邢台矿建筑物下充填开采沉陷规律的研究

为了保护井巷、建筑物、水体以及铁路等,使它们免受或少受开采的有害影响,减少地下资源的浪费,邢台矿首次采用建筑物下综合机械化充填采煤技术进行工业广场下开采,本文介绍了建筑下综合机械化充填采煤技术的主要思路,针对7606充填工作面建立岩移观测站,总结了开采沉陷规律及预计参数,并通过7608充填工作面对预计参数进行验证。结果显示:预计移动参数选取合理,预计方法正确,预计结果能较好的反映矸石粉煤灰充填开采的地表移动变形规律。

Research on subsidence rule of filling mining under buildings in Xingtai Coal Mine

In order to protect the roadway,building,body of water and railway from the harmful effects of exploita-tion,and reduce waste of underground resources,the fully -mechanical technology of filling mining under buildings is used for mining under industrial squares in Xingtai Coal Mine for the first time.This paper introduces the main i-deas of the fully -mechanical technology of filling mining under buildings.A rock movement observation station is established for the 7606 filling working face,the rules and the predicted parameters of mining subsidence are sum-marized,and then the predicted parameters are validated through 7608 filling working face.The results show：the se-lection of the predicted moving parameters is reasonable with correct method,and the prediction results can reflect the deformation characteristics of surface movement in filling mining of gangue fly ash.
