显,巷道变形经历了由缓到急再到缓的过程,巷道顶底板移进量和移进速度整体大于两帮移进量和移进速度,但是巷道整体变形量较小.

| Abstract: | In order to find out the mine pressure behavior law of retaining roadway along goaf in paste filling working face,the station layout and data processing analysis of gob-side roadway retaining in the E1302 paste filling working face of Gaohe Energy were carried out.Combined with the numerical simulation analysis of filling body stress,it is proved that the mine pressure in paste filling working face is not obvious,and the roadway deformation goes through the process from slow to urgent and then to slow.The moving amount and speed of the roof and floor of the roadway are larger than that of the two sides,but the overall deformation of the roadway is small. |
