综采工作面回采巷道位移观测分析

The Observation and Analysis of Stopway Displacement in the Fully Mechanized Working Face

为研究太兴矿63011工作面回采巷道深基点的位移变化,在回采巷道布置深基点位移观测站,采用四基点数显深基点位移计对采动过程中的深基点位移进行观测分析,共进行6组顶板位移观测和两组全断面深基点位移观测。通过对观测数据的分析,得出63011回采巷道受到采动影响很小,深基点位移都比较小。顶板受采动影响后的最大位移量都不超过0.6 cm,两帮受采动影响后的位移量都小于0.01 cm。巷道受采动影响后的位移量主要发生在0~3 m内。

To study the 63011 mining face of deep base displacement change,decorate in the roadway,the deep basis points displacement observation,using four basis points display deep point displacement meter on mining the deep basis points in the process of displacement analysis,a total of 6 groups of roof displacement observation and two sets of full face deep point displacement observation in Taixing Coal Mine.Through the analysis of the observation data,it is concluded that the 63011 mining roadway is very small and the displacement of deep base point is relatively small.The maximum displacement of the roof was not more than 0.6 cm after the influence of mining,and the displacement of both groups was less than 0.01 cm.The displacement of roadway affected by mining is mainly in 0~3 m.
