深部非充分采动岩移参数反演拟合研究
|
摘要
平顶山矿区香山矿目前采用的岩移参数是15年前矿井在回采浅部煤层(采深200~300m)时通过实测获得的。随着回采深度的增加,岩移参数也会发生变化。本文通过香山矿己16-17-24061工作面实测的下沉值,运用反演拟合的方法,拟合出深部煤层非充分采动(采深750m左右)的岩移参数,并与浅部煤层回采岩移参数相比较,得出两者之间的差别,为相似地质条件下深部非充分采动岩移参数的选取提供借鉴。
The rock shift parameters used in Xiangshan mine in Pingdingshan mining area are obtained 15 years ago when the mine was measured in the shallow coal seam(200 m to 300 m). With the increase of mining depth, the pa-rameters of rock movement will also change. Through the inversion fitting method, the rock shift parameters of thedeep coal seam were not fully produced(about 750 m in the mining depth)by the inversion fitting method, and thedifference between the two in the shallow coal seams was compared with that of the shallow coal seam, which was thedeep non sufficient mining rock under the similar geological condition. The selection of moving parameters could be used for reference.
